Space Temp Source
–
The source of the controlling space temperature value.
Options:
Sensor Failure
–
No valid space temperature or sensor status = failed.
SPT Sensor
–
An SPT sensor is connected to the controller's Rnet port.
T55/56
–
A T55, T56, or T59 sensor is connected to the controller's I/O terminals.
Network
–
A network temperature sensor is bound to the controller's space
temperature AV.
