Note
In summer mode and in exclusive DHW mode, the "OUT-
SIDE TEMP MIN CYC" parameter will not be taken into
account. The circulation pump runs as often as set in the
"MINIMUM CYCLES" parameter. If the outside temperature
falls below 4°C, the circulation pump runs in DHW mode
as often as set in the "MAXIMUM CYCLES" parameter.
In manual mode, the circulation pump runs as often as
set in parameter "MAXIMUM CYCLES" (P55).
In cooling mode the pump runs under room temperature-depend-
ent control.
 CONDENSATE PUMP (NO FUNCTION)
 RUN-ON SWITCH
This parameter has no function for this appliance.
 DEFROST RUN-ON MAX
This parameter has no function for this appliance.
 EMERGENCY MODE AUTO
When this parameter is activated, emergency mode will be acti-
vated if the compressor is disabled as a result of a fault.
 POWER-OFF
With the "POWER-OFF" parameter the effect of the power input on
the blocking of individual heat sources can be selected.
Option Function
0 No blocking
1 The heat pump is blocked. The electric emergency/booster heater is
blocked above the dual mode point for heating. After restarting, the
electric emergency/booster heater remains blocked for a certain
time. For this purpose, a restart time is set in the “Compressor cy-
cling” parameter. The electric emergency/booster heater for DHW
heating is started after the saved delay time stored in the "Booster
timeout" parameter has expired.
2 The heat pump is blocked. The electric emergency/booster heater
is enabled for DHW heating after a delay time of 10minutes has
elapsed. The electric emergency/booster heater is blocked above
the dual mode point for heating.
3 The heat pump is blocked. The electric emergency/booster heater is
enabled for DHW heating and heating after a delay time of 10min-
utes has elapsed.
4 The electric emergency/booster heater is blocked.
5 Electric emergency/booster heater and heat pump are blocked.
