BAS-SVU10C-EN 5
Product Overview
The Trane Communicating Heat Pump Thermostat is specifically designed for control of self-
contained heating/cooling heat pump units. The product features an intuitive, menu-driven, back-
lit LCD display, which walks users through the programming steps, making the process extremely
simple. Accurate temperature control is achieved due to the product’s PI time proportional control
algorithm, which virtually eliminates temperature offset associated with traditional, differential-
based thermostats.
Two digital inputs can be set by the installer to monitor filter
status, activate a remote temporary
occupancy switch, and/or used as a general purpose service indicator.
Three remote sensor inputs are provided: Remo
te room or return air temperature, outdoor air
temperature, and supply air temperature for monitoring purposes.
An SPST auxiliary switch output that operates with the occupancy can be used to control lighting
or disabl
e the economizer minimum fresh air function.
The thermostats are also compatib
le with the occu
pancy sensor cover accessories. Thermostats
equipped with an occupancy sensor cover provide advanced active occupancy logic, which will
automatically switch occupancy levels from Occupied to Unoccupied as required by local activity
being present or not. This advanced occupancy functionality provides advantageous energy
savings during occupied hours without sacrificing occupant comfort.

Theory of Operation
The Trane Communicating Thermostat uses a proprietary adaptive logic algorithm to control the
space temperature. This algorithm controls the heating / air conditioning system to minimize
overshoot while still providing comfort. It provides exceptional accuracy due to its unique PI time
proportioning control algorithm, which virtually eliminates temperature offset associated with
traditional, differential-based on/off thermostats.
