I'm a homeowner an Elk M1G installed myself in 2009, with the serial interface and HAI Omnistat thermostat. Recently I had the 30 year old furnace replaced, and coincidentally the thermostat stopped working. The furnace contractor confirmed it stopped sending the call for heat to the furnace, which is really important for a thermostat to do. It's too coincidental that it would happen simultaneously, but whether it was the furnace installer or not, I still don't have a working thermostat.
Since my original install, HAI was acquired by Leviton. I purchased a Leviton Omnistat from Amazon, and when it arrived and I connected it, it was faulty. The LCD screen was garbled, and would freak out every time you turned the control dial. I returned it to Amazon for another, which was also faulty. I returned them both to Amazon for a full refund. Clearly the quality under Leviton is not as good.
Before returning to Amazon, I did try to resolve it with Leviton. Leviton was completely useless, not returning calls, no support. I have no confidence that Leviton actually makes a working product. So I need to know what alternatives there are.
I'm trying to stay with thermostats that use the M1 serial interface, because I have an existing investment in the serial interface. I don't have a Zwave in this house. This is a vacation home, so I need something very reliable. But if ZWave is my best most economical option, I could go that route.
Thanks for the advice.
