Using the EasyControl together with the Bosch Smart Radiator Thermostats enables you to set independent temperatures in the different rooms in your home.

EasyControl CT200 – smart control for heating and hot water
The EasyControl is a multizone internet-connected programmable smart thermostat for heating and hot water system control, which can be operated using this app.
Once installing this app, there is the option to run the app in demo mode, without access to the internet, an EasyControl or a compatible heating appliance to showcase the extensive features and simplicity of use. The EasyControl is compatible with multiple brands of appliances, e.g., Bosch, Nefit, Worcester, Junkers, elm Leblanc among others.

Individual temperature control
Witt the EasyControl it is possible to set up to 20 zones (or rooms), each with its individual schedule and set temperatures. This ensures you have the right comfort temperature in each zone and that each zone only heats when you want therefore saving energy. The control of the temperature in the individual zones requires the installation of the optional EasyControl's smart radiator thermostats.

Simple to use
The EasyControl intuitive operation and modern design ensures it is very simple to operate using either its built-in colour touch-screen or the app.
• Supplied with a pre-set schedules that can then be easily modified to fit your needs.
• The EasyControl features a ‘vacation mode’, requiring just a beginning and end date. You can also set up other type of events such a national holiday or a day at home.
• A quick installation guide is provided with each EasyControl. Additional information is available at the website: including the product manuals, a list of compatible appliances and helpful videos that provide further detail on specific functions.

Simply smarter
The EasyControl’s advanced programming enables it to have an ‘intelligent conversation’ with the appliance to take advantage of features which help improve energy efficiency, such as:
• Load and weather compensation which reduce the appliance water temperature to help further increase efficiency, while also increasing user comfort.
• Unlike other smart heating controls, the EasyControl can also control your domestic hot water settings, helping provide additional energy savings and comfort.
• Visual representation of energy usage data can help you easily identify where potential savings could be made.

Simply does not connect.

UPDATE: After pulling my hair out at the constant loss of connection, I called Worcester Bosch to see if they could help. Spoke to Saj (excellent). Seems the controls do not like the 5ghz WiFi channel, so you have to rename the 2.4ghz on your hub and connect the control to that channel only. Since I’ve done this, no drop outs and connection every time. Why only 4 stars? You still need two factor connection instead of Touch ID, and I’ve yet to use the programming part of the control. Overall happy.

We have now had this app and thermostat for nearly one week, and I would say the app connects 10% of the time. It constantly holds on the blue connect screen and then states it cannot connect. Also noticed that the thermostat drops the WiFi connection and shows a crossed globe. Can still use the thermostat at this point, so it is connected to the WiFi, but the app refuses to connect until I’ve turned the thermostat off and back on to reset the globe symbol.

Would send back if I still had the box. Very disappointed, and would have used another thermostat/control if I had known.

Don’t bother with this one until they’ve sorted out fundamental issues!

Not fit for purpose

Firstly. Where are all these one line positive reviews coming from? This app has gone up by a star and a half rating in three days...I have reported them for Apple to look at and I will be looking in to this further. One hopes a company like Bosch wouldn’t be buying reviews..!

Back to the app. We had a new boiler and the easy control stat and app installed last year. We had nothing but trouble with it, and being it happened when lockdown hit we couldn’t do anything. Heating used to come on by itself constantly, always due to lack of connection. Middle of the night during warm weather and we would be woken up by the heating. We tried moving the stat, moving the wifi, everything. In the end we had to switch the boiler off at the wall when not needed. When lockdown eased we spoke to Bosch who said they had never heard of any issues with it! Think your reviews here beg to differ! They sent an engineer out who said he had no idea about the technology, but replaced the unit in case it was faulty. Nope, same issue, heating on by itself and lost connection randomly. Had another (rude) engineer out who again said he wasn’t trained and couldn’t help...spent most of the visit taking personal calls. Finally scrapped the “easy” control system. Total stress, no support from Bosch whatsoever, and now looks like they have resorted to buying positive reviews to boost their product. What a shame.

Needs a written manual

I have just had a new boiler installed and along with this an Easy Control system and TRVs. The info coming with them is Ok, but the big problem is a written manual for this app. The app is an integral part of the system as without it you cannot get individual room info, add devices or set up heating schedules. Yes there is a demo but it is out of date, it is nothing more than a simulation, which could be useful if there was a manual! For example the demo has the facility to delete a heating time and set point, but the real-time app does not have this. The default schedule has 4 time points, 2 would be better. There is no information on locating the Easy Controller other than it should be in the room most often occupied and this room should also have a TRV in it, no explanation of what the set point on the Easy controller should be set to, should it be set as the highest set point on the system, should it be set to the same as the TRV in the chosen room? Then there is the nothing on Weather control other than contact your installer, that assumes your installer understands it ( they didn’t). If this was sorted I would be inclined to give another star or two.
