Is tado° compatible with my boiler?

tado° works with most boilers. The only requirement for tado° to work with your boiler is that it communicates in a language that tado° can understand and process.

The most common ways in which thermostats communicate with boilers are through simple relay (on/off) connections or through digital communication systems.

Relay (on/off) heating systems

A relay (on/off) connection works like a normal electric switch. When there is a call for heat, the electric circuit closes to switch on heating. And when the desired temperature is reached, the circuit opens to switch off the heating. 

tado° is compatible with almost all boilers that support relay connections.

The Smart Thermostat has one relay connection which can be used to control heating. The Extension Kit has two relay connections, one of which controls heating. The second relay connection is most often used to control hot water, but can also be used to control a pump or a second heating stage.

Digital heating systems

Apart from relay heating systems, there are digital systems that can modulate the amount of heat supplied by the boiler. If there is a request for a minor increase in temperature, the room thermostat can power the boiler accordingly to meet that specific request rather than firing at full capacity.

Other than modulating the temperature, some digital heating systems also allow two-way communication between room thermostats and boilers. This means that more complex information like the current temperature, the set temperature, and error codes can be transferred between these devices.

tado° is compatible with OpenTherm boilers. It can control heating and hot water by working with most other boilers that support digital communication*. To check if tado° can control your digital heating system, please refer to the table below:
