System controller options
Units are available with factory engineered controls as a "plug and play" package. Therefore, the units are provided
with all components including control components (sensors and actuators), controller, and power wiring. In this
case, the unit commissioning is performed by a Trane qualified engineer.

Room temperature sensor
The room temperature sensor should be wall mounted at a height of approximately 1.5 m inside the occupied space
of average zone temperature. Do not mount the sensor near a heat source, door, direct sunlight or in the supply air
stream. It requires a single pair of screened cables.
Return air temperature sensor
The return air temperature sensor should be mounted in the common return air duct, ahead of the fan, so as to sense
average return air temperature. It requires a single pair of screened cables. When possible, the return air temperature
sensor should be fitted onto the return air inlet.
