The normative states the installation must be executed only by specialized technicians and without power supply. The installation is very simple though, you just need to connect the two cables managing the opening and closure of your heating system’s relay following the same connections of the thermostat you replace (NC – NO). If the old thermostat had cables to connected to 230V power supply, you need to isolate them.

Typically, modulating thermostats, in order to communicate with the heating’s boiler, only work with same brand boilers.


No. Tyrrell Smart Home can manage up to 12 independent zones already equipped with an electric control.

Our thermostat will replace any existing thermostats to manage the whole heating system. It does not manage single radiators.

Our thermostat is an intelligent chronotermostat with all the functions of a traditional programmable thermostat, to which we added smart features such as remote management, programming based on the inhabitants’ distance from home and the possibility to monitor heating’s functioning, described by a graph.


To make Tyrrell Smart Home a “universal” thermostat, the creators couldn’t make it communicate additional information to boilers, because every boiler talks a proprietary language to thermostats of the same brand.
Replacing your current thermostat with ours means losing this functionality.
