2-point output configuration
The two-point outputs (terminals 7, 6, 4, 3) can be configured according to the following table (setting values SERV 04...07).
–1
=
No function (output is not used)
+00
=
Time channel to exterior. ON (= 1) and OFF (= 0) commands can be entered in the time
programs. Using these commands, any load can be switched on and off in a time-
dependent pattern, independent from the heating system (time-switch function).
+01
=
Actuation of the circulation pump of heating circuit 1 (UP1). UP1 is always assigned to
heating circuit 1.
+02
=
Actuation of the circulation pump of heating circuit 2 (UP2). UP2 is always assigned to
heating circuit 2.
+03
=
LP 1 charges either the domestic-hot-water tank or a heat exchanger for domestic-
hot-water charging.
+04
=
Actuation of the domestic-hot-water circulation pump. ON (= 1) or OFF (= 0) commands
can be entered in the time programs. With this function, the domestic-hot-water circulation
pump can be switched on and off in a time-dependent pattern (with anti-jamming function).
+05
=
LP 2 is connected in series to LP 1 and charges the domestic-hot-water tank.
+06
=
Internal circulation pump (secondary; automatically regulated by controller).
+07
=
Contact is actuated in
and
operation of heating circuit 1, provided that UP 1 is
switched on. This signal can be connected to a pump-speed governor in order to reduce
pump speed during
and
operation (with activated frost protection).
+08
=
Contact is actuated in
and
operation of heating circuit 2, provided that UP 2 is
switched on. This signal can be connected to a pump-speed governor in order to reduce
pump speed during and
operation (with activated frost protection).
+09
=
Contact is actuated during the optimised warm-up phase of heating circuit 1.
+10
=
Contact is actuated during heat demand (for main primary pump or boiler pump)
