With the help of the COMPUTHERM E280 type Wi-Fi thermostat, you can control the device connected to the thermostat (eg gas boiler) via the Internet and check its operation with the help of your mobile phone and tablet. It can be easily connected to any gas boiler with a two-wire room thermostat connection point, as well as to any air conditioner or other electrical appliance, regardless of whether they have a 24 V or 230 V control circuit.

By using the product, the heating of your apartment, house or holiday home can be controlled anytime and from anywhere. The thermostat is especially ideal if:

  • You do not use your apartment or house according to a pre-determined agenda,
  • Leaves home for an indefinite period during the heating season,
  • You also want to use your resort during the heating season.

The thermostat is particularly suitable for controlling underfloor heating systems thanks to the connectable floor temperature sensor. The product has two potential-free relays that switch at the same time, so up to two completely independent products can be controlled with it. The relays in the device provide an easy way to e.g. in addition to starting the boiler, the thermostat also activates and switches on a pump or a zone valve. Thus, with the help of several COMPUTHERM E280 Wi-Fi thermostats, it is easy to divide a heating system into zones without using a separate zone controller.
