Sensors - Trane Voyager TS 150-300 Series Installation, Operation And Maintenance Manual

Power Exhaust Control (Optional)
The power exhaust fan is started whenever the position of
the economizer dampers meets or exceed the power
exhaust setpoint when the indoor fan is on.
The setpoint panel is located in the return air section and
is factory set at 25 percent.
Lead/Lag Control (Dual Circuit Only)
Lead/Lag is a selectable input located on the RTRM. The
RTRM is configured from the factory with the Lead/Lag
control disabled. To activate the Lead/Lag function, simply
cut the wire connected to J3-8 at the RTRM. When it is
activated, each time the designated lead compressor is
shut off due to the load being satisfied, the lead
compressor or refrigeration circuit switches. When the
RTRM is powered up, i.e. after a power failure, the control
will default to the number one circuit compressor.
Evaporator Frost Control
This input incorporates the Frostat™ control (FOS)
mounted in the indoor coil or on the suction line and can
be activated by closing a field supplied contact installed in
parallel with the FOS.
If this circuit is closed before the compressor is started, the
compressor will not be allowed to operate. Anytime this
circuit is closed 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 open.

Sensors

Note: Zone sensor required for units configured for
Single Zone VAV indoor fan system control to
enable Single Zone VAV functionality.
Zone Sensor Module (ZSM)
(BAYSENS106*)
This electronic sensor features three system switch
settings (Heat, Cool, and Off) and two fan settings (On and
Auto). It is a manual changeover control with single
setpoint. (Cooling Setpoint Only.)
Zone Sensor Module (ZSM)
(BAYSENS108*)
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 BAYSENS075*.
Zone Sensor (BAYSENS110*)
This electronic sensor features four system switch settings
(Heat, Cool, Auto, and Off) and two fan settings (On and
RT-SVX25Q-EN
Auto) with four system status LEDs. It is a manual or auto
changeover control with dual setpoint capability. It can be
used with a remote zone temperature sensor
BAYSENS075*.
Programmable Zone Sensor
(BAYSENS119*)
Programmable Night Setback: Auto or manual changeover
with seven-day programming. Keyboard selection of Heat,
Cool, Fan, Auto, or On. All programmable sensors have
System On, Heat, Cool, Service LED/indicators as
standard. Night Setback Sensors have one (1) Occupied,
one (1) Un-occupied, and one (1) Override program per
day.
Remote Zone Sensor (BAYSENS073*)
This electronic sensor features remote zone sensing and
timed override with override cancellation. It is used with a
Trane Integrated Comfort™ building management
system.
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 (BAYSENS016*)
This bullet type temperature sensor can be used for
outside air (ambient) sensing, return air temperature
sensing, supply air temperature sensing, and 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 (BAYSENS075*)
This electronic sensor can be used with BAYSENS119*
Remote Panels. When this sensor is wired to a
BAYSENS119* 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 (BAYFRST003*)
This sensor connects to the RTRM Emergency Stop Input
on the LTB and provides high limit "shutdown" of the unit.
