Now when I turn on the system, set it all up. It only sets up for heat and not cold. And I got the wires hooked up wrong.</P> Sun, 10 Sep 2023 03:09:24 GMT Mgp 2023-09-10T03:09:24Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Thermistat-only-on-heat/m-p/479108#M103534 <P>I connected the wires like it did to the old one except for the yellow wire.

I'd like to take a closer look at it. A few questions: what&nbsp;<A href="https://goo.gle/3YXHL16" target="_blank">type of Nest Thermostat do you have</A>? In what states are you located? Do you see any messages or codes on your thermostat? Please share with us the photo of the wires connected to your current and previous thermostat.</P> <P>&nbsp;</P> <P>Best,</P> <P>Jenelyn</P> Tue, 12 Sep 2023 16:27:54 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Thermistat-only-on-heat/m-p/479988#M103760 Jenelyn_O 2023-09-12T16:27:54Z
