Hello, I live in an apartment complex. Have no access to the Boiler. It's only two wires, that go to a Zone Valve in a Closet. Here's how I installed a Google Nest 3rd generation to a Taco Zone Valve.
The one Transformer wasn't enough to power the Thermostat and power the Zone Valve. So I added...
Running into some complications trying to install a new Nest Learning Thermostat to our old house boiler/radiant heat furnace.
No a/c connection to our old mercury Honeywell thermostat.
The basic question I am wondering: which all wires should show hot/voltage at the thermostat end?
I have a split system 2.5 ton HVAC unit.
I have a NEST thermostat
I started getting error E 183 two weeks ago and the A/C blower shuts off
I tried sending 24 volts straight through the A/C contactor + wire, which I did to test the system when I first installed 6 years ago, and instead of...
I have an A/C unit that is currently wired to my nest thermostat using 4 wires. No Common wire. there is an unused wire in the bundle of wires. Can I simply connect it to C on the A/C unit and then to C on the thermostat to add a common wire?
In a traditional stick built house in cold Maine I wish to install one Nest thermostat and tie it into the Simplisafe system in order to be able to "pre-heat" the house for relative comfort upon arrival in winter. The house has three stories, but it seems clear that the top floor with...
Hi, I have a Nest system with several items on it, and would like to add one or a few light switches that I can control from within the Nest app. I only need basic controls like on-off; dimming would be nice. I don't need hue control or fancier features.
What products do you recommend?
I am still having issues with my furnace and Nests. And I would love some feedback on this one.
My furnace is oil fired, Buderus Logano G115, which has 4 zones and separate hot water unit. The zone relay is an Erie SR-601. I currently have 4 Nest E thermostats hooked into the system...
In relation to this post:
My Erie SR-601 zone relay is now overloading more than ever. It definitely needs more juice to power all the nests. How do I go about adding/replacing the transformer in the relay?

I would like to replace my old thermostat with a Nest thermostat. Could someone please help me figure out what type of HVAC system I have based on this wiring photo? Specifically, I need to know if I should treat the "O/W2" as an O or a W2, the "Y/Y2" as a Y or a Y2, and the "W/W1" as a W or a...
Hoping someone, somewhere can help me with this issue I've been having with my furnace and/or my Nest thermostat.
I bought a house in July 2017. The Nest thermostat was here when we moved in so we learned as we went. This winter, especially this last month, our furnace/Nest has failed so often...

So I had a 3rd Gen Nest installed recently, but I'm having a couple issues:
1. The fan keeps even running after the heat has reached the desired temp.
2. Even with the thermostat set to off, the fan keeps running.
Here are pics of the old thermo wiring and the new Nest.
I'm in a condo so I'm...
I hope everyone is doing well. I was wondering, can I replace this thermostat (Model Robertshaw 9600) with a Nest or similar smart learning thermostat?
Or is the design/technology that I currently have too old?

I have a Carrier system in my home, with 2 remote sensors. 1 of these is the "main thermostat" and the other is a remote sensor. These go to a central Carrier control panel, which goes to the HVAC system, with traditional wiring (Y, C, G, Rh, W, etc.).
The sensors have the following:
