3. Controller parameter and indication channels
3.1 Channel-overview
Legend:
x*
Corresponding channel is available if the appropriate option
is activated.

Corresponding channel is only available if the option energy
production measurement is
activated
(OHQM).
MEDT
The channel antifreeze content (MED%) is only shown if a
medium other than
water or propylene glycol
is used.
The adjustment is only appropriate when using other types
of antifreeze.

Corresponding channel is only available if the option energy
production measurement is
deactivated (OHQM).
Please note:
S3 and S4 are only indicated if sensors are connected.
