Winter SPA

[Kwiatjk]

I have a spa with frost protection. However, it works by raising the temperature to 9-10 degrees Celsius.
Is there any way to change this with this module? For example, to only maintain 2 degrees Celsius? The goal is to reduce energy consumption.

It depends. The module has it's own frost protection (not guaranteed to work if it crashes or have bugs etc) but I think the 6-wire versions pump will override it if has a higher minimum temp. You cannot set the temperature any lower than 20C but you can turn off the heater and start it at a set point, which is how the ESP antifreeze works. The 4-wire systems may be possible to trick if the logic is in the display part of the pump. Most functions are but I don't know about the frost protection.
It might be more expensive to go near the freezing point than the savings made. Maybe some parts are colder than where the thermometer is located...

made. Maybe some parts are colder than where the thermometer is located... last year i disconnect power and after winter all was ok ;-)
