4. Guide other end of pressure tubing
through cable feedthrough into ventilation
unit.
NOTICE
Tube connections on the ZP 2 circuit board
may be damaged if the tube is mounted
incorrectly.
Only connect pressure tubing supplied to the
(+) High or (-) Low tube couplings fitted in the
factory.
5. Insert pressure tubing into tube coupling
according to function:
(+) High: Connection variant A: supply air
fan operating with pressure consistency.
(-) Low:Connection variant B: exhaust air
fan operating with pressure consistency.
6. Slide the electronic slide-in module into the
electronic compartment and screw down if
necessary (depending on unit type).
7. Fit front cover(s)  Installation instructions
for ventilation unit.
8. Affix the retrofit sticker provided on the
ventilation unit such that it is clearly visible.
Enter installed function and date on ZP 2.
9. Switch the mains fuse on.
10. Switch on ventilation unit with main switch
(if present).
11. Release the function with the commission-
ing software or comfort control unit (install-
er level) using the following parameters.
Go to Settings/Pressure consistency and
set the Pressure consistency parameter
to yes.
Enter the desired pressure or initialize the
target pressure by specifying a volumetric
flow.
Initialization starts automatically. During
initialization, all 3 LEDs on RLS 1 WR
flash, an info message appears on the
touch control unit. Initialization may take
up to 10 minutes.
12. Test settings and functions.
For more information  Commis-
i
sioning and maintenance instruc-
tions.
After initialization, it may take up
i
to 30 minutes to achieve the target
pressure.
4.4 Filter monitoring connection
Connection variant C
1. Split the pressure tube supplied in the
middle.
2. Prepare pressure tubing for routing in the
ventilation unit by taking out any connect-
ing cable present (PTC heat register 
diagrams below).
3. Use a cutter blade to carefully cut out the
EPP bars [S] in the ventilation unit, drill
through EPP wall if necessary.
