First, take a moment to familiarize yourself with the heater wiring and inside of the controller. Match the labeled components in the photo to what you see on your heater and in your control.
Once you have located the protector lead wires and terminal block inside your control enclosure, guide your lead wires (power, protector, ground) in through the hole that you knocked out for the heater wiring and secure with conduit fitting.
Using a small flat head screwdriver, press down into the hole above terminal #4 until you feel a slight click. You will then insert one of the prepared protector wire ends into terminal 4 below. Once fully inserted, remove the screwdriver to secure the wire. Test the connection by pulling on your wires to make sure they are securely set in the terminal block. Repeat this process with your second protector wire.
