The following tables detail the the configuration DIP switches for the system control modules.
Factory default settings are OFF.
To facilitate the commissioning process, each control modules DIP switches should be set to
the positions indicated by the shading.
NOTE: The outdoor unit DIP switches 1 and 4 must be returned to the OFF position at the end
of the commissioning process for normal operation.

Before connecting power
Ensure all electrical and control connections have been made as per the relevant connection
diagram in Appendix A. If the wall controller sensor is to be the system sensor, ensure DIP
switch 1 on the wall controller is on.
Initial Power On
When power is applied to the system, the start-up routine will check communication to each
control module. Check the main modules for red fault LEDs.
Maximum Fan Speed Reduction
Maximum Fan Speed should only be reduced if register noise at all outlets is above an
acceptable level. For instances where register noise is not acceptable at one or two registers,
use the air balance to rectify.
To reduce the maximum fan speed, DIP switches 6, 7 and 8 on the Indoor Unit Module can be
switched to the ON position.
