Tub Thermal
hot tub jets, high/low timer?

I’ve got a computer controlled hot tub, cal-spa model 2100.

Its jets have three settings, high, low, and off.

On low there’s little jetting, mostly its there for circulation.

On high, its the full hot tub massage relaxing bubbling experience.

So ever since I got this thing, when I turn it on high, after about 1/2hr it turns itself down to low. Is this normal?!? I’m always having to get up and turn it back to high, kinda ruins the experience.

So the tub, its computer controlled by a relay box marked ‘whisper power unit’. I want to modify things so it will stay on high until I turn it off. Any suggestions on rewiring the circuit board or reprogramming the computer?

Don’t worry, the motor has its own thermal control so it will not be damaged by running continuously on high!
