12. COMMISSIONING
Commissioning by trained technical personnel may only be performed after any risk has been ruled out. The
following checks should be performed in accordance with the installation and operating manual and the regu-
lations in force:
■
Correctly sealed installation of the unit and duct system.
■
Check the duct system, unit and medium lines, if present, remove any foreign bodies if necessary.
■
The intake opening and inflow into the unit must be clear.
■
Check all mechanical and electrical protection measures (e.g. earthing).
■
Voltage, frequency and type of current must correspond with the rating plate.
■
The pressure measuring tube will be laid in the duct.
■
Setting of the desired differential pressure see 13. Operation

CAUTION! Isolate electrical installation!

Adjust set-point
After removing the cover, you have free access to the pressure regulation circuit board.
Adjust set-point for the desired differential pressure at the two upper decade switches (8).
Switching the regulator on and off
Bridging terminals X5 and X6 switches the constant pressure regulator CON P1000 on, and removing the bridge swit-
ches it off again.
Turning the night mode ON and OFF
By bridging the terminals X3 and X4 the night mode is switched on, by removing the bridge, it is switched off.
Changing day-time set-point
Adjust set-point Day with the decade switches (8).
e.g. 3 2 = 32 x 10 = 320 Pa
Adjusting the night-time set-point
Adjust set-point Night with the decade switches (9).
e.g. 4 1 = 41 x 10 = 410 Pa
