* Panel with button layout is not compatible.
Jumper Key
J11 If using 3kW or higher wattage heater, jumper can be set in either position, but may perform better on Pins 1 and 2.
If using 2.5kW or lower wattage heater, jumper must be set on 1 Pin only.
J12 Factory set. DO NOT MOVE.
Jumper must be on Pins 1 and 2 for GS51xZ/GS52xZ/GS5xxSZ/GS5xxDZ software.
Jumper must be on Pins 2 and 3 for GS50xZ software.
J43 When jumper is placed on 2 pins during power-up, system will reset persistent memory.
Leave on 1 pin only to enable persistent memory feature.
WARNING:
Setting DIP switches incorrectly may cause abnormal system behavior and/or damage to system components.
Refer to Switchbank illustration on Wiring Configuration page for correct settings for this system.
Contact Balboa if you require additional configuration pages added to this tech sheet.
