mode (on the screen –
MOn
or
MOf
) is control with setting time period
during which relay status ‘
Heating On
’ or ‘

The mode with relay setting either for state ‘
Heating On
’ or ‘

Special abbreviation used for state ‘
Heating On

Heating Of
’ .
It’s a logical state not corresponding to relay status with closed or opened contacts . When con-
trol algorithm activates heating, it appears on the screen as
On
. For this case relay contacts can
be either with an opened circuit state or with a closed-circuit condition which are determined
by the setting
Relay
status RO/RC
– Relay Opened (
RO
) or Relay Closed (

Relay status
RO/RC
for state
Heating On
– Relay Opened (
RO
) or Relay Closed (
RC
) .
For the heating mode on, the corresponding state of the relay contacts can be selected –
