New Mastertemp operating question

[JamesW]

Do you have a picture of the entire system?

Is the water temperature accurate the whole time?

N,

I believe the way this automation works is that it will call for heat as soon as you go into the spa mode unless "Spa manual heat" is checked...

Could be a bad board, but it works in pool mode, so that is odd.

Think next step is to reset back to factory settings (if possible), and set everything up just in case something was checked inadvertently.

Temperature between Heater & ET read same. Think I may try Erase EEPROM as last resort.
