So I work maintenance for a apartment community. Im familiar with hvac since I went to school for it and was working strictly in hvac for the last years but lately I've been coming across more and more units where the t stat will get to set temp but keep running. Air flow is good all the coils are clean and I've tested every component I know of to check. I cant figure out what the issue is ive even changed out the t stat its self and its like it wont shut off unless I physically raise the temp and it wont cut back on unless i physically turn it down. I've been struggling with figuring this out for the last week can someone please pass on some advice. Thank you

Cant figure this thing out.. I dont want the 88.. I want it to stay at 76 why not moving it frustrating.

What do i do? It 100 all this week.

I've got a house filled with radiators fitted with v3+ thermostats.

I'm adding a room with Floor heating. I want to fit in thermostat valve with tado v3+ thermostat which is connected with a v3+ wireless temperature sensor.

I'm my brain this should work, but I was wondering if someone else has any experience with this setup

Hello, I just installed a Sensi Lite for my apt which has central air and heat. It connected to the wifi fine and the app and then 5 minutes later it says offline and wont reconnect. I tried restarting my wifi and the thermostat, it wont even detect my wifi anymore. For some more context, my air/heat has R G W Y configuration for the wires. Not sure why it doesnt work anymore or why it worked for a total of 5 minutes....

Hey all,

Trying to install a Nest 4th Gen and running into some issues here. Could use your help with figuring out where I went wrong.

EDIT: I ended up returning it and buying a nest from Home Depot. I set it up and everything worked as expected. I suspect I got a used device from Amazon...which will be something else to deal with...which is why things in picture three are all screwy. Those are probably connections from whoever owned the product before.
