Waited all week in the cold for a new controller so got fed up yesterday and pulled the old one apart, a touch screen (lesson no 90 for me) cleaned it all inside and out, new batteries in , program morning and evening operation for the Hydronic System with a Gas heater on the outside wall. Eureka moments followed and we are now warm. It has been erratic since new but now follows instructions. Three hundred dollars better off yipee.
