Commissioning 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.
Do not apply voltage to the controller before that.
Prim ary circuit
1.
Ensure for the correct integration of the fresh water station into the
potential equalisation of the system.
2.
Connect the fresh water station to the power supply
system (230 V, 50 Hz).
3.
Slowly open the piston valve on the secondary side (C) and (D).
4.
Remove the front panel of the controller
(see controller instructions, page 5).
5.
In the selection menu of the controller, select manual mode ("H1").
Switch on the PWM signal of the pump ("100 %").
6.
Allow the pump to run for a few minutes in order to vent the fresh
water station.
7.
If you can still hear air sounds after this, actuate vent valve (H)
carefully when the pump is still running and allow the air to escape.
8.
If you cannot hear any air noises anymore, turn off the pump.
For this purpose, select manual mode ("H1") in the selection menu
of the controller.
9.
Set the pump to automatic mode ("A").
10.
Open the warm domestic water tapping point (e.g., tap) with a flow rate
of minimum 10 l/min and allow the water to run for approx. 2 minutes in
order to vent the secondary circuit.
Then close all tapping points in the secondary circuit.
11.
Check the station for leaks.
12.
Set the desired warm domestic water temperature on the controller
13.
The fresh water station WHI freshaqua 44 or 55 is now ready for
operation.
14.
The station controller "learns" the system-specific control parameters
during longer tapping operations. This "learning process" is
continuously translated into practice. To achieve immediately optimum
comfort, once commissioning is complete, water should be tapped on
a few different service water fittings for about 30 s.
