Zone Sensor Module (ZSM)
(BAYSENS008B)
This electronic 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 BAYSENS017B.
Zone Sensor (BAYSENS010B)
This electronic sensor features four
system switch settings (Heat, Cool,
Auto, and Off) and two fan settings
(On and Auto) with four system
status LED's. It is a manual or auto
changeover control with dual
setpoint capability. It can be used
with a remote zone temperature
sensor BAYSENS017B.
Wall Mounted Relative
Humidity Sensor
(BAYSENS036A)
Field installed, wall mounted
humidity sensor is used to control
activation of the hot gas reheat
dehumidification option. Humidity
set points can be selected for relative
humidity levels between 40% and
60% by adjusting the DEHUMID
setting on the ReliaTel Options
Module. See Figure 29 on page
Duct Mounted Relative
Humidity Sensor
(BAYSENS037A)
Field installed, duct mounted
humidity sensor is used to control
activation of the hot gas reheat
dehumidification option. Humidity
set points can be selected for relative
humidity levels between 40% and
60% by adjusting the DEHUMID
setting on the ReliaTel Options
Module. See Figure 29 on page
Programmable Zone Sensor -
(BAYSENS019B)
This 7 day programmable sensor
features 2, 3 or 4 periods for
Occupied or Unoccupied
programming per day. If the power is
interrupted, the program is retained
in permanent memory. If power is off
for an extended period of time, only
the clock and day may have to be
reset.

The Zone Sensor allows selection of
2, 3 or 4 system modes (Heat, Cool,
Auto, and Off), two fan modes (On
and Auto). It has dual temperature
selection with programmable start
time capability.
The occupied cooling set point
ranges between 45 and 98 degrees
Fahrenheit. The heating set point
ranges between 43 and 96 degrees
Fahrenheit.
A liquid crystal display (LCD) displays
zone temperature, temperature set
points, day of the week, time, and
operational mode symbols.
The Option Menu is used to enable or
disable applicable functions, i.e.;
Morning Warm-up, Economizer
minimum position override during
unoccupied status, Fahrenheit or
Centigrade, Supply air tempering,
Remote zone temperature sensor, 12/
24 hour time display, Smart fan, and
Computed recovery.
During an occupied period, an
auxiliary relay rated for 1.25 amps @
30 volts AC with one set of single
pole double throw contacts is
activated.
Status Inputs (4 Wires
Optional)
The ZSM can be wired to receive four
28.
(4) operating status signals from the
RTRM (HEAT, COOL, SYSTEM "ON" ,
SER-VICE).
Four (4) wires from the RTRM should
be connected to the appropriate
terminals (7, 8, 9 & 10) on the ZSM.
Remote Zone Sensor
(BAYSENS013B)
This electronic sensor features
remote zone sensing and timed
override with override cancellation. It
is used with a Trane Integrated
28.
ComfortTM building management
system.
Remote Zone Sensor
(BAYSENS014B)
This electronic sensor features single
setpoint capability and timed
override with override cancellation. It
is used with a Trane Integrated
ComfortTM building management
system.
General Information
Remote Zone Sensor
(BAYSENS016A)
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
(BAYSENS017B)
This electronic sensor can be used
with BAYSENS006B, 008B, 010B,
019B Remote Panels. When this
sensor is wired to a BAYSENS019B
Remote Panel, wiring must be 18
AWG Shielded Twisted Pair (Belden
8760 or equivalent). Refer to The
specific Remote Panel for wiring
details.
Electro Mechanical Control
The unit must have a Thermostat to
operate.

High Temperature Sensor
(BAYFRST001A)
This sensor connects to the RTRM
Emergency Stop Input on the LTB
and provides high limit "shutdown"
of the unit. The sensor is used to
detect high temperatures due to fire
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
(X1310004001) is set to open at 135 F .
The supply air duct sensor
(X1310004002) is set to open at 240 F .
The control can be reset after the
temperature has been lowered
approximately 25 F below the cutout
setpoint.
