The EasyControl is available in black and white.
Forever. The settings are stored on the EasyControl itself. When the thermostat is reconnected, it will connect to the Bosch internet server and retrieve the correct time and date.
In the event of a power cut:
- The EasyControl does not have power and the heating appliance is switched off.
- The EasyControl remembers last set settings.
- As soon as the power returns, the thermostat reboots, the current time is retrieved from the internet server and the appliance restarts according to the clock program.
No, automatic updates cannot be switched off. The thermostat automatically checks for updates on the server, which install automatically. The thermostat stays up-to-date so you can benefit from any product improvements.
No, the EasyControl is sold including the free EasyControl app. The app contains all the features you need and is available can be downloaded from the Apple App Store and Google Play.
Yes, you can. Simply update the location in the app. You can also return the EasyControl to factory settings by pressing the thermostat’s reset button with a paper clip, but you will lose your current clock program. For more information, see the user manual.
For reference, it is highly recommended that you use a calibrated thermometer. Your installer can assist you with this. If necessary, you can calibrate the EasyControl in the app.
Currently the system has been designed with the assumption that Smart Radiator Thermostats are installed on every radiator, if there is no Smart Radiator Thermostat installed in the same zone as the EasyControl then heating will not be triggered. If you are experiencing this issue, then you must install or move a Smart Radiator Thermostat into the same zone as the EasyControl. N.B. the zone assigned to the Smart Radiator Thermostats can be assigned and changed within the EasyControl App, in the menu SettingsRoomsConnected Devices
Application & Operations
Please refer to your appliance manual or contact your installer to confirm whether it supports thermal disinfection. If this feature is available, the EasyControl will show this in the app (in the hot water settings menu).
Yes, the EasyControl is a modulating thermostat. Modulating appliances with modulating thermostats regulate the temperature more efficiently than other heating systems. Please note: if the EasyControl is connected to an on/off appliance via the EasyControl Adapter, the heating system will not modulate.
In conjunction with the EasyControl Adapter you can also control on-off appliances. Thereby district heating (on-off) appliances are supported too.
No, EasyControl connects via Wi-Fi only meaning a wireless network is necessary.
- The EasyControl is compatible with EMS 1.0 and EMS 2.0 appliances from the following brands: Worcester, Bosch, Nefit, elm Leblanc, Vulcano and Buderus.
- With an EasyControl Adapter, the EasyControl is also compatible with appliances that use the OpenTherm protocol and appliances with an On/Off interface (between 18-230Vac).
The EasyControl supports the following type of appliances:
- Modulating Worcester Bosch boilers via the EMS connection
Also, when installed with the EasyControl Adapter:
please note: extra power socket needed):
- OpenTherm appliances
- On-off appliances
- District heating (on-off) appliances
The functions supported by EasyControl can vary depending on the appliance connected. For more information on the features supported please check our FAQs.
Not yet. The EasyControl will provide an open interface to smart home systems. This interface shall be available later.
First of check that you have installed your EasyControl correctly as per the installation guide (PDF 3.4 MB) . We recommend that the EasyControl is installed by a competent person, find an accredited Worcester Bosch installer here .
If you still require assistance or dedicated controls team can be contacted via 0330 123 3641
Only one EasyControl can be connected to one individual heating appliance. To control the temperature in the different rooms of you home, we recommend using the Smart Radiator Thermostats.
If the EasyControl is connected to a Worcester Bosch boiler, a connection resistor is not required. If you want to connect EasyControl to an OpenTherm boiler, consult the installation instructions of the desired OpenTherm boiler.
For now, the installation of the EasyControl requires a wired connection to the boiler.
No, this is not currently possible. You would have to log out of one EasyControl, and into another.
By default, the EasyControl thermostat is suitable for most new Worcester Bosch Combi boilers, in this instance the EasyControl Adapter can be used as a signal booster. A full compatibility list can be found here (PDF 0.1 MB)
When wanting to use an EasyControl with an older Worcester Bosch Combi or with another brand of heating appliance via the OpenTherm or 230v on/off connections a EasyControl adapter should be used.
If installing the EasyControl as a single channel time and temperature control in S and Y plan systems, the EasyControl adapter should be used.
Depending on which connection type is chosen there are different levels of functionality that is available. The highest level of functionality comes when connected to a Worcester Bosch appliance via the EMS terminals. The least comes when connected via a 230v connection.
