If the boiler is fitted with the control PCB (SCU-S02), then this is
automatically recognised by the automatic control unit of the boiler.
CAUTION
On removing this PCB, the boiler will show fault code
e[38
. To prevent this fault, an auto-detect must be
carried out after removing this PCB.
¼ See chapter: "Carrying out an auto-detect", page
75.
The status indicator D3 at the top right of the control PCB indicates
the status:
4
Continuous signal: PCB working normally
4
Flashing signal: No connection
4
No signal: No voltage or faulty PCB (Check the wiring)
n
Control of external central heating pump (Pump)
An external central heating pump can be connected to the
Pump
terminals of the connector. The maximum input power is 400 VA.
n
Control of external three-way valve (3wV)
The external three-way valve (230 VAC) can be used when
connecting an indirectly heated calorifier. The neutral position of the
three-way valve can be set using parameter
p34
.
The three-way valve is connected as follows:
4
N = neutral
4
C = central heating
4
D = tank
n
Control of external sanitary hot water pump (3wV)
It is also possible to connect an external DHW pump to the terminals
3wV
. Connect the pump as follows:
4
N = N pump
4
D = L pump
4
Q = PE pump
CAUTION
If the neutral position of the 3-way valve is adjusted with
parameter
p34
, the pump should be connected as
follows:
4
N = N pump
4
C = L pump
4
Q = PE pump
