The LX-15 Alpha-Numeric Topside replaces all LX-15 systems made by Spa Builders Systems/Support Group, comes with 4, 5, or 6 buttons to control up to 2 pumps and blower and a light with LED readout for temperature. (note that replacements are for program chips of 5.31 and higher, if you have a lower chip then call for replacement.)
Be sure your circuit board has REV 5.31 sticker on it that indicates it's the later version. If you have anything different, you must call us for the correct topside panel replacement solution.
Note the LX series of controllers are obsolete and availability of topsides is limited to stock on hand.
