FA ROTEX HPSU compact 308 - 02/2012
[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
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.
[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.
The customer settings for operation of the circulation pump are only relevant to the pump operation logic if DIP

.
– [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-03] Underfloor heating hysteresis:
Determines the difference between the values for the underfloor heating ON
temperature and the underfloor heating OFF temperature.
