Hello all,
I bought a used hot tub that didn't come with any manuals. All companies that are somewhere on the hot tub are out of business. There is a switch, the one the green arrow points to in the pictures below, which puts it in Winter or Summer mode. When in Winter mode, the pump and heater only turn on when the temperature drops below the selected set point. When in Summer mode, the pump stays on continually, and the heater only turns on when the temperature drops below the set point. I would think that this is backwards, that you would rather have the water recirculating all the time in the winter but not needed to in the summer. I have Googled for this, but have come up empty. Do you all have any idea if this switch is functioning correctly? If it is functioning correctly, why would you want the pump to run continuously in the summer but not in the winter?
Thanks in advance.
