Meaning
If the measured outdoor temperature falls below XX °C, the temperature of the heating circuit's flow
and return is monitored. If the temperature difference exceeds the set value, the pump and com-
pressor are started without a heat demand.
There is no heat demand or cooling demand. Standby 0: Outdoor unit. Standby 1: Indoor unit
The heat demand is met, the demand is ended by the system control and the heat deficit is offset.
The compressor is switched off.
The compressor is blocked for heating mode because the heat pump is outside of its operating limits.
The start conditions for the compressor in heating mode are checked. Start the other actuators for
heating mode.
The compressor works in order to meet the heat demand.
The heat demand is met, the compressor is switched off. The pump and fan overrun.
The cooling demand is met, the demand is ended by the system control. The compressor is switched
off.
The compressor is blocked for cooling mode because the heat pump is outside of its operating limits.
The start conditions for the compressor in cooling mode are checked. Start the other actuators for
cooling mode.
The compressor works in order to meet the cooling demand.
The cooling demand is met, the compressor is switched off. The pump and fan overrun.
The immersion heater is used in heating mode.
The compressor is blocked for domestic hot water mode because the heat pump is outside of the
operating limits.
The start conditions for the compressor in domestic hot water mode are checked. Start the other actu-
ators for domestic hot water mode.
The compressor works in order to meet the domestic hot water demand.
The immersion heater is used in domestic hot water mode.
The domestic hot water demand is met, the compressor is switched off. The pump and fan overrun.
The heat demand is met, the immersion heater is switched off.
The immersion heater is blocked for heating mode.
The domestic hot water demand is met, the immersion heater is switched off.
The immersion heater is blocked for domestic hot water mode.
The mains voltage supply is interrupted by the energy supply company. The maximum anti-cycling
time is set in the configuration.
The building circuit pump is actuated in cyclical intervals, alternately in heating mode and domestic
hot water mode.
The sensor and actuator test is currently operating.
System control was previously detected but the connection is broken. Check the eBUS connection to
the system control. It can only be operated with the heat pump's additional functions.
