Nest thermostat 3rd gen only heating in test mode

Hello!

I installed my thermostat today and ran it on test mode and it worked perfectly. But when I try and turn the heat on with the phone app or thermostat (not hard wired) the heat doesn't come on. Does anyone have any suggestions?

Thanks!

Hdavis248,

you need to supply a little more information in order to get a good understanding and how we can help you. For example, what its the current HVAC system configuration that is to say do you have a conventional air conditioner with a gas, furnace, or a heat pump with auxiliary heating of some sort. How about posting a picture of the old thermostat and its wiring and the Nest Thermostat and is wiring.
