Jandy Heater Controller TC200 REP R0366200

Match the controller by part number

The listing identifies this item as a Jandy heater controller with model and part number R0366200, plus a TC200 designation. For control boards, printed part markings are usually more useful than generic descriptions such as heater controller.

• Have a qualified person inspect the existing controller before replacement.
• Compare the old unit label for R0366200 and any TC200 marking.
• If your heater uses a different control assembly, this listing does not confirm substitution.

This avoids replacing the wrong board when heaters look similar. Source: Amazon product listing.
