ETI TRACON – GPT 230 FAQS

HOW DO I SET UP MY GPT FOR AN RTD SENSOR?

The GPT unit comes with a thermistor (two thermistors with the GPT 230) but is also compatible with a 3 wire RTD sensor. The diagram illustrates the correct wiring and DIP switch configuration for each temperature sensor wiring scheme. It is important that you also navigate to the Sensor Type screen and select the type of sensor being used. * The GPT comes set up for use with the provided Thermistor sensor.

The provided thermistor sensor will work for heating applications where the operating range is between -40°F and 230°F (-40°C and 110°C). For applications that require a larger temperature range an RTD sensor is needed. With an RTD sensor and the GPT 130 or GPT 230 you can accurately monitor and control for temperatures from -99.9°F to 999°F (-73.3°C to 537.7°C). Tank heating, water basin heaters, immersion heaters or any heat trace application.  For more information about installing a  3-wire RTD sensor or the provided thermistor consult the GPT 130 or GPT 230 manual or installation guide.
