Well, you have the wiring diagrams. I don't know what else to tell you on that subject. If you are unsure about reading those, find someone who is more familiar. Did you connect the neutral wire to the output? Now for the help on what can also be the problem.. did you program it correctly?



You should select the setpoint (highest desired temp of whatever you want the sensor to see), select the differential (anything from 2-4 deg is good for most apps, you can fine-tune this later), and then select "h" for heat control. This way, the output will turn off at the setpoint temperature, and not turn on again until the sensor sees the setpoint minus the differential.



Example: setpoint set to 82 deg, differential set to 3 deg, mode is "h" - the heater will be ON until the sensor sees 82 deg. Then the heater will go OFF and stay OFF until the sensor sees 78-79 deg.



If you have mode "c" selected for cooling, the logic is reversed and will give you strange results unless you are using the device to turn on an air conditioner.
