Manual/Automatic Changeover
(BAYSENS108*)
This sensor features four system switch settings (Heat,
Cool, Auto, and Off) and two fan settings (On and Auto). It
is a manual or auto changeover control with dual setpoint
capability. It can be used with a remote zone temperature
sensor BAYSENS077*.
Wall Mounted Relative Humidity Sensor
(BAYSENS036*)
Field installed, wall mounted humidity sensor that
measures temperature and relative humidity. Relative
humidity input is used to control activation of
dehumidification
Duct Mounted Relative Humidity Sensor
(BAYSENS037*)
Field installed, duct mounted humidity sensor that
measures temperature and relative humidity. Relative
humidity input is used to control activation of
dehumidification.
Integrated Comfort System
(BAYSENS073*)
This sensor features remote zone sensing and timed
override with override cancellation. It is used with a Trane
Integrated Comfort™ building management system.
Integrated Comfort System
(BAYSENS074*)
This sensor features single setpoint capability and timed
override with override cancellation. It is used with a Trane
Integrated Comfort™ building management system.
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). Wiring procedures vary according to
the particular application and equipment involved. Refer to
the unit’s wiring diagrams for proper connections.
Remote Zone Sensor (BAYSENS077*)
This sensor can be used with BAYSENS106*, 108*, 110*,
800* Remote Panels. When this sensor is wired to a
BAYSENS800* Remote Panel, wiring must be 18 AWG
Shielded Twisted Pair (Belden 8760 or equivalent). Refer to
the specific Remote Panel for wiring details.
Thermostat
The unit must have a thermostat to operate.
• BAYSTAT151
One Heat/One Cool Auto changeover digital display
thermostat.
• BAYSTAT155
Three Heat/Two Cool Auto changeover display
thermostat.
• BAYSENS150
Three Heat/Two Cool Auto changeover digital
display thermostat. Seven day programmable
thermostat with night setback.
High Temperature Sensor (FIAHTST001*)
This sensor connects to the Symbio™ 700 Emergency
Stop Input and provides high limit “shutdown” of the unit.
The sensor is used to detect high temperatures due to a
high thermal event in the air conditioning or ventilation
ducts. The sensor is designed to mount directly to the
sheet metal duct. Each kit contains two sensors. The return
air duct sensor (X13100040010) is set to open at 135ºF.
The supply air duct sensor (X13100040020) is set to open
at 240ºF. The control can be reset after the temperature
has been lowered approximately 25ºF below the cutout
setpoint.
Digital Display Zone Sensor
(BAYSENS135*)
LCD display provides heat, cool, auto, on, and off status.
Display includes two temperature setpoints, and a lockable
setting with °F or °C indicators.
Touch Screen Programmable Zone
Sensor (BAYSENS800)
This sensor uses a BACnet® MS/TP link to communicate
zone temperature and setpoints. Sensor includes Auto,
Heat, Cool, or Off system switch, as well as Fan Auto or On
switch. This is a seven day programmable thermostat with
night setback.
Notes:
• Not compatible with VAV units. Requires
BACnet® communications.
• For additional sensors, refer to the product
catalog.
Note: BASYSENS800* with BACnet® enabled on the
Symbio™ controller will report fault detection and
diagnostics at the zone sensor. This functionality is
only applicable if the customer does not have a
building management system, and the unit is
running standalone with the BAYSENS800.
Evaporator Frost Control
Frostat is standard on all Voyager 3 27.5 to 50 ton units.
Discharge Line Temp Switch
(DLTS)
The DLTS is looped in series with HPC and LPC. It
prevents compressor from overheating (over 300°F dome