The thermostat’s touchscreen is only as big as the circle. If you touch the screen outside of the circle and then swipe into it, the thermostat will not detect the movement.
Motion Sensor & Display
No, this is not possible. The display turns on automatically if something or someone is within a 1 meter radius of the thermostat, and it switches off after 5 minutes if no movement has been detected.
The 'proximity detection' can be switched off in the ‘Settings – Thermostat’ menu. If there is a mirrored surface in front of the EasyControl, the 'proximity detection' won’t work properly. If that is the case, switch off the 'proximity detection' function.
Please verify the settings in your app. It might be that proximity detection is turned off. This could also happen when the EasyControl is installed in front of mirrored surfaces. The settings of the proximity sensor can be changed in the EasyControl app.
The lowest temperature you can set is 5 °C. Your Worcester Bosch appliance is also equipped with frost protection.
The outdoor temperature is retrieved from the internet. Your location is defined when you set up the EasyControl app during the on-boarding wizard. These coordinates are used to define your local outdoor temperature. The outdoor temperature is used for Weather-Dependent Control. It can also be shown in the Heating Settings menu.
Depending on the appliance type, this information might not be available for the EasyControl to display.
The EasyControl app supports several languages. Change the language settings on your smartphone in order to use the app in a different language.
Yes, the EasyControl allows you to measure the humidity in the room. The optimal humidity depends on personal needs, clothing, physical activity and the time of year. Usually the optimum value is between 45% and 55% humidity.
Yes and it is very easy to set it up as there is no need to install an external temperature sensor. The EasyControl will retrieve the outdoor temperature from an internet service and the weather-dependent settings can be easily adjusted in the EasyControl App in the Heating Settings menu.
Yes, it does work with an EMS outdoor sensor. If the EMS outdoor sensor is present and connected, its values are used. If no outdoor sensor is connected, the EasyControl uses the local outdoor temperature taken from the internet.
No. A Weather-Dependent Control program provides a greater level of comfort to the user. In this program, the outdoor temperature determines the supply temperature. If you choose, all the rooms in the house will be heated. A room control program heats the reference room based on the temperature of that room. That is usually more economical.
Using Weather-Dependent Control within a system with Smart Radiator Thermostats heats rooms more efficiently because you can define an individual clock program for each room so they will be heated only when the rooms are in use.
The Weather Dependent Control settings can be changed in the Heating Setting menu in the EasyControl app.
The fireplace function ensures that, when using the fireplace, rooms other than the reference room can be heated. When you use the fireplace, turn on the fireplace function in the app. The room control program then temporarily switches to weather-dependent control, providing the outside temperature from the internet if no outdoor sensor is connected. The fireplace function uses a default supply temperature. If it turns out that not all rooms are at the desired temperature, consult your installer.
You can choose between 4 options: 0, 1, 2, 3
- None (0)
- Low (1)
- Medium (2)
- High (3)
This is best shown with an example; the heating curve is set to:
- Heating type: Radiators
- Start point curve: 25 °C
- End point curve: 80 °C
- Room influence: High (3 °C)
The following switching point is programmed/active in the clock program; Get up at 7:00 a.m. = 20 °C.
Let's say the EasyControl is measuring 16 °C that morning, the heating curve is then shifted upwards in parallel. This shift is calculated as follows:
- (Setpoint clock program = measured room temperature) x room influence (20 °C – 16 °C) x 3 °C = +12 °C (supply water temperature).
As the measured room temperature rises, the parallel shift will decrease. Once the measured room temperature has reached 20 °C, the heating curve will no longer be shifted in parallel because: (20 °C – 20 °C) x 3 °C = 0.
It is possible to calibrate the EasyControl temperature measurement in the EasyControl app settings. The value can then be adjusted up or down. You can increase the temperature shown by adjusting the temperature in the app by 2 °C in steps of 0.5 °C and decrease as well.
Your smart device is connected to your router via Wi-Fi. In case of a broken server connection, EasyControl uses the time on your smart device. To do so, open the EasyControl app. The clock program will continue to function properly.
The EasyControl has a default clock program. After a factory reset, the default clock program will be active again. You can change it according to your needs in the EasyControl App.
Each day there is a maximum of 6 switching points for central heating.
Clock Program/Domestic Hot Water (DHW)
No, the DHW temperature can only be set on your Worcester Bosch boiler. Consult the operating instructions of your boiler to see how this works.
