EcoBee 3 Dual Fuel

In the spring of 2022, we discovered that the Nest Learning Thermostat was not operating the reversing valve. It had been fine in the fall. The Nest energizes the reversing valve to cool. Come May and time to cool it wasn’t. Oh, and the fall update stomped on the heat pump lockout setting. So the proprietor fired Nest and hired Ecobee.

Church uses a large number of Ecobee 3 Lite devices with extra area sensors and has found them to work well. So Dismal Dave bought one and installed it. It set up easily enough for heat pump operation with automatically configured staging and automatic heat pump lockout and easy configuration of the associated gas furnace. But we had some drama anyway.

Smart Thermostat Upgrade

For many years, a Nest Learning Thermostat has controlled heating and cooling at Dismal Manor. About a year ago, I replaced the Nest Beta program edition with a current production Nest Learning Thermostat. In mid-April, we had a surprise run of hot days so I decided to change from heat mode to cool/heat mode. I made the change, found the thermostat calling for cooling, and hot air coming from the registers. What’s up, Nest!
