Ground water pump connection
There is a potential free relay for the ground water
pump function (CP-G), which can be used as control
voltage or power supply (Max 6 A, 250 V).
If the relay is used as control voltage, the supply can
be bridged internally from X13:4 to X6B:24, use X13:9
as N and receive the signal on X6B:25, but max cur-
rent must be 0.4 A and the control voltage is 230 V.
The external supply to the control signal/power sup-
ply for the ground water pump (CP-G) is connected to
terminal block X6B:24 (max fusing 6 A and 250 V) and
the control signal/power supply is on X6B:25.
A ground water pump (CP-G) can be controlled by
FIGHTER 1330.
The pump starts 20 seconds before the first compres-
sor starts and stops 20 seconds after the last com-
pressor stops.