Yes, appliances with instantaneous water heating will create hot water in the middle of the night. The ECO mode switches off water heating at night if "Sleep" and "Absence" are set in the time programme.That way, the boiler saves energy. After turning on the tap, it will take longer to get DHW because the warm-up function is switched off in eco mode. That means there is DHW in the middle of the night, but with a slightly longer waiting time.
The hot water auto mode heats DHW according the DHW clock program. Each day there is a maximum of 4 switch points for DHW.
Yes, you can. The ‘optimum start’ is activated by default. The desired temperature is then reached by the set time in the clock program. You can turn this function off if desired.
Menu – Scheduling – Heating – Optimum start in the EasyControl app.
- Does not work: ‘Optimum start’ is applied by default. You can (dis)able this function: Menu – Scheduling – Heating – Optimum start in the EasyControl app.
- Does not work properly: speak to the installer to check that your installation is configured correctly.
- When the EasyControl has just been installed, the thermostat still needs to learn the optimum start time.
During initial commissioning, the first user defines the EasyControl password. If you forgot the password and cannot access the EasyControl through its app then the EasyControl must be reset (please note: all settings will be lost). Please read the manual on how to reset the EasyControl.
The credentials are essential for gaining access to the EasyControl with a smart device. A sticker on the front cover of the quick reference guide contains the serial number and access code (alpha)numerical and in QR-code format. The (alpha)numerical credentials can also be found on the back side of the EasyControl thermostat. Fill in your credentials by using the QR-code scanner on the EasyControl app or type in your credentials manually .
Smartphone and platform
- Apple ≥ iOS9.
- Android ≥ 4.4 (4.4 Kitkat, 5.0-5.1 Lollipop, 6.0 Marshmallow, 7.0 Nougat, 8.0 Android O).
Your Android smart device does not meet the minimum specifications.
No, nor is this planned.
If the smartphone is not protected, someone else can operate it if the ‘automatic login’ is activated in the EasyControl app. To prevent this, don’t use ‘Automatic login’. If you lost your smartphone with limited protection, you can reset your thermostat password on another connected device. If only one smart device is used, you can set your EasyControl back to factory settings using a paper clip (see installation and operation manual).
Yes, it works without any problems.
Yes, but a number of technical and country-specific conditions must be met.
- Technical conditions:
- It needs to be a compatible appliance.
- A Wi-Fi connection needs to be available.
- EasyControl’s outside temperature information is only for your home country. This means that the correct outside temperature from the internet cannot be guaranteed, meaning the Weather-Dependent Control feature may not work abroad. To ensure that the correct outdoor temperature is detected, install a wired outdoor sensor. Please consult the installation manual for your boiler.
The EasyControl app defines the time zone based on the location of the thermostat. You can set a new time zone by changing your location.
No, it is not necessary for manual operation. For operation via your smart device, it is necessary. The reason for this is;
- The installer installs a new appliance and connects EasyControl to it. He or she can set the boiler to manual operation (without a Wi-Fi connection). The installation is now ready. Similar to other thermostats.
- When you – as a user – come home in the evening, you can set EasyControl up yourself:
- Enter your network’s Wi-Fi code into the EasyControl.
- Download the EasyControl app from the AppStore or Google Play.
- The EasyControl app helps you to set up the product through the on boarding wizard.
- Enter your credentials into the EasyControl app by scanning the QR code on the sticker on the front cover of the quick reference guide.
- Set your own password in the EasyControl app.
EasyControl is now ready for use!
Check the following summary or contact us
- Have you entered your EasyControl serial number and access code correctly?
- Have you entered your EasyControl app password correctly? The app reports if the incorrect password is used.
- Is the EasyControl connected to the Wi-Fi network?
- Is the Wi-Fi network connected to the internet?
- Execute a soft reset: remove EasyControl from the black plate, wait 10 seconds and place it back again.
- The router has an incorrect IP address assigned to EasyControl. Log in to the router via e.g.http://192.168.1.1 and enter the username and password (these are on the router's sticker). Reset the router software. New IP addresses are assigned.
No, the EasyControl just keeps working. If there is no internet, there is also no internet time meaning the clock program could deviate in the long run without synchronisation. In that case, it’s wise to open the app on the smart device so the EasyControl can automatically adopt the time on the device.
If your router's Wi-Fi signal is not strong enough to connect EasyControl, you can improve it with a Wi-Fi extender/repeater.
- DHCP available and enabled
- WEP-128, WPA or WPA2 encryption
- SSID not hidden
Step 1: Remove the old router.
