Wi-Fi thermostat for radiator and underfloor heating systems

COMPUTHERM E280

The COMPUTHERM E280 and E300 thermostats can be used to control the device (e.g. boiler) connected to them and to check its current state using your smartphone or tablet via the Inter­net. With the help of these products the heating/cooling system of your flat, house or holiday home can be made controllable from any place and at any time. These products are especially useful when you do not use your flat or house according to a predefined schedule, you leave your home for an uncertain period of time during the heating season or you intend to use your holiday home during the heating season as well. The thermostats are especially suitable for controlling underfloor heating systems owing to the connectable floor temperature sensor. The thermostats have two potential free relays which switch simultaneously therefore they are able to control two independent apparatuses. The two parallel operating relays simply ensure that the thermostats can activate or turn on or off a pump and a zone valve, in addition to starting up the boiler. Thus, using several COMPUTHERM E280 and/or E300 type Wi-Fi thermostats, a heating system can be easily divided into zones without a separate zone control system.
The COMPUTHERM E300 Wi-Fi thermostat is a more advanced version of the COMPUTHERM E280 Wi-Fi thermostat, with black instead of white colour, glass screen and even more modern display.
