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.
1.
Slowly open the piston valve on the secondary side (A and L).
2.
Ensure for the correct integration of the fresh water station in the potential
equalisation of the system.
3.
Connect the fresh water station to the power supply system (230 V, 50 Hz).
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 noises after that, attach a hose to fill and drain valve (B).
Actuate fill and drain valve (B) 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
(see page 25).
13.
The fresh water station is 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.
