I have a Calypso II spa, and pump #1 is running on low speed, 24/7.
The spa has two large pumps (1 and 2 stage), and a circ pump that is wired into the Ozone accessory.
The Circ pump should run all the time, but not Pump #1.
See page 15 under Jets: http://www.sundancespas.ca/Communications/InstructionManuals/1997650.pdf
Any ideas for troubleshooting? I am wondering if a solenoid may be failing (and how to test it), or if it is the electronics.
