So I'm fairly new to Spa ownership, we recently bought a house with a 2015 Cal Spa. I've been trying to prevent it from running every 30 minutes since we aren't currently using it very often. I've done the following 1) Setup a single filter cycle that runs for 30 minutes 2) Set it to Rest mode Low The Spa still seems to kick on in low mode after 30 minutes. Is there something I'm missing? I would have thought that by being in Rest mode AND not currently being in a filter cycle would mean that the jets wouldn't be running. Any ideas? Thanks in advance.
