COMPUTHERM E800RF Wi-Fi thermostat

COMPUTHERM E800RF Wi-Fi thermostat

The COMPUTHERM E800RF type Wi-Fi thermostat is an 8-zone wireless switching device that can be controlled via the Internet from a smartphone or tablet, and is primarily recommended for controlling heating and cooling systems, which is suitable for controlling the vast majority of boilers and air conditioners on the market in Hungary. 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 device, regardless of whether they have a 24 V or 230 V control circuit.

The basic package of the device includes two COMPUTHERM E800RF (TX) thermostats and a receiver. If required, the equipment can be expanded with six additional COMPUTHERM E800RF (TX) thermostats.

The COMPUTHERM E800RF Wi-Fi thermostat can be used:

  • for controlling gas boilers
  • for remote control of an existing heating/cooling system
  • for controlling electric boilers
  • for controlling solar systems
  • to control certain groups of other electrical devices

The device consists of two units. One is the thermostat (transmitter), the other is the receiver, which controls the boiler. There is a wireless (radio-frequency) connection between the two units, so there is no need to build a line, which is especially beneficial when modernizing old buildings.

It is important to know that the thermostat unit requires a constant power supply (micro USB 5 V DC, 1 A) due to continuous Wi-Fi communication. The adapter and cable are included in the package.

By using this product, the heating of your apartment, house or holiday home  can be controlled anytime and from anywhere .

The thermostat is especially ideal if:

  • does not use your apartment or house according to a predetermined schedule, 
  • leaves home for an indefinite period of time during the heating season, 
  • you also want to use your holiday home during the heating season.

By using several COMPUTHERM room thermostats ( E800RF (TX) ), it is easy to divide a heating system into zones , thanks to which the heating of each room can be controlled separately, thereby greatly increasing comfort . Furthermore, the division of the heating system into zones greatly contributes to the reduction of energy costs , as only the rooms that need it are always heated.
