Commissioning

7.1

Filling the heating system

Monitoring the screw joints

Due to vibration and thermal expansion, all screw
joints  must  be  inspected  and  tightened  prior  to

commissioning. 

Permissible media

Heating water according to ÖNORM H 5195-1.
The  permissible  water  hardness  for  the  heating
water can be determined from the table in Section

8 "Water hardness"

.

The requirements of ÖNORM H 5195-1 apply
as  minimum  requirements  for  the  heating

water. If stricter country-specific regulations exist,
they are to be heeded.

Water/glycol  mixtures  with  a  glycol  ratio  of
minimum 20% and maximum of 30%

Glycol  has  a  higher  viscosity  than  water.
When  admixing  glycol,  the  pumping  data

must  be  corrected  according  to  the  mixing  ratio.
Proper use includes compliance with these instruc-
tions as well as the information and labelling on the
pump.

Filling and bleeding the heating system

Fill the heating system and take note of the maximum
water  pressure.  Carefully  bleed  the  heating  system
after filling.

Bleeding before commissioning

There  is  a  bleed  screw  on  the  top  of  the  module  for
bleeding the primary side.

Fig. 7-1: Bleed screw

Bleeding the pump

The  heating  system  must  be  filled  and  bled
before the pump can be bled. The pump automat-

ically bleeds itself when starting for the first time. If it
does not, carry out the following steps.
1. If the pump is not in operation, start it manually. To

do this, carry out the following intermediate steps:
a) Up to software version X.35.X

Raise the authorisation to [Service]. Switch to
the  inputs  and  outputs  menu  in  the  function
block  of  the  heating  circuit  [I/O  menu] 

.

Select the heating circuit pump and press the
[Terminal] button. In the open window, switch
on  the  output  manually  by  pressing  the  [On]
button.

b) Software version X.36.0 and later

Raise the authorisation to [Service]. Switch to
the  inputs  and  outputs  menu  in  the  function
block of the heating circuit 

. Tap on the 

symbol on the heating circuit pump. The pump
is turned on manually with the [On] button, and
turned off by pressing the [Off] button.

2. If the pump is in operation, press the control button

on the pump for 3 seconds.

Fig. 7-2: Venting

3. The  venting  function  now  starts  and  lasts  for  10

minutes.  The  upper  and  lower  LED  rows  flash
alternately every second.

To cancel, press the control button again for 3
seconds.

After venting, the LED display shows the
operating mode of the pump that was previously

set. After bleeding, the operating mode of the pump
may need to be adjusted.
