It’s always best to send the back connector board with the controller unit, and there’s no extra charge for working on it. Removing the back connector board is easy; you just need to keep track of the wires and where they go.
Use the steps below, or watch this video.
- Just loosen the screws holding the wires, slide them out, then simply remove 4 “Philips” screws that hold it into the case.
- Do not remove the entire case (it’s too much work), just the yellow or white connector board with all the screw terminals.
- Here are some tips on removing the back connector board
- Always disconnect power first, or at least remove the red and yellow 24VAC wires first and cover each end with tape so they do not touch each other or anything else while you work. This protects the transformer from shorting out
- Take a picture of the wiring or label the wires before you remove them, Use it as a guide when you hook it back up.
