General Control and Sensor Trouble-Shooting Tips:
All of the GoldLine (formally Independent Energy) controls (including C30, CM30, G30 and GL30 series) and some of the Heliotrope General (HG) DTT series controls incorporated the use of 10k sensors. Some of the earlier HG controls and some other lesser known brands used 3k sensors.
To determine the type of sensor, the resistance must be measured in ohms (using a volt/ohm meter) when the sensor is at 77 degrees F. 10k measures 10,000 ohms and 3k measures 3,000 ohms. As the temperature goes up, the resistance goes down.
Resistance can be checked at any temperature, and then
convert the ohm reading measured to the temperature equivalent
by using the conversion chart.
