Groundwater pump
A ground water pump (CP-G) can be controlled by F1330.
The pump starts 20 seconds before the first compres-
sor starts and stops 20 seconds after the last compressor
stops.
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 X13:2 to X6B:24, use X13:3 as N
and receive the signal on X6B:25, but max current must be
0.4 A and the control voltage is 230 V.
The external supply to the control signal/power supply 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.
The outline diagram with docking instructions is
available at www.nibe.eu
