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
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 (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 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, 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
RT-SVX39B-EN
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 (BAYFRST001*)
This sensor connects to the RTRM Emergency Stop Input
located on the LTB and provides high limit "shutdown" of
the unit and requires a manual reset. 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.
Evaporator Frost Control
This input incorporates the Frostat™ control (FOS) located
on the indoor coil 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.
Phase Monitoring protection
Precedent units with 3-phase power are equipped with
phase monitoring protection as standard. These devices
protect motors and compressors against problems caused
by phase loss, phase imbalance, and phase reversal
indication.
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.
