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 o multiple times in an hour’s time except at
low outside temperatures (e.g. -10 °C), since the frequent on
and o switches of the boiler reduce its eciency 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 sensitivity for heating
systems with low thermal inertia (e.g. at panel radiators).
To change the switching sensitivity, rst press the “SET”
button to go to the main screen. Then press the “DAY” and
“COPY” buttons one after the other. Following this, select the
desired switching sensitivity using the large and
buttons. The notices “ ”, “ ” and “ ” indicate ±0.1 °C,
±0.2 °C and ±0.3 °C, respectively. Finally, conrm the setting
