4.2.2 Parameter description
[0] - Access authority
If required, certain buttons on the main control unit (HPR1) can be made unavailable to the user.
Three stages of Access authority are defined (Default settings see tab. 4 -1). Setting the Access authority must be carried out
as follows:
• Check whether the HPSU compact runs in normal operation, if necessary activate normal operation.
• Change to the mode "Parameter setting" and there, select the parameter [0-00] (see chapter 4.2.1).
Î
The icon
and the current parameter code [0-00] are displayed on the user interface display.
• Use the
and
keys to select authorisation level 2 or 3.
– The factory setting is authorisation level 1.
– The authorisation level can only be changed in the following steps:
1 -> 2 or 2 -> 1
1 -> 3 or 3 -> 1
• Press the
key to save the selected authorisation level.
• Press key
to leave parameter setting.
Î
The system is in normal operation again.
• Press the

[1] - Weather-dependent set value regulation
The target settings in the parameter settings determine the specified values to be attained in weather-dependent operation.
If the "Weather-dependent set value regulation" is active, the flow temperature is determined automatically depending on the
outside temperature: Colder outside temperatures result in warmer water and vice versa. During "Weather-dependent set value
regulation", the user can adjust the target flow temperature by a maximum of 5 °C up or down.
The following setting options are available:
– [1-00] Lowest ambient temperature (Lo_A): Lowest outside temperature.
– [1-01] Highest ambient temperature (Hi_A): Highest outside temperature.
– [1-02] Target value at lowest ambient temperature:
Target temperature at water outlet of the interior heat pump unit (HPSU compact) if the outside temperature is equal to or
falls below the lowest ambient temperature (Lo_A).
– [1-03] Target value at highest ambient temperature:
Target temperature at water outlet of the interior heat pump unit (HPSU compact) if the outside temperature is equal to or
increases above the highest ambient temperature (Hi_A).