Step 2: Insert the new router and ensure 230 V supply.
Step 3: Execute a soft reset: remove EasyControl from the ground plate.
Step 4: Wait 10 seconds.
Step 5: Place EasyControl back onto the ground plate.
Step 6: The display will then show:
- √ - connected with your appliance
- All Wi-Fi networks found are displayed.
- Select the correct Wi-Fi network.
- Press OK.
- If the Wi-Fi network is password protected, enter the password.
- Confirm password with OK.
- √ - connected to Wi-Fi
- √ - connected to Bosch XMPP-server
EasyControl is ready to use.
Some routers have a hide function. That makes them invisible. In order to connect to the router, the hide function must be temporarily disabled. The router name will then appear. Now you can select the Wi-Fi network. After the Wi-Fi connection is made, the hide function can be activated again.
The MAC address is indicated on the sticker on the front of the quick reference guide. A MAC address is the address of EasyControl used in the TCP/IP protocol, which the EasyControl uses to communicate with the router and the server.
According to the standard guidelines, there are 2 characters that cannot be used in passwords, namely "$" and "!". There are routers on the market that do not comply with this directive. Therefore EasyControl deviates from the directive and supports "!" in passwords.
Tests have been performed with no problems.
EasyControl cannot work with a frequency of 5 GHz. However, such routers usually offer the ability to work with the normal 2.4 GHz frequency as many Wi-Fi devices operate at 2.4 GHz.
The following may provide a solution:
- Set the Wi-Fi channel to the least-used channel (download free ‘Wi-Fi Analyser’ app in Google Play to scan the area)
- Deactivate hotspots
- Enable DHCP
- Select WPA2/PSK encryption
- Make SSID visible
- Add MAC address as trusted devices on the router
- Open port 5222 and 5223. If you have a smartphone that connects to the same Wi-Fi network and you can send WhatsApp messages, these ports will be open and cannot be the cause of the problem.
- Shut down the router for at least 5 minutes for a reset
- Reset the router and set it back to factory settings
- Unlock ICMP protocol with UBEE Ziggo routers? Contact our Customer Service if UBEE Ziggo router is causing connection problems with EasyControl.
- Open port 5580
Channels 1, 6, or 11 are the best Wi-Fi channels because they do not overlap if there are multiple wireless networks. In that case, choose the channel that is used the least for the strongest connection. We receive positive feedback from users who have changed their Wi-Fi channel. Usually they are automatically set to 1 or 13. Often it's worth changing it to 5 or 6, which will make your entire network faster and more stable.
You can try the following:
- Set the Wi-Fi channel to a free channel between 1-11 (EasyControl does not recognize channels higher than 11) (Some boxes such as the Xperia Box go beyond 11 channels);
- Select WPA2/PSK password encryption;
- Select 802.11 b/g/n at 2.4 GHz;
- If this does not give the desired result, reset the router to factory settings to reset the values above.
One advantage of the EasyControl is that data is not stored on the cloud. Everything is stored on the EasyControl thermostat itself. If you remove your EasyControl from its ground plate, you have your data in your hand. You and your fellow users are the owners of your boiler data. When you use extra services (e.g. Bosch HomeCom Pro, IFTTT, Amazon Alexa / Echo) you share information with Third Parties.
Through the EasyControl app, you can allow your installer to view the data on your thermostat for a set period of time and, if necessary, change the settings. You can end your installer's access immediately at any time.
Everyone is able to change the settings on the thermostat. The EasyControl app displays all current thermostat settings.
Bosch only stores the personal information needed to register your product for warranty, warranty and maintenance work, and servicing purposes.
All data required for the proper functioning of this product is stored locally in the product itself. When using the app, all data is stored on your mobile device. Only you can view it and change it with your personal access code.
Bosch has no access to your information
Bosch can see if your product is online but cannot gain access to your information. If necessary, you can authorise Bosch to gain temporary access to your product. The temporary access can be revoked at any time by turning it off in the app.
When changing your password, make sure you notify all the other EasyControl users of the new password.
The product software updates automatically. All data requested by your product for the updates will be sent in encrypted form. The coordinating and sending of data uses a secure server.
Weather information is taken from the Weather Company (IBM).
By using this product after purchase (and by installing and using the app) you are deemed to accept all the above. If you have any objection to the storage and use of your personal information as described above, you must notify us in writing. We will then delete that data we hold about you.
The EasyControl is not susceptible to viruses.
The EasyControl stores all data locally in the EasyControl itself.
