Wiring Diagram
The following wiring diagram displays a controller with 3 separate inputs from the sensor:
Temperature, Setpoint and Override. In this instance the jumper on the RTS-20JPS should
be set to the middle Override position. The controller in this instance has the Temperature
connected to Input 1, the Setpoint connected to Input 2 and the Override signal connected
to Input 3. If the controller requires separate Ground connections for each input, connect
the Common from the RTS-20JPS to each Input ground terminal. The labeling on the
backplate of the RTS-20JPS is labeled: TMP for the 10k Thermistor, SET for the 20k
Setpoint adjust potentiometer and OVR for the Override input.
