Display of store temperature(s) of the heating circuit
afterheating.
Display of the DHW afterheating store temperature.
Adjustment channel for night correction (night set back)
of the heating circuit. For the night correction function,
time frames (see below) can be adjusted. Within these
timeframes, the set flow temperature of the curve will
be decreased (set back) by the adjusted temperature
value.
Adjustment channel for the day correction function
of the heating circuit. The day correction function is
always active outside the 3 time frames of the night
correction function. The flow set temperature of the
curve will be decreased or increased by the adjusted
temperature value.
Adjustment channel for the admissible maximum flow
temperature of the heating circuit. If the maximum flow
temperature is exceeded, the heating circuit will be
switched off (the mixer will close).
The heating curve used by the controller can be incre-
ased or decreased to suit the building heating load as
shown in the family of curves below. Increasing this
value has the effect of raising the flow set temperature,
reducing the value will lower the flow set temperature.
Example:
Rated temperature of the radiator flow 60 °C at lowest
outdoor temperature -12 °C according to calculated heat
demands. The intersection is the steepness of 1.2, used
as the adjustment value.
Day Correction:
If the following situation occurs during day operation:
Hot weather Ž Interior rooms too cold, cold weather
Ž Interior rooms to hot, proceed as follows: reduce
the steepness of the curve gradually by 0.2 points and
increase the day correction by 2 °C to 4 °C. This process
can be repeated several times if necessary (different
corrections for each heating circuit possible). Day correc-
tion is the upward translation of the characteristic curve.
