General Information
Remote Zone Sensor (BAYSENS013C)
This electronic sensor features remote zone sensing and timed override with
override cancellation. It is used with a Trane Integrated ComfortTM building
management system.
Remote Zone Sensor (BAYSENS014C)
This electronic sensor features single setpoint capability and timed override with
override cancellation. It is used with a Trane Integrated ComfortTM 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 (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 equivalent). Refer to the
specific Remote Panel for wiring details.
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 approximately 25°F below the
cutout setpoint.
Evaporator Frost Control
This input incorporates the Frostat™ control (FOS) mounted in 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 5 continuous seconds
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.
