9. Commissioning
Connect the power cable and accessories in accordance with the wiring diagram
provided.
A high leakage current can be expected due to the EC motors.
Ensure that a secure earth connection is in place before connecting the
power supply and commissioning.
If control voltage is present or a set speed is saved, the EC fans will restart
automatically, e.g. after a power failure.
- Switch the isolator ON
- Wait until the BMK programming unit initialises and changes to the display
mode.
- Select the required operating mode at the BMK; the system will start with
the preset parameters.
- To modify functions and parameters, see the installation and operating
instructions provided.
Where the system is not commissioned by Wolf, check all inputs and outputs
for correct wiring and function:
- Frost protection function
- Fan rotational direction
- Outdoor air/extract air damper rotational direction
- Plausible sensor values (room sensor, supply air sensor, extract air
sensor, outdoor air sensor, ice sensor)
- Measure motor currents
- Motor protection (thermal contacts / PTC thermistor)
- Airflow monitoring
- Filter monitoring
- Bypass damper function (rotational direction)
- Heating actuator
- Heating circuit pump
- As well as all other system-specific functions
The Wolf warranty will be void if the function test is not carried out correctly.
