Sundace 680 wiring

Please confirm what is required in order for the hot tub to heat while both jet pumps are running in the high speed. Tub service is a 4 wire 50 amp GFI. Assuming jumpers in the control box need to be changed to energize the heater while both pumps are running in the high and is a 60 amp breaker upgrade required? Thx

  1. Troy to obtain 60 amp logic you need a 3 wire and a 60 amp gfci. Once you have that in the jumper settings to setup 60 amp logic are on page 48 of your Sundance 680 series owners manual. If all else fails contact our Service Support Desk to book our licensed electrician to hookup to run on 60 amp logic.
