The COMPUTHERM E400RF Wi-Fi thermostat is a wireless switchable device that can be controlled via smartphone and tablet via the Internet, and is primarily recommended for controlling heating and cooling systems. 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.
The COMPUTHERM E400RF Wi-Fi thermostat can be used:
  • to control gas boilers
  • for remote control of an existing heating / cooling system
  • to control electric boilers
  • to control solar systems
  • to control certain groups of other electrical appliances
The device consists of two units. One is the thermostat (transmitter unit), the other is the receiver unit, which controls the boiler. There is a wireless (radio frequency) connection between the two units, so there is no need to build a wire, which is especially beneficial when upgrading old buildings.

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 simultaneous use of several COMPUTHERM room thermostats and one COMPUTHERM Q4Z zone controller provides the possibility to e.g. in addition to starting the boiler, a given thermostat must also control a pump or a zone valve. In this way, it is easy to divide a heating system into zones, thanks to which the heating of each room can be controlled separately, thus greatly increasing comfort. Furthermore, the zoning of the heating system also contributes greatly to the reduction of energy costs, as only the rooms where it is needed are always heated.
