SW3.1, SW3.2 = Fan speeds:
1 Speed (Low):
SW3.1 ON, SW3.2 OFF
2 Speeds (Low and High):
SW3.1 OFF, SW3.2 ON
3 Speeds (Low, Medium and High): SW3.1 OFF, SW3.2 OFF
(2)
SW3.4 = 2
nd
heating stage:
ON – Enable,
OFF – Disable
(3)
SW3.5 = Chilled beam option
ON – Enable chilled beam (fan will not run with cooling)
(5)
SW1.6 = Terminal 12 operation: 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
