(1)
SW1.1, SW1.2 – Fan speeds:
2 speeds (Low and High):
3 speeds (Low, Med., and High):
SW1.1 = OFF, SW1.2 = ON
SW1.1 = OFF, SW1.2 = OFF
(2)
SW1.4 – HP (Heat pump):
HC (not heat pump):
ON = Heat pump active in cool, OFF = Heat pump active in heat
ON = Electrical heater, OFF = Oil/Gas heater (no fan)
(3)
SW1.5 – Compressor delay:
ON = Disable, OFF = Enable
(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 (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.
