General Information
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 page
24.
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 opera-
tional mode symbols.
The Option Menu is used to enable or disable applicable
functions, i.e.; Morning Warm-up, Economizer minimum posi-
tion override during unoccupied status, Fahrenheit or Centi-
grade, Supply air tempering, Remote zone temperature sen-
sor, 12/24 hour time display, Smart fan, and Computed recov-
ery.
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 (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 Comfort
TM
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 Comfort
TM
building management system.
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 (un-
covered. 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 equiva-
lent). Refer to The specific Remote Panel for wiring details.
Electro Mechanical Control
The unit must have a Thermostat to operate.
BAYSTAT036A
Single Stage - 1 Heat/1 Cool
BAYSTAT037A
Multi Stage - 2 Heat/2 Cool - Can be Used for Economizer

Remote sensor for BAYSTAT036A and BAYSTAT037A
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 ap-
proximately 25 F below the cutout setpoint.
Evaporator Frost Control
(ReliaTel™ Option)
This input incorporates the Frostat™ control (FOS)
mounted in the indoor coil circuit and can be activated by
closing a field supplied contact installed in parallel with
the FOS.
If this circuit is open before the compressor is started, the
compressor will not be allowed to operate. Anytime this
circuit is opened for 1 continuous second during compres-
sor operation, the compressor for that circuit is immedi-
ately turned “Off”. The compressor will not be allowed to
restart for a minimum of 3 minutes should the FOS close.
(Electro Mechanical Option)
This input incorporates the Frostat™ control (FOS)
mounted in the indoor coil circuit and can be activated by
opening a field supplied contact installed in series with the
FOS.
If this circuit is open before the compressor is started, the
compressor will not be allowed to operate. Anytime this
circuit is opened during compressor operation, the com-
pressor for that circuit is immediately turned “Off”. The
compressor will restart when the FOS closes.
