Commissioning
The ventilation system must be completed with all electrical, hydraulic and air duct connections
in place before commissioning the unit. Commissioning or system settings can only be
performed once all work on the plant is complete.
The factory settings on the control unit may only be changed by the specialised installer. An incorrect
setting can result in the unit malfunctioning.
9.1
Basic procedure for commissioning by a specialist:
9.1.1
Checking prior
to commissioning
9.1.2
Setting the
system parameters
Check the system components and correct the setting if
applicable.
Set the system parameters, for example adjust the air volume
flow/fan speed.
Set the system time.
Program the time of day program in accordance with
requirements.
9.1.3
Cable feed-throughs
To connect the mains cable, optional system components or
external sensors, feed the cable through the PG feed-throughs
at the back of the controller housing into the ventilation unit.
9.1.4
Counter-current
plate heat exchanger
If there is a servo motor for the bypass flap, check to see
whether it turns in the right direction.
9.1.5
Condensate tray
Are all air ducts and subassemblies fully installed?
Are all system components fitted and electrically
connected?
Is the electric wiring complete and the control unit
fitted?
Is the condensate connection in place and functional?
Are the air vents, inlet and outlet valves (grating)
properly installed and open?
Are the air filters in the ventilation unit correctly installed
and clean?
Are the air filters in the geothermal heat
exchanger correctly installed and clean?
Are any installed fire shutters in open position?
The siphon provided with delivery must be fitted
properly. An adequate gradient (at least 5%) is
required to reliably drain the water.
During commissioning, check proper drainage of the
water and tightness of all connections.
