Installation Electrical
The following Variable Air Volume controls are available from the factory for
field installation
Remote Zone Sensor (BAYSENS016*)
This bullet type temperature sensor can be used for; outside air (ambient) sensing, return air
temperature sensing, supply air temperature sensing, remote temperature sensing (uncovered),
and for VAV zone reset. Wiring procedures vary according to the particular application and
equipment involved. Refer to the unit wiring diagrams, engineering bulletins, and/or any specific
instructions for connections. See Table 10 for the Temp vs Resistance coefficient.
Remote Panel W/O NSB (BAYSENS021*)
This electronic sensor features two system switch settings (Auto and Off), four system status LED's
with single setpoint capability. It can be used with a remote zone temperature sensor
BAYSENS077*.
The following Constant Volume or Variable Air Volume controls are available from the factory for
field installation.

Notes:
1. If Cooling is selected the supply fan will run continuously. If VAV Heating is activated the supply fan
will run continuously.
2. If Daytime Warmup is Activated, the supply fan will run
continuously.
3. Auto changeover between Cooling and Daytime
Warmup depends upon the DWU initiate setpoint.
4. The fan will be Off any time the system selection switch
is "Off".
