Setpoint shift control
This function enables the operator to adapt the condensing pressure or the outlet temperature to
specific operating conditions. All relevant values are set in the
Main menu

Setpoints


shifting.
This menu item is only displayed after a control has been selected (see also chapter 5.6.3
“
Setpoint shifting”)
The following control options are available:
Signal type:

Analogue 0 – 100 %
Options:

Off * Function deactivated.

Via terminal
