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 FriwaMini.
4. If you continue to hear air noises after this,
connect a hose to the ball valve for filling/
drainage (B). Carefully actuate the ball valve
for filling/drainage (B) while the pump is still
running and allow the air to bleed out.
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 (A and L).
8. Open a domestic hot water dispensing con-
nection (e.g. water valve) with a flow of at
least 10 l per minute and allow the water to
run for around 2 minutes, in order to bleed
the secondary circuit. Then close all dis-
pensing connections in the secondary circuit.
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.
