computer control. On WKGD/WKGDX models, converts the temperature
into a resistance valve which is monitored by the temperature control board.
The probe is an RTD (resistance temperature detector) of the Thermistor
type. As temperature increases the resistance value decreases.
On WKGC/WKGCX models, the probe is a J type thermocouple.
