Raising the reduced room temperature
During operation at reduced room temperature, the
reduced set room temperature can be automatically
raised subject to the outside temperature. The temper-
ature is raised in accordance with the selected heating
curve, and no higher than the standard set room tem-
perature.
The outside temperature limits for the start and end of
temperature raising can be set in coding addresses
"F8" and "F9" in the
"Heating circuit"
group.

Reducing the heat-up time
During the transition from operation at reduced room
temperature to operation at standard room tempera-
ture, the flow temperature will be raised in accordance
with the selected heating curve. The flow temperature
increase can be raised automatically.
The value and duration of the additional increase in set
flow temperature can be set in coding addresses "FA"
and "Fb" in the
"Heating circuit"
group.
