Note:

• Heating or fan contactors are in the VAV box. The VAV controller binary outputs switch the

common. OUT1, OUT2, and OUT3 are 24 V HOT continuously.

• You can average up to five NS sensors. Connect the NS sensors in a daisy-chain

configuration using the addresses in the

Configuring the NS sensors

section. The fifth

sensor must have the fixed address 199.

• If you install CO

Net sensors, in addition to the 24 VAC power for the controller, you must

also supply 24 VAC power to the

HOT

and

COM

terminals.
