Anti freezing
Activating or deactivating the anti-freezing function while the device is switched off.
Base pan heater
Choice whether an optional base pan heater is connected or not and its use type:
Type A - The base pan heater is only switched on during defrost mode.
Type B -The base pan heater is switched on at temperatures of 5 °C and below.
Alternative outdoor sensor
Selection of an alternative outdoor temperature sensor.
Bivalent heating
Selection of a bivalent heating system, so that an additional heat source, e.g. a heating boiler, can heat up the buff-
ertankandthedomestichotwatertank,iftheheatpumpcapacityisnotsufcientatloweroutsidetemperatures.
The bivalent function can be operated in alternative mode (heat pump and heating boiler are operated alternately)
or in parallel mode (heat pump and heating boiler are operated simultaneously) or be set in advanced parallel mode
(heat pump is operated and heating boiler is activated for buffer tank and/or domestic hot water, depending on the
setting options activated for switching behaviour).
Circulating liquid
Selection as to whether water or glycol is being used as the heating medium.
Pump maximum speed (pump control)
  Settingofowrateandmaximumduty,andswitchingthepumpon/off.
Pump down
Switching the pump-down mode on
Dry concrete

phase).
Force heater

models.
System Monitoring
Energy monitor
Display of a diagram with current or recorded data (Present / Historical chart) with regard to energy consumption,
generation or COP. It is possible to have recording intervals of 1 day, 1 month or 1 year. The energy consumption
for heating mode, optionally cooling mode and hot water mode as well as total energy consumption is recorded.
System information
Display of all current system information, i.e. inlet water temperature, outlet water temperature, zone 1 temperature,
zone 2 temperature, domestic hot water tank temperature, buffer tank temperature, solar circuit temperature, pool
temperature,compressorfrequencyandpumpowrate.NotallitemsavailableforHgenerationmodels.
Error history
  Displayofthelastoccurringerrorcodeinreversechronologicalorder(i.e.thelastsignalrst).
Compressor
Display of technical data on compressor operation, e.g. current compressor frequency, number of starts and total
operating time.
Backup heater
Display of the operating hours of the backup heater for space heating/domestic hot water mode respectively.
