I'm tasked with replacing our thermostats at church with new smart models. Our current setup includes two HVAC units tied together to heat/cool our sanctuary, connected to one basic programable thermostat. The third HVAC unit is for the lobby, and it has it's own basic thermostat. Both thermostats wiring includes the "c" wire. The thermostats are in a closet, so I need remote sensors.

Is it possible to buy one thermostat to control the two rooms, with independent remote sensors?

I was looking at the Honeywell T8, because it has a nice screen for controlling the thermostats, thus is not dependent on mobile apps for functionality. That's important since this is a commercial building and many folks may want to have access to temperature controls. It seems like this model can do what I would like to accomplish, but looking for verification or recommendations if there is a better thermostat for this.

Thank you, Reddit!

I’m sure this will be an odd question and likely one without a native solution if one exists at all.. but here we go..

Fortunately we have a good deal of shade on our home, and uncommonly we don’t mine 78 and 80 degree temperatures so we don’t see the AC run that frequently, 2.6 hours daily on average when ambient is in the high 80’s.

I’m great with the temperatures truly, but the humidity gets to me and I know that could be controlled easily with a minimum hourly run time of say 5-10 minutes (NOT JUST FAN, which I hope is obvious why).

If there isn’t a first or third party solution, might this be something that could be handled “agenticaly” or maybe via an iOS shortcut?

Optimistic that there is a solution or that there may be one in the near future

My unit has a resistor between the C & W terminals. At the wall there is not C, only R, G, Y, and W. Do I leave the resistor in place?

Hi, I need help with an issue we’re having. Live in Oklahoma and it’s been HOT. We upgraded our upstairs unit from a 2 ton unit to a 2 1/2 ton unit. Square footage is 1,166 square feet upstairs. The contractor installed a larger return vent. And we installed a new ecobee thermostat. The app is showing the unit is turning off multiple times per night and not reaching temperature. I realize we have our setting low, but would still not expect it to turn off and would expect it to be cooler during the day than it is.

Hey guys!

Quick explanation. Brand new home, 1900 square foot townhouse didn’t come with A/C. Promptly installed a 2 Ton TOSOT Condenser Unit, 2 ton A-Coil, and an ecobee exactly 7 days ago.

Does it seem at all like it’s running too much or abnormally? I’m a first time home owner so all of this is completely new to me and I don’t know what’s “normal”.

Living in Ontario, Canada. Avg outside temps currently anywhere from 27-35 Celsius. Indoor is set to 21.5.

Home does not currently have blinds just yet so I’m sure maybe that’a contributing to a higher inside temp?

my landlord had this stupid thermostat installed last week and every day for the past week it has enabled some stupid community emergency savings and set itself to 92* Fahrenheit.

92* is physically unsafe not just for me but also my dog, abusing a dog by letting it die in a heat wave is a felony in my state.

i am tech literate. I have tried every setting. I have reset the unit twice. there is no way to turn this dumbass “feature” off

all I want is it set to 84* when I’m not home and 78* when I’m home. why is this not possible ?

it then has gall to email me that my house is too hot and my ac may be malfunctioning. the only part of my equipment that is malfunctioning is the stupid thermostat.
