1 speed (Low):
2 speeds(Low and High):
3 speeds(Low, Medium, and High):
ON = Enable, OFF = Disable
ON = Enable chilled beam (fan will not run with cooling)
ON – Use dehumidifier, OFF – Use reheat for dehumidification
ON = Economizer
OFF = Fan Medium (3 speeds) / Terminal not in use (1/2 speeds/VFS)
Important: Economizer will not work in 3 fan speeds configuration.
