Dip Switch Settings and Air Temperature Sensor Position
As supplied the air curtain is set-up to be operated under Weather Compensation
Control (HEATING ECO) or Discharge Air Temperature Control (HEATING) and the air
temperature sensor (marked red) is located in a temperature pocket in the air discharge
plenum of the unit. Check that the dip switches on the Interface PCB are set as follows:

If the air curtain is going to be operated under Inlet Air Temperature Control the air
temperature sensor (marked red) needs to be removed from its temperature pocket in
the air discharge plenum of the unit and fitted in the inlet air to the fan on the bracket
provided, see pictures showing this.
If the air curtain is going to be operated under Room Air Temperature Control it does
not matter where the air temperature sensor (marked red) is located as air temperature
sensing is now done at the PAR-30MAA Remote Controller. The PAR-30MAA Remote
Controller will need to be set up via its Installer Menu so that temperature sensing is
done at the controller. See instructions that come with the controller. Check that the dip
switches on the Interface PCB are set as follows:
For Inlet Air Temperature Control or Room Air Temperature Control

Check that the wiring between the air curtain and the Mr Slim outdoor unit is in
accordance with Wiring Diagrams 1 & 2 on Pages 16 and 17. If the Interface PCB is still
withdrawn, carefully slide it back into place and re-plug the Filter Indication connection
into CN105 if removed earlier. Ensure cables are not trapped inside and refit the
retaining screw.
