SW3.1, SW3.2 – Fan speeds:
1 speed (Low):
2 speeds(Low and High):
3 speeds(Low, Medium, and High):
SW3.1 = ON, SW3.2 = OFF
SW3.1 = OFF, SW3.2 = ON
SW3.1 = OFF, SW3.2 = OFF
(2)
SW3.4 – 2nd heating stage:
ON = Enable, OFF = Disable
(3)
SW3.5 – Chilled beam option:
ON = Enable chilled beam (fan will not run with cooling)
(4)
SW1.3 = Dehumidification:
ON – Use dehumidifier, OFF – Use reheat for dehumidification
(5)
SW1.6–Terminal 12 operation:
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.
See drawing for DIP switch and jumper locations (page 24).
