CTC EcoLogic Pro/Family
For the installer
10.2.9.2 Charge pump – recharging bore hole (G31)*
230 V 1N~
The charge pump is connected at the following terminal blocks:
(G31) Charge pump, expansion card (X6):
Phase: pole 8 also controls Diverting valve –
solar (Y31)
Zero: pole 11
Earth: pole 10
Pole 8 is connected to an external connection box which distributes voltage to
the solar diverting valve (Y31) and the Recharge Bore Hole charge pump (G31).
Refer to the wiring diagram.
Check the function by test running the pump in menu “Installer/Service/Function
test”.
10.2.10 Pool pumps (G50) and (G51)
230 V 1N~
Both pumps (G50) & (G51) are connected to the following terminal blocks:
Pumps pool (G50) and (G51), expansion card X7:
Phase: pole 33
Zero: pole 35
Earth: pole 34
Pole 33 is connected to an external connection box which distributes voltage to
the charge pump (G50) and circulation pump (G51).
Check the function by test running the pump in menu “Installer/Service/Function
test” in the control system.
10.3 Protection - low voltage (sensor)
The sensors that form part of each system solution (schematic diagrams 1
to 6) should be itted to the PCB/terminal block as follows: All sensors are
temperature sensors.
