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
2
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.
