Remote Zone Sensor (BAYSENS074*)
This electronic 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 (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 (BAYSENS077*)
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.
Wireless Zone Sensor (BAYSENS050)
This electronic sensor features five system settings (Auto,
Off, Cool, Heat, and Emergency Heat) and with On and
Auto fan settings. It is a manual or auto changeover control
with dual setpoint capability. Other features include a
timed override function, lockable system settings, and
Fahrenheit or Celsius temperature display. Included with
the wireless zone sensor will be a receiver that is to be
mounted inside the unit, a mounting bracket, and a wire
harness.
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 135ºF. The supply air duct
sensor (X1310004002) is set to open at 240ºF. The control
can be reset after the temperature has been lowered
approximately 25ºF 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
compressor operation, the compressor for that circuit is
immediately turned “Off”. The compressor will not be
allowed to restart for a minimum of 3 minutes should the
FOS close.
Discharge Line Temp Switch (DLTS)
The DLTS is looped in series with HPC and LPC. It prevents
compressor from overheating (over 300ºF dome temp) in
case of ID fan failure (cooling) or OD fan failure (heating).
Phase Monitor
This sensor monitors voltage between the 3 conductors of
the 3 phase power supply. Two LED lights are provided.
The green light indicates that a balanced 3 phase supply
circuit is properly connected. The red light indicates that
unit operation has been prevented. There are two
conditions that will prevent unit operation.The power
supply circuit is not balanced with the proper phase
sequence of L1, L2, L3 for the 3 conductors of a 3 phase
circuit. The line to line voltage is not between 180 volts and
633 volts
