7.3 Commissioning the controller
DANGER!
Danger due to electric shock!
Check whether the probes and pumps to the
controller are connected and whether the con-
troller housing is closed. Only then should you
insert the power plug into the socket.
1.
Remove the controller's front panel (see the
controller instructions).
2.
In the selection menu of the controller, select
manual operation ("H1"). Switch the PWM
signal of the pump on ("100 %").
3.
Allow the pump to run for a few minutes in
order to bleed the fresh water station.
4.
If you are still hearing air noises after this
point, carefully actuate the bleeder (M), while
the pump is still running, and allow the air to
escape.
5.
If you no longer hear any air noises, switch
the pump off. To do this, select manual oper-
ation ("H1") in the selection menu of the con-
troller.
6.
Set the pump to automatic operation ("A").
7.
Slowly open the piston valves on the secon-
dary side ("G" and "H").
8.
Öffnen Sie eine Trinkwarmwasser-Zapfstelle
(z. B. Wasserhahn) mit einem Durchfluss von
mindestens 10 l/min und lassen Sie das
Wasser ca. 2 Minuten lang laufen, um den
Sekundärkreis zu entlüften. Schließen Sie
danach alle Zapfstellen im Sekundärkreis.
9.
Use the pre-assembled power supply cable
to connect the fresh water station to the
mains (230 V, 50 Hz).
10.
Ensure that the fresh water station is cor-
rectly included in the equipotential bonding of
the system.
11.
Set the required domestic hot water tempera-
ture on the controller (see the following
page).
12.
The fresh water station is now ready for oper-
ation.
