The current operating status of the heat pump system can be
read from the LC display.

9.1 Normal Operating Statuses

The display shows both normal operating statuses and those that
are required by utility companies or due to safety functions of the
E-13
Heat pump does not operate because there is no request for heating pending.
Heat pump operates in heating operation
Heat pump operates with active cooling
Heat pump operates for DHW preparation and heats the hot water cylinder
Heat pump operates and heats the swimming pool water
Heat pump and 2nd heat generator operate in heating operation
Heat pump and 2nd heat generator operate and heat the swimming pool water
Heat pump and 2nd heat generator operate in DHW heating operation and heat the hot water
cylinder
After expiry of the minimum pause time, the heat pump will start in order to meet the heating
request that is pending. The minimum pause time protects the heat pump and can last up to 5
minutes.
After expiry of the switch cycle block, the heat pump will start in order to meet the heating request
that is pending. The switch cycle block is required by utility companies and can last up to 20
minutes. A maximum of 3 switch-ons per hour are permissible.
After expiry of the switch-on delay for the line load, the heat pump will start in order to meet the
heating request that is pending. The switch-on delay for the line load is required by utility
companies after the voltage is recovered or after a utility block. It can last up to 200 seconds.
The heat pump starts after expiry of the utility company shut-off time. The utility company shut-off
time is specified by the utility company and lasts up to two hours depending on the utility company.
Activation or deactivation is carried out by the utility company.
The heat pump was switched off by an external utility blocking signal on input ID4.
The heat pump starts after completion of the primary pump forerun. This can last up to 3 minutes
(safety function).
The heat pump was switched off because the low pressure limit was reached. The heat pump will
switch on again automatically. The 2nd heat generator (HG2) undertakes the supply of heat until
the heat pump switches on again automatically.
The heat pump was switched off because the low pressure limit was reached. The heat pump will
switch on again automatically. The 2nd heat generator (HG2) undertakes the supply of heat until
the heat pump switches on again automatically.
The heat pump was switched off because the lower operating limit was reached. The heat pump
will switch on again automatically as soon as the heat source temperature has reached a sufficient
level (safety function).
The heat pump was switched off because the high pressure limit was reached. It will switch on
again automatically (high pressure safety program).
The heat pump cannot start because of the operating temperature limit. The external air
temperature is less than –15 °C or –20 °C, or higher than 35 °C (safety function). Or the heat pump
was blocked by the "Bivalent-alternative" setting, because the external temperature is lower than
the limit temperature.
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 the evaporator is defrosted. 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 return temperature was overshot. Once the temperature drops, the HP will start
again automatically.
Switching to and from the cooling operating mode activates a time delay of 5 minutes. The heat
pump remains switched off during this period.
