For the installer
10.2.7 Solar pumps (G30, G32)*
The solar PWM pumps (G30 and G32) of model WILO Stratos PARA differ
from the other PWM pumps. If the PWM control signal is interrupted, the solar
pumps stop, whereas the other PWM pumps work at 100% power if the signal is
interrupted.
10.2.7.1 Circulation pump solar panels (G30)
230 V 1N~
The circulation pump is connected to the following terminal blocks:
(G30) Circulation pump, expansion card X5:
Note the cable colours!
PWM+: white pole 1
GND: brown pole 2
Check the function by test running the pump in menu
“Installer/Service/Function
test” in the control system.
10.2.7.2 Pump heat exchanger solar panels (G32)
230 V 1N~
The heat exchanger pump is connected to the following terminal blocks:
(G32) Pump, expansion card X5:
Note the cable colours!
PWM+: white pole 3
GND: brown pole 4
Check the function by test running the pump in menu
“Installer/Service/Function
test” in the control system.
10.2.8 Diverting valve solar DHW (Y30)*
230 V 1N~
The diverting valve is connected to the following terminal blocks:
(Y30) Diverting valve, expansion card X6:
Control voltage: pole 4
Phase: pole 5
Zero: pole 7
Earth: pole 6
10.2.9 Solar recharging borehole (Y31/G31)*
10.2.9.1 Diverting valve Solar (Y31)
230 V 1N~
NOTE:
It is important to connect the phase voltage to L (pole 9); refer to the
wiring diagram.
The diverting valve is connected to the following terminal blocks:
(Y31) Diverting valve, expansion card X6:
Relay output 8 A: Open to
bore hole pole 8 also controls Charge pump –
recharging bore hole (G31)
Phase: Open Tank pole 9
Zero: pole 11
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” in the control system.
