Commissioning of the controller
WARNING
Risk to life and limb due to electric shock!
Check whether the sensors and pumps have been connected to the
controller and the controller housing is closed.
Only under these circumstances, the mains plug of the controller can be
plugged into a socket.
1.
Connect the domestic hot water module to the
mains (230 V, 50 Hz) by using the premounted
connection cable.
2.
Carry out the commissioning of the controller
(see controller instructions, chapter
Commissioning
). After that, start the pump in the
automatic/manual mode (PWM signal = 100 %,
see controller instructions chapter
Automatic/manual mode
).
3.
Let the pump run for several minutes to vent the
domestic hot water module.
4.
If the air noises do not stop, carefully manipulate
the vent valve (L) while the pump is still running
and let the air escape.
5.
If the air noises have stopped, the pump can be
switched off.
6.
To do so, in the automatic/manual mode, set the
pump to "Automatic".
7.
Slowly open the piston valves (F) and (G) on the
secondary side.
