Zone Sensor
The controller accepts the following zone sensor module
inputs:
• Space temperature measurement (10kΩ thermistor)
• Local setpoint (either internal or external on the zone
sensor module)
• Fan switch
• Timed override (On) and Cancel timed override
• Communication jack
Space Temperature Measurement
Trane zone sensors use a 10kΩ thermistor to measure the
space temperature. Typically, zone sensors are wall-
mounted in the room and include a space temperature
thermistor. As an option, the zone sensor can be unit-
mounted with a separate space temperature thermistor
located in the unit’s return air stream. If both a hard-wired
and communicated space temperature value exist, the
controller ignores the hard-wired space temperature input
and uses the communicated value.
External Setpoint Adjustment
Zone sensors with an external setpoint adjustment (1kΩ)
provide the controller with a local setpoint (50°F to 85°F or
10°C to 29.4°C). The external setpoint is exposed on the
zone sensor’s front cover.
When the hard-wired setpoint adjustment is used to
determine the setpoints, all unit setpoints are calculated
based on the hard-wired setpoint value, the configured
setpoints, and the active mode of the controller. The hard-
wired setpoint is used with the controller’s occupancy
mode (occupied, occupied standby, or unoccupied), the
heating or cooling mode, the temperature deadband
values, and the heating and cooling setpoints (high and
low limits) to determine the controller’s active setpoint.
When a building automation system or other controller
communicates a setpoint to the controller, the controller
ignores the hard-wired setpoint input and uses the
communicated value. The exception is the unoccupied
