Evaporator Frost Control - Trane YSC037E Installation, Operation And Maintenance Manual

40% and 60% by adjusting the DEHUMID setting on the
ReliaTel Options Module. See
Duct Mounted Relative Humidity Sensor
(BAYSENS037*)
Field installed, duct mounted humidity sensor is used to
control activation of Enhanced Dehumidification and the
hot gas reheat dehumidification options. 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
Programmable Zone Sensor - (BAYSENS119*)
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
º F .The heating set point ranges between 43 and 96ºF .
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 (4) operating status
signals from the RTRM (HEAT, COOL, SYSTEM "ON" ,
SERVICE).
Four (4) wires from the RTRM should be connected to the
appropriate terminals (7, 8, 9 & 10) on the ZSM.
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 aTrane 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 electronic sensor can be used with BAYSENS106*,
108*, 110*, 119* Remote Panels. When this sensor is wired
to a BAYSENS119* Remote Panel, wiring must be 18 AWG
ShieldedTwisted 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.
Electromechanical Control
The unit must have a thermostat to operate.

High Temperature Sensor (BAYFRST001*)
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 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 (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.
