soakinNC Posted November 24, 2022 Report Share Posted November 24, 2022 Hello -- this is my first post after searching on this topic. Bottom Line Up Front: I want to convert my continuous (24/7) circ pump to timer control. Background Older (12-15 yrs) Baja Sportub with circ pump providing suction on separate filter/heat loop (jet pump and jet plumbing separate from filter/heat loop). Everything is 240V -- service comes up thru deck to junction box inside spa cabinet, and then connects to control/heater pack with whip; pack provides power to jet pump, circ pump and ozonator. Circ pump (1/16 HP I think) operates continuosly (unswitched, no topside control), which is annoying (vibration/noise transmitted to house through deck). I'd prefer to run circ/filter mostly at night, and as needed during day to maintain temperature -- I'm considering a control like this: https://www.amazon.com/gp/product/B08VS7SRHN Potential Solutions Install timer between control/heater pack and circ pump (pack still powers circ pump). Disconnect circ pump from control/heater pack and splice to 240V service (with timer) at junction box inside spa cabinet. In either case, the control/heater pack would detect low flow ("FLO") and deactivate heater until flow is restored. Questions/Concerns Would installing timer on the control pack-circ pump circuit stress or otherwise damage the control pack electronics? Would more frequent cycling of the flow sensor (and operating in a "FLO" error state) cause any issues? Anybody tried this? Thanks for your thoughts!

soakinNC Posted November 25, 2022 Author Report Share Posted November 25, 2022 Thanks CST -- unfortunately, I have the "Sportub XS" with the separate circ pump that provides suction on the filter, unlike the (regular old? 😁) Sportub in the manual you provided, which does everything (jets and filter) with the jet pump. http://spaparts123.net/files/2008_Sport_Tub_XS_Owners_Manual.pdf Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted November 25, 2022 Report Share Posted November 25, 2022 Might want to contact United Spa Controls and ask MFG directly if there is a program setting that can be made. Quote Link to comment Share on other sites More sharing options...
