Hallo !!

I´ve just completed building the AVR-Ctrl board. Everything is working just fine, with regard to the boiler control. But when I want to shut the waterpump off, at a certain temperature, then it fails. The waterpump do not stop, until I press either -/+ in the waterpump mode ! For example I run: Tk-Max 70 and Tk-Min 30 and want to shut off the waterpump Tk < 40 . But the pump continues running. Am I doing something wrong , in the setup ? Any ???

All the best
Carl
