Status codes
Statuscode
Meaning
S.34 Heating mode: Frost pro-
tection
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.
S.100 Standby
There is no heat demand or cooling demand. Standby 0: Outdoor unit. Standby 1: Indoor unit
S.101 Heating: Compressor
shutdown
The heat demand is met, the demand is ended by the system control and the heat deficit is offset.
The compressor is switched off.
S.102 Heating: Compressor
blocked
The compressor is blocked for heating mode because the heat pump is outside of its operating limits.
S.103 Heating: Prerun
The start conditions for the compressor in heating mode are checked. Start the other actuators for
heating mode.
S.104 Heating: Compressor
active
The compressor works in order to meet the heat demand.
S.107 Heating: Overrun
The heat demand is met, the compressor is switched off. The pump and fan overrun.
S.111 Cooling: Compressor
shutdown
The cooling demand is met, the demand is ended by the system control. The compressor is switched
off.
S.112 Cooling: Compressor
blocked
The compressor is blocked for cooling mode because the heat pump is outside of its operating limits.
S.113 Cooling: Compressor
mode prerun
The start conditions for the compressor in cooling mode are checked. Start the other actuators for
cooling mode.
S.114 Cooling: Compressor
active
The compressor works in order to meet the cooling demand.
S.117 Cooling: Compressor
mode overrun
The cooling demand is met, the compressor is switched off. The pump and fan overrun.
S.125 Heating: Immersion
heater active
The immersion heater is used in heating mode.
S.132 Domestic hot water:
Compressor blocked
The compressor is blocked for domestic hot water mode because the heat pump is outside of the
operating limits.
S.133 Domestic hot water:
Prerun
The start conditions for the compressor in domestic hot water mode are checked. Start the other actu-
ators for domestic hot water mode.
S.134 Domestic hot water:
Compressor active
The compressor works in order to meet the domestic hot water demand.
S.135 Domestic hot water:
Immersion heater active
The immersion heater is used in domestic hot water mode.
S.137 Domestic hot water:
Overrun
The domestic hot water demand is met, the compressor is switched off. The pump and fan overrun.
S.141 Heating: Immersion
heater shutdown
The heat demand is met, the immersion heater is switched off.
S.142 Heating: Immersion
heater blocked
The immersion heater is blocked for heating mode.
S.151 Domestic hot water:
Immersion heater shutdown
The domestic hot water demand is met, the immersion heater is switched off.
S.152 Domestic hot water:
Immersion heater blocked
The immersion heater is blocked for domestic hot water mode.
S.173 Anti-cycling time for
the energy supply company
The mains voltage supply is interrupted by the energy supply company. The maximum anti-cycling
time is set in the configuration.
S.202 Check programme: Pur-
ging of building circuit active
The building circuit pump is actuated in cyclical intervals, alternately in heating mode and domestic
hot water mode.
S.203 Actuator test active
The sensor and actuator test is currently operating.
S.212 Connection fault: Con-
trol not recognised
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.
