I have a Pentair Master Temp that runs normally when heating the pool, but when we run it in spa mode the heater will heat for approximately one minute, then shut off for a minute and reignite for a minute repeating the process indefinitely. The pipes do shake briefly, but I have checked my chemical levels and confirmed with local pool store...everything is in ideal range. The thing I'm confused about is why it runs perfectly when in pool mode and not Spa. I checked the flow rate and they were operating at the same rate. I decided to lower the flow rate for the spa mode from 2900 to 2250 and it would only fire for about 10 seconds (maybe less). I then tried it at 3200 and extended the time to about 1:30.
Does anyone have an idea why it's not working in Spa mode?
Thanks for any help.