Users create a Bosch account only once and register all Bosch products to that account. Additional services, like third party connections (e.g. IFTTT) can be used too.
Service & Support
Support – General
EasyControl’s consumption (display out) is approximately 0.5 W.
Your boiler is no longer controlled and therefore the heating will not work. In the event of frost, there will be some heating because every Worcester Bosch boiler has frost protection. The frost protection switches the boiler on when the boiler water temperature of 7 °C and off at a boiler water temperature reaches 17 °C.
The stolen thermostat must be replaced.
You probably have the RCC module connected which was required with your previous thermostat.
Support – Temperature
- Not well balanced
- Built-in radiators/curtains over it
- Underfloor heating
- Learning curve immediately after installation. The ‘optimum start’ still needs to be tuned. After the first week, large temperature differences will have been been averaged.
- Are the slots in the thermostat itself contaminated?
- Is there an airflow through the junction box?
- Is there any direct sunlight on the EasyControl?
- Are there any heat sources that affect the EasyControl?
- Is the EasyControl covered?
The boiler modulates. The device burns at low load and then achieves the highest efficiency. It's cheaper to let the device burn than start anew every time. If optimum start is active, the thermostat shows a flame symbol. The boiler is active for heating to reach the desired temperature as defined in the clock program.
Yes, you can. You can increase ordecrease the temperature shown via the app by 2 °C in 0.5 °C increments.
Support – Warranty
The default warranty period is 2 years for manufacturing errors. Bosch guarantees the EasyControl will be delivered and comply with the usual requirements and standards.
Support – eService
If you have entered your installer’s data (company/installer name, email, phone number, etc.) then the email is sent to his or her e-mail address.
The email contains the following information (see template below):
Dear Company, Installer name
There appears to be a problem with my appliance:
Appliance type: Appliance type
Appliance status: Status of appliance including error and code/s
Appliance maintenance request: Depending on the above
Complaint description: Your description of the problem
Can you please contact me for an appointment?
This message is automatically generated and sent by the EasyControl.
Accessories - Smart Watch
Support of Smart Watches (iOS and Android) will be introduced at a later date.
IFTTT is a service you can gain access to via the internet as well as through the IFTTT app. A separate IFTTT (if this, then that) channel will be created. The feature will be released at a later date.
Amazon Echo is one of the most popular user-friendly digital assistants. The EasyControl will be able to connect to digital assistants at a later date.
Smart Radiator Thermostat - Electronic Thermostatic Radiator Valve (Smart TRV)
If you are using the Smart Radiator Thermostats from Bosch in combination with low temperature radiators, you need to define a high set point so the valves do not close during high room temperatures. The maximum set point of Smart TRV is 30°C.
18 smart TRV’s can be installed in 24 separate zones.
We recommend you install a smart TRV in every room, but at a minimum one smart TRV must be installed in the same zone as your EasyControl.
Currently only the Worcester Greenstar GR 8700iW Style wall hung appliance is compatible with the Wireless Bosch Easy Control (including EasyControl Table Stand and EasyControl ‘Control-Key’).
EasyControl has been designed to be a wireless and portable solution; in addition, it requires a minimum power level that cannot be provided by conventional batteries. This provides a continuous WiFI and RF connection.
Currently the Wireless Bosch EasyControl is only compatible with the Worcester Greenstar GR 8700iW Style wall hung appliance and none other – however there are plans in the future for boilers to be compatible with the Wireless Bosch EasyControl.
Yes, documentation will be updated and will be published on the EasyControl microsite
To support the wireless functions the EasyControl needs to have (min.) FW version 2.0 and version App 2.0.
EasyControl must be connected to a WiFi network in order to perform the update. This can take up to 24 hours but the user can force the update via the app. Please note that if the current version of the device is older than version 1.4, it is necessary to first connect the EasyControl to an EMS 1.0 device to force the update via the APP.
Control-Key Currently only the Wireless Bosch EasyControl with the Key slot is compatible and tested with the EasyControl and the EasyControl ‘Control-Key’.
The Control-Key is powered from the appliance. There is no need to have an additional power supply.
This separate power supply can be used in case you wish to mount the EasyControl on the wall instead of on the Table Stand. Before installing the EasyControl on the wall it is recommended to test the RF signal strength from that location to the boiler.
The signal strength can be verified via the EasyControl App under the Settings>Devices menu. It is recommended that you look for a location with a maximum signal (3 bars).
