For the installer
(G30, G32) Solar pumps
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.
(G30) Circulation pump, solar collector
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 X5 pole 1
GND: brown X5 pole 2
Check the function by test running the pump in menu
“Installer/Service/
Function test”
in the control system.
(G32) Circulation pump, plate heat exchanger – solar energy
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 X5 pole 3
GND: brown X5 pole 4
Check the function by test running the pump in menu
