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 adjusted 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 3.4.
