1. One of the sensors has detected the temperature of the water coming into the heater to be 110 F and so the water in the spa is likely to be that bot These indicate that the spa has shut down due to an overheat situation Note Overheating may occur if the low speed pump is set to operate for extended periods of time or if the incorrect pump is installed In rare cases usually warmer climates the circulation pump may also cause overheating The following is a list of most probable causes of this message Inspect these first e Check slice or ball valves Make sure that they are open e Make sure the correct pump is installed e Clean the filter skimmer if there is any blockage e Check heater element alignment e Check for debris on the heater element e In extremely hot weather check for proper cabinet ventilation e Make sure the temperature sensor is fully inserted into the sensor fitting on the heater e Check for excessive filter duration Note A common programming mistake is overlapping filter times that may cause the spa to filter continuously e Check the water level e Check the water temperature with an accurate temperature thermometer Remove the spa cover and allow the water to cool to below 108 F Adding cool water may be necessary Touch any button to reset the system If the water is still hotter than the set temperature press the blower button if applicable to cool the spa2. www balboa instruments com 29 Dip Switch and Jumper Settings Jumper Function of Jumper Position J6 Selects circ non circ pump option pa Non circ pump selected J 7 Selects top side panel being used pa Deluxe panel selected J 9 Selects 120V 240V logic g 240V logic selected J 10 Selects 1 or 2 speed pump 2 operation Da 1 speed operation selected J 16 Enables O message Da 0 message disabled J 24 Disables ORP g ORP disabled J 25 Selects 50xz C 60rz F operation Ba 60hz F operation selected J 36 Allows memory storage and resets memory 8 Memory storage allowed J 41 Disables pump 2 pa Pump 2 enabled Portion of PC board The Jumper symbols shown here are oriented to correspond to their actual for Elite showing positions on the printed circuit board location of jumpers DO Open Jumper 00 Shorted Jumper DGC Selectable Function Jumper J 36 J7 J16 J 25 J10 J6 J4 J 8 J 24 a lt H N iat 34 air ad Pr j RIT j gt RISC gt M 20 j f Qe adie eee ey E 4 dt dd vit d dk lt oe 30 X 800 645 3201 SUV Circuit Board roa ry a Teal 7 ir 7 SAO ee 1 M O ene ta a yi Te Coa LA L 1 a J we TOW A ig I i li I I i L 4 ee md l D L i 1 i Pump 2load I g i no blower fuse p 1 required J ys H r e e e e e E a e E 25K GUASS O 1 S Teie al 8 _ mam

Perform the following sequence of tests Test the System e Turn the power off e Be sure to replace the system power input fuse with the same type e Unplug the blower and all pumps e Restore the power and verify system operation e If the fuse blows then re check the internal system wires and connector for burns cracks or cuts in insulation e If the fuse does not blow turn the power off and plug in the pump Note Be sure to test each device individually Test the Pump e Restore the power and activate the pump e If the fuse blows there is a pump problem e If the fuse does not blow turn off the power Test the Blower e Plug in the blower e Power up the system and activate the blower e If the fuse blows then there is a blower problem e If the fuse does not blow the combined pump and blower amperage may be excessive To verify this first check with your spa manufacturer for amperage draw limits on each device e Since the blower should now be running you can check the amperage draw with an ammeter by measuring around the black blower wire and compare with manufacturer s specifications Test the Amperage Draw e Turn off the power disconnect the blower make sure the pump is plugged in and restore power e Start the pump and switch to high speed if available this should draw the most current e Make sure all jets and valves are open e Check the amperage at the red pump wire Compare yo
