SW3.1, SW3.2 = Fan speeds: 2 Speeds (Low and High):
SW3.1 OFF, SW3.2 ON
3 Speeds (Low, Med. and High): SW3.1 OFF, SW3.2 OFF
(2)
SW3.4 = HP (Heat pump):
ON – Heat pump active in cool, OFF – Heat pump active in heat
HC (Not Heat pump): ON – Electrical heater,
OFF – Oil/Gas heater (no fan)
(3)
SW3.5 = Compressor delay:
ON – Disable compressor delay, OFF – Enable compressor delay
(5)
SW1.6 = Terminal 12 operation: ON – Economizer
OFF – Fan Med. (3 Speeds) / Terminal not in use (2 Speeds)
Important: Economizer will not work in 3 fan speeds configuration
