[E] - Display unit information
This parameter allows for the display of a wide range of information about the interior heat pump unit (HPSU compact).
No settings can be made for this parameter.
– [E-00] Display software version (example: 23)
– [E-01] Display EEPROM version (example: 23)
– [E-02] Display model number or ID (example: "11")
– [E-03] Display the temperature of the liquid refrigerant
– [E-04] Display the water temperature on the inlet
[F] - Configuration of functions
This parameter allows you to make a wide range of settings for the interior heat pump unit (HPSU compact).
– [F-00] Operation of the circulation pump outside of [4-02] /[F-01]:
0 = Pump function switched off:
Î
The circulation pump becomes inactive when the external temperature increases above the value specified by [4-02] or
falls below the value specified by [F-01].
1 = Pump function switched on:
Î
The circulation pump can work at all external temperatures.
– [F-01] Permission for room cooling :
Determines the external temperature beyond which the room cooling is switched off.
– [F-02] Underfloor heating ON temperature:
Determines the external temperature beyond which the HPSU compact activates underfloor heating for the external unit to
avoid the formation of ice.
– [F-04] Functionality of the connection X14A (cannot be set).
The displays [E-03] and [E-04] are not refreshed continuously. The displays for the temperature data are not
refreshed unless you re-enter the first codes for the setting parameters to be defined at the installation site.
The settings made at the installation site for the operation of the circulation pump only relate to the logic of the
pump operation when the DIP switch SS2-3 is set to OFF.
– [F-03] Underfloor heating hysteresis:
Determines the difference between the values for the underfloor heating ON
temperature and the underfloor heating OFF temperature.
ON Underfloor heating switched on
OFF Underfloor heating switched off
