  • Page 4: A General Descriptions Of The Thermostat

    1. A GENERAL DESCRIPTIONS OF THE THERMOSTAT COMPUTHERM B300RF Wi-Fi Wi-Fi thermostat is a wireless switching de- vice that can be operated by a smartphone, tablet or computer via Internet, and we especially recommend it for controlling central heating systems but suitable for irrigation systems, garage doors, for remote control of doors and other electrical appliances and programmed also control.
  • Page 5 The portability of the thermostat offers the following advantages: • no need to lay a cable, which is especially advantageous when old build- ings are being modernized, • the optimal location of the device can be selected during operation, • it is also advantageous when you intend to locate the thermostat in different rooms in the course of the day (e.g.
  • Page 6 Multiple thermostats, even installed in different locations, can be registered and controlled by using the same user profile. A COMPUTHERM B300RF Wi-Fi thermostats can be used to control: • gas boilers • an existing heating/cooling system remotely • electric water heaters...

  • Page 7: Important Warnings And Safety Recommendations

    The simultaneous use of several COMPUTHERM room thermostats and one COMPUTHERM Q4Z zone controller provides the possibility for the thermo- stats to also control a pump or a zone valve in addition to starting the heater or cooler.
  • Page 8 • The thermostat was designed for business or household (not industrial) use, and can be used to control any electric device whose performance does not exceed 3.6 kW (loadability: max 30 V DC / 250 V AC; 16 A [4 A inductive]).
