1. Remote panel applications need special consideration where the panels connect to the circuit board If You Are Working on a Spa With a Remote Panel e Before replacing the circuit board or any panel plug each panel into the circuit board directly and individually Test all functions with each panel separately If a Remote Panel Doesn t Work e Remove the remote panel from its location e Be sure to secure the end of the panel cable e Plug the remote panel directly into the board This removes the extension loom with its one to one connector from the circuit board and will help you determine whether you have one panel with a problem a defective gang connector a bad extension loom a bad one to one connector or a circuit board problem e Gang connectors cannot be used on the first three jacks i e on Millennium panel jacks e The first three jacks are functionally identical Try the panel in another one of these jacks e The two aux panel jacks are functionally identical e If multiple panels work in one jack but not another jack of the same set the problem is most likely with the controller board 18 800 645 3201 Panel Messages Panel messages are a quick clue toward solving a variety of problems Here are the most common messages and what they mean The Panel Displays HH GHH or HTR TEMP LMT At least one of the sensors has detected water temperatures of 118 F inside the heater or The Pan2. warm the plumbing The equipment stays on until the sensors detect that the spa temperature has risen to within 15 F of the set temperature The other pumps and the blower will purge for 30 seconds to 2 minutes at the end of the freeze condition If pump 1 was turned on due to this reason alone this message will appear for up to two minutes right after very cold water is detected Note Internal freeze protection only functions when there is proper power running to the spa and the control system is operational Using an optional freeze sensor may be necessary in extreme climates to prevent plumbing damage but will only work properly if placed inside the spa skirt in the coldest area All spa models are different in shape and size and have different thermal characteristics therefore Balboa Instruments Inc cannot be held responsible for freeze damage to the spa s plumbing Testing is the responsibility of the spa manufacturer and must be done to determine the best location for the freeze sensor The Panel Displays iL iL E or FREEZE COND This indicates that the auxiliary sensor detects a possible freeze condition This is a normal spa function no further action is necessary When the auxiliary sensor reads around 40 F actual temperature dependent on specific auxiliary sensor used the system provides freeze protection It automatically activates all of the pumps and the blower to circulate water and warm the plumbing N
