* Fan speed PWM limits can be set from the ActronAir units service menu. Consult the Air Conditioner units installation
guide for more information. If system has been configured as a single speed indoor fan Register 4 - Supply fan mode can
only be set to MEDIUM speed. “4=Auto” is only available on Advance Units and after a self-learn is successful from the wall
controller.
05.02. Advanced BMS Control
If the Air Conditioning unit is setup for Advanced BMS Demand Mode, then Modbus Register 505 should read a 2. If Register
505 reads any other value, then the unit has not been correctly setup to run in Advanced BMS Control. See Section 05.02 for
instructions on configuring your unit for Advanced BMS Control.
