The thermostat ignition sensitivity can be
selected: ± 0.2°C (factory setting, recommended
for heating systems with radiator) or + 0/-0.2°C (this
setting is recommended for underoor heating).
This conguration represents the temperature
dierence between the adjusted value and the actual
temperature measured during the ignition process.
For example, if the factory setting is 20°C on the
thermostat, the device turns on the boiler at 19.8°C
or below this level and goes o at 20.2°C or above.
(Please refer to section 3.3 for the change of ignition
sensitivity from factory default of ± 0.2°C).
The thermostat is equipped with a pump protection
function which, in order to prevent the pump
from blocking, turns on the boiler for one minute
at 24 every day if the pump has not turned on in a
programmed way for more than 24 hours (for example
, outside the heating season). See the activation of the
pump protection function in Section 3.4.
