The effective range of the transmitter incorporated in the thermostat is
approximately 50 m in open terrain. This distance may become considerably
shorter within a building, especially when a metal structure or a reinforced
concrete wall stands in the way of radio waves.
The switching sensitivity of the thermostat can be selected: ±0.2°C
(factory default setting, recommended for radiator-based heating systems) or
+0/-0.2°C (this setting is recommended for underfloor heating). This figure
means the temperature difference between the reference value and the actual
temperature measured during the switching process. For example, if the
factory default setting is 20°C on the thermostat then the device switches on
the boiler at 19.8°C or below this level and switches it off at 20.2°C or above.
(Please refer to Section 2.3 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 2.4.
If the power supply to the receiver is interrupted for any reason (e.g. power
outage), the boiler also stops working. Shortly after the power outage the device
resumes its operation according to the program without any intervention.
