We installed three Trane 16i 2 speed systems and the owner of the new home owner provided us with the Nest thermostats he wanted to use and they have been running good but we had one system start short cycling and burned up the contactor. We replaced that thermostat with a Trane 803 because it appeared to be confusing the system and causing the short cycling. While there we noticed another stat was warm to the touch and when we killed power to the system and powered back up that system started short cycling.
My question is will the Nest stat work with a variable system or are the controls being disturbed due to the wifi on the nest. Has anyone had similar issues with the nest?
