How is the ambient temperature measured if a zone has both a Sensor / Sensor PRO ambient temperature sensor, code 215001/215001 BLK / code 215002/215002 BLK, and a Comfort Control electronic control, code 215510/215510 BLK?

If one or more Comfort Control electronic controls and a Sensor / Sensor PRO ambient temperature sensor are installed in the same zone, the temperature detected by the ambient temperature sensor overrides that of the electronic control.
