Zone temperature sensor w/timed override and local setpoint adjustment, accessory model number digit 6 = C

Integrated Comfort™ Systems Sensors for CV andVAV Applications

These zone sensor options are for use with cooling/heating Integrated Comfort System (ICS) systems.

BAYSENS074 Description

This electronic analog sensor features single setpoint capability and timed override with override cancellation.

BAYSENS074 features and system control functions include:

•Remote temperature sensing in the zone

•A timed override button to move an ICS or a building management system from its “unoccupied” to “occupied” mode.

•Thumbwheel for local setpoint adjustment

•A cancel button to cancel the “unoccupied override” command.

(Possible Schematic Designation: 5U23)

BAYSENS073 Description

This electronic analog sensor features single setpoint capability and timed override with override cancellation. It is used with aTrane Integrated Comfort system.

BAYSENS073 features and system control functions include:

•Remote temperature sensing in the zone

•A timed override button to move an ICS or a building management system from its “unoccupied” to “occupied” mode.

•Cancel button to cancel the “unoccupied override” mode.

Single setpoint sensor with system function lights, accessory model number digit 6 = H

BAYSENS021 Description

This zone sensor module is for use withVAV units without night setback. It allows the user to control system operation and monitor unit operating status from a remote location.The sensor has a system switch, a S/A temperature setpoint indicator, a local sensor, and four LED’s.

BAYSENS021 features and system control functions include:

•Temperature sensing in the zone

•System control switch with mode setting for "AUTO" and "OFF"

•Supply air single temperature setpoint

•Function status indicator lights:

“SYS ON” glows continuously during normal operation, or blinks if system is in test mode.

“COOL” glows continuously during cooling cycles, or blinks to indicate a cooling system failure.

“HEAT” glows continuously during heating cycles, or blinks to indicate a heating system failure.

“SERVICE” blinks or glows to indicate a problem. These signals vary depending on the particular equipment being used.
