I have an HAI Omnistat model 100 that is not working with our new Bryant Heat Pump. The Elk M1 System is able to see and control the Bryant HP; however, the compressor never comes on (even after 30 minutes).
I didn’t know if anyone had similar issues with the Omnistat/Bryant (I’ve posted a question on their site) or what other thermostats folks are using with the Elk M1 System. I’ve researched the Elk recommended thermostats, but it appears that none have a serial connection.
I wanted to verify before I pull the trigger on an Ecobee3 Lite system.
