Hi, I have problem with my STM-80 heat pump. Every morning I get error ”Alarm mode, Winter operation, Hot Water demand. Heat pump 1: Blocked, Additional heat: Blocked, T2 Outdoor: 24,5C.
Winter/summer is set to Automatic, and date is correct. What is the problem. And this occupied only if outside temperature in the morning is high, some over 20C.
