Computherm Q7RF Operating Instructions Manual page 3

The effective range of the transmitter incorporated in the thermostat is
approximately 50m in open terrain. This distance may become considerably
shorter within a building, especially when a metal structure, reinforced
concrete or adobe wall stands in the way of radio waves.
The switching sensitivity of the thermostat can be set to ±0.1°C, ±0.2°C
(default setting) or ±0.3°C. This figure means the temperature difference
between the adjusted value and the actual temperature measured during
the switching process. In case of the ±0.2°C switching sensitivity and
heating mode for example, if the set temperature is 20°C, then the device
switches the boiler on at 19.8°C or below, and switches it off at 20.2°C or
above. Please refer to Section 2.4 for the modification of the factory default
switching sensitivity of ±0.2°C.
The thermostat is equipped with a pump protection function, which,
to prevent the pump from sticking, switches on the boiler for a one minute
period at 12:00 p.m. every day if the pump has not been switched on in
a programmed manner for more than 24 hours (e.g. outside the heating
season). See the activation of the pump protection function in Section 2.5.
This wireless (radio-frequency) thermostat can also be easily extended with
the COMPUTHERM Q1RX socket if needed, with which the thermostat is
able to control boilers or any other electrical devices operating on 230V
(50Hz; max. 10A) (e.g. fan heaters, pumps, zone valves, etc.) according to
the room temperature.
