■
[3-02] Status: defines whether temperatures above 60°C can be
selected (1) or not (0).
INFORMATION
■
The maximum
temperature by heat pump operation is limited to
60°C. A higher temperature set point is only
possible by electric booster heater operation.
■
When this field setting is not activated, the
booster heater will still work if the ambient
temperature drops below the value set in [7-04].
This is the backup mode of the domestic hot
water heat pump.
■
[3-03] Status: defines whether the heat up can continue (1) or
not (0) when the requested temperature set point is not reached
during the programmed schedule timer operation. The p icon is
blinking in case the heat up can not continue ([3-03]=0).
In case the reheat function is enabled, the p icon will stop
blinking when the reheat operation has finished.

[6-00] and [6-01]: The 'DT (temperature difference) for heat pump
domestic water heating mode' field settings determine the
temperatures at which heating of the domestic hot water by the heat
pump will be started (i.e., the heat pump ON temperature) and
stopped (i.e., the heat pump OFF temperature).
When the domestic hot water temperature drops below the heat
pump ON temperature (T
HP ON
the heat pump will be started. As soon as the domestic hot water
temperature reaches the heat pump OFF temperature (T
the user set point temperature (T
by the heat pump will be stopped.
The heat pump OFF temperature, and the heat pump ON
temperature, and its relation with field settings [6-00] and [6-01] are
explained in the illustration below.
