Abstract
A dual probe interactive, control system for accurately controlling the temperature within a specified area has a controlling temperature probe located for fast response times and used in association with a controllable setpoint for modulating a heating/cooling source. An indicating/reference temperature probe is also placed in the same enclosure at an optimum location for indicating actual temperature. The actual temperature is compared to the desired temperature to detect any droop or offset and the controllable setpoint is then adjusted accordingly.
