Main Board Outputs
Overview of outputs / general notices:
The status of these outputs Reserve 1
– Reserve
4 can be queried via the menu level 1 on the dis-
play. See Chapter .
Fig. 45: main board outputs
8.4.1
"Sensor FKY" Output (Inactive)
Inactive / cannot be used
Fig. 46: sensor FKY output
8.4.2
"Pump" Output (Inactive)
Inactive / cannot be used
Fig. 47: pump output
8.4.3
"Reserve 1" Output (Operating
message)
3-pole relay output (normally open) with mains
voltage / 230 V AC (unregulated): for connection
of external devices which require a signal with
mains voltage during operation of the furnace (e.g.
wodtke flue gas damper AK1).
Fig. 48: Reserve 1 output
Output R1 ON = 230 V / mains voltage =
furnace in operation Note: G OFF applies
as operation.
Output R1 OFF = 0 V = furnace off or fur-
nace not ready (e.g. voltage failure, fur-
nace shut down via
button or furnace
shut down via external / internal control-
ler).
8.4.4
"Reserve 2" Output (Collective
fault message)
3-pole relay output (normally open) with mains
voltage / 230 V AC (unregulated): for connection
of external devices which require a signal with
mains voltage in case of furnace fault.
Fig. 49: Reserve 2 output
Output R2 ON = 230 V / mains voltage =
fault-free operation
Output R2 OFF = 0 V = fault, voltage fail-
ure or unit shut down via
button.
8.4.5
"Reserve 3" Output (Fault Mes-
sage, Pellet Chute Temperature TP)
3-pole triac output (normally open) with mains volt-
age / 230 V AC (unregulated): for connection of
external devices which require a signal with mains
voltage in case of temperature too high in the pel-
let chute (e.g. visual or acoustic warning signal,
bell, etc.).
Fig. 50: Reserve 3 output
Output R3 ON = 230 V / mains voltage =
TP temperature too high
Output R3 OFF = 0 V = TP temperature
OK
