Primary control may be enabled or disabled.
If primary is disabled the unit no longer produces cooling or
Enables the
heating on the primary side (the primary side pump also
primary
switches off unless the anti-freeze alarm is triggered). This
default parameter is SI (YES) (primary enabled).
Recovery control may be enabled or disabled
If recovery is disabled the unit no longer produces cooling or
Enables
heating on the recovery side (the recovery side pump also
recovery
switches off unless the anti-freeze alarm is triggered). This
default parameter is YES (recovery enabled).

State of the circuits

Pressing the UP and DOWN keys, from the main screen it is possible to scroll
some menus that allow to control the state of the unit and some settings. The first
screen to be displayed is the cooling state of circuit 1 and then the other circuits (if
more than one).
Screen code. The letter indicates the menu, while the
