FIGHTER 1120
RG 10, sensor for changing the room temp.
An external sensor can be connected to FIGHTER 1120
to change the flow temperature and with that set the
room temperature, for example, a room sensor (RG 10,
accessory). The sensor is connected on terminals X1:3,
X1:4 and X1:14 on the load monitor card (2).
The difference between the room temperature and the
set room temperature affects the flow temperature.
The required room temperature is set using the knob
on RG 10 and is shown in menu 6.0.
Contact for changing the room temperature
An external contact function can be connected to
FIGHTER 1120 to change the flow temperature and in
doing so change the room temperature, for example, a
room thermostat (accessory) or a timer. The contactor
should be potential free and momentary and is con-
nected to terminals X1:3 and X1:4 on the load monitor
card (2).
When the contact is made, the heating curve offset is
changed by the number of steps shown here. The
value is adjustable between -10 and +10. The value for
the change is set on menu 2.5, “Compensation exter-
nal”.
Contact for activation of “Extra hot water”
An external contact function can be connected to FIGHT-
ER 1120 for activation of the “Temporary extra hot water”
function. The contactor should be potential free and
momentary and is connected to terminals X4:3 and X4:4
on the load monitor card (2).
When the contact makes for at least one second, the
“Temporary Extra hot water” function is activated. An
automatic return to the previously set function occurs
after 24 hours.
NV 10, Pressure/level monitor brine
When a level monitor NV 10 (accessory) is required for
the brine installation, this can be connected to termi-
nals X1:16 and X1:17. In order for this to be active you
must change menu 9.2.11, brine pressostat, to “On”.
The contact shall be made during normal operating
conditions.
