SW1.1 OFF, SW1.2 ON
3 Speeds (Low, Med. and High): SW1.1 OFF, SW1.2 OFF
(2)
SW1.4 = 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)
SW1.5 = Compressor delay: ON – Disable compressor delay, OFF – Enable compressor delay
(5)
SW2.6 = Terminal 12:
ON – Economizer
OFF – Fan Med. (3 Speeds) / Terminal not in use (1/2 Speeds/VFS)
Important: Economizer will not work in 3 fan speeds configuration
