2. Plug the RJ-45 connector of the network cable
into the socket of the control panel (1).

Flushing, filling and venting
12.1 Heating water quality
NOTE
●
For detailed information refer, among
other things, to the VDI Guidelines
2035 "Vermeidung von Schäden in
Warmwasserheizanlagen" (preventing
damage in hot water heating systems).
●
Required pH value: 8.2 – 10
●
for aluminium materials: pH value: 8.2 – 8.5
►
Fill the system only with demineralised heating
water (VE water) or VDI 2035 water (low-salt
operation of the system).
Advantages of low-salt operation:
●
Low corrosion-promoting properties
●
No formation of mineral scale
●
Ideal for closed heating circuits
●
ideal pH value due to self-alkalinisation after filling
the system
●
If necessary, simple alkalinisation to pH value 8.2
by adding chemicals
12.2
Flush and fill the heating and
domestic hot water charging
circuit
Outlet pipe of the safety valve is connected.
►
Ensure that the set pressure of the safety valve is
not exceeded.
NOTE
The venting program on the controller can
also be used to support the flushing and
venting process. It is possible to control
individual circulation pumps and even the
switching valve through the venting program.
As a result it is not necessary to remove the
valve motor.
1.
Pull the U-clip (2) off the floor of the valve
motor (1).
2.
Pull the valve motor carefully off the 3-way
switching valve (3).
