3.4 Setting the switching sensitivity (accuracy)
The switching sensitivity means the temperature difference between
the adjusted value and the actual temperature measured during the
switching process. A smaller switching sensitivity results in steadier
room temperature and therefore in higher comfort. The heat loss
of the room (building) does not depend on the switching sensitivity.
If higher comfort is needed, the switching sensitivity should be
set so that it provides a steadier room temperature. On the other
hand, please also take into account that the boiler should not switch
on and off multiple times in an hour’s time except at low outside
temperatures (e.g. -10°C), since the frequent on and off switches
of the boiler reduce its efciency and hence increases the gas
consumption. We recommend using the ±0.1°C switching sensitivity
for heating systems with high thermal inertia (e.g. underoor
heating), the ±0.2°C (factory default setting) and ±0.3°C switching
