The heat pump is switched off because the operating mode, 2nd heat generator (HG2), was
selected. Heat generation is provided by the 2nd heat generator.
Flow rate monitoring of the heating water takes place before evaporator defrosting is started. This
applies to air-to-water heat pumps only. This process lasts a maximum of 4 minutes.
The heat pump defrosts the evaporator. This process lasts a maximum of 8 minutes.
The maximum flow temperature was overshot. Once the temperature drops, the HP will start again
automatically (HT HP only).
Switching to and from the cooling operating mode activates a time delay of 5 minutes. The heat
pump remains switched off during this period.
Despite a pending request, the chiller is unable to cool because frost protection was activated.
This state is ended automatically.
Despite a pending request, the chiller is unable to cool because the current flow temperature is
under the operating limit. This state is ended automatically.
Despite a pending request, the chiller is unable to cool because the dew point monitor was
activated (external input). This state is ended automatically.
Despite a pending request, the chiller is unable to cool because the dew point calculated from the
sensor values from the room climate control stations was undershot. This state is ended
automatically.
The heat pump operates in passive cooling and no requests are pending.
