Pump speed max
(883, 1183, 1483) Using this function the maximum speed for the heating circuit pump can be
specified.
Curve readj at 50% speed
(888, 1188, 1488) Correction of the flow setpoint with reduction of the pump speed by 50%. The
correction is calculated from the difference from the flow setpoint according to
the heating curve and current room setpoint.
Flow setp readj speed ctrl
(890, 1190, 1490) Here it can be specified whether the calculated flow setpoint correction is inclu-
ded in the temperature request or not.
-
No
: the temperature request remains unchanged. The calculated correction val-
ue was is not added.
- Yes : the temperature request includes the flow setpoint correction.
Operating level changeover
(898, 1198, 1498) Using an external timer above the entrances Hx it can be selected in which oper-
ating level the heating circuit is switched into.
-
Frost Protection :
- Reduced :
- Comfort :
Optg mode changeover
(900, 1200, 1500) In case of external changeover of the operating mode per Hx it can be selected, if
in automatic mode changeover will be carried out from nominal comfort value to
the frost protection value or the reduced nominal value.
8.11 DHW
Nominal setpoint
(1610) Setting the DHW nominal setpoint.
Reduced setpoint
(1612) The DHW reduced setpoint is set under prog. no. 1612.
Release
(1620) - 24h/day : The DHW temperature will be continuously controlled to the nominal
drinking water temperature value independent from the time switching pro-
grammes.
- Time programs HCs : The DHW temperature will be switched over between the
nominal DHW temperature value and the reduced nominal DHW temperature
value depending on the time switching programs. Every time, the switching-on
time will be moved forward.
