I'm having problems with my tekmar 156 differential controller. http://tekmarcontrols.com/alternativeenergy/156.html After three seasons, the relay seems to be sticking on the "heat" position.
This control is the heart of my system. I need to get something working and fast. A new tekmar goes for about $160. That's allot of money to me right now.
I'm looking at myDTC temp controllers. http://www.mydtcstore.com/index.html
The Azel DST-777 http://www.azeltec.com/images/brochuredst932.pdf
Does anyone have any recommendations on any other differential controllers?
