Time programs Heating
The end user can choose from five
pre-defined time programs for heating
systems according to his wishes. If a
time programme is activated, the boiler
operates in the desired periods in order
to keep the room temperature at the
comfort temperature level. Outside
these periods, the boiler operates at a
reduced temperature level.
Alternatively, you can create your own
time programmes or adapt existing
programmes to your own requirements.
Heating curve Slope
The flow temperature set-point is
adjusted according to the measured
outside air temperature and the set
weather compensation curve.
Example: Weather compensation
curve 3.5 will provide a higher primary
flow temperature set-point at a given
outside air temperature than curve
1.0 The weather compensation curve
can be adjusted to suit the heat loss
characteristic of specific buildings.
Increase setting: Increases the flow
temperature, especially when the
outdoor temperature is cold.
Lower the setting: Reduces the flow
temperature, especially when the
outdoor temperature is cold.
Heating curve Parallel shift
If the ambient temperature is too hot
or too cold regardless of the outdoor
temperature, use the parallel shift to
adjust the curve.
Depending on the system conditions
(boiler settings during installation),
a setting range of ±7K (at low
temperature) or ±14K (at high
temperature) is possible.
