The effective range of the transmitter incorporated in the thermostat is approxi-
mately 50m in open terrain. This distance may become considerably shorter
within a building, especially when a metal structure, reinforced concrete or ado-
be 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 pro-
cess. 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 pre-
vent 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
.
