SW1.1, SW1.2 – Fan speeds:
1 speed (Low):
2 speeds(Low and High):
3 speeds(Low, Medium, and High):
SW1.1 = ON, SW1.2 = OFF
SW1.1 = OFF, SW1.2 = ON
SW1.1 = OFF, SW1.2 = OFF
(2)
SW1.4 – 2nd heating stage:
ON = Enable, OFF = Disable
(3)
SW1.5 – Chilled beam option:
ON = Enable chilled beam (fan will not run with 1st stage cooling)
(4)
SW2.3 – Dehumidification:
ON = Use dehumidifier
OFF = Use reheat for dehumidification
(5)
SW2.6 – 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 in Wiring terminals and DIP switches (page 23) for DIP switch locations.
Fan on/off: 110-230 Vac, 2.5A max.
Fan VFS, PID valves: 0-10 Vdc, 0.5 mA Not isolated
Control – Heat elements, Cool/Heat valves, Economizer: 110-230 Vac, 0.3A max.
