*Works great: **Fastly.Cool** and Warming environment perfectly controlled. I use 3 in different grow tents. It’s nice to see from your phone how your tent temps are. Does High and Low and records data.*

Do you know if this model can be calibrated? Mine isn't accurate to what the indoor temperature is.

Hello, This t-stat has aux heat which my system also has but you did not address that in this video. Do you know which wires would be used to connect the aux strip heaters or how that would be done?

[luislau]

Thank you sir for this easy friendly block instruction on replacing a thermostat. The thermostat I need and you are recommending is out of stock. What model of thermostat would you recommend me to use instead?

[chuckgrc]

Nice vid, does that model have the ability to set maximum and minimum temps so no one cn tamper?

[jeremyrainwater]

I pressed the two buttons together and messed with the settings. Can you please tell me how i get it set back to out of the box factory?

[YourFriendlyGApilot]

Great video thank you so much for the clear explanation!

Have you ever had to hook the green to a yellow with a jumper wire when Running a WiFi thermostat. With a heat pump

[meganrenaeart]

Hi, can you ever have a two stage heat pump without an O or B wire?

[lhlinn]

Dan, thanks for posting the video. I have a basic heat pump and I want to change the old digital thermostat to a new programmable thermostat. The wiring is very straightforward, except the instructions say a jumper is needed between W2 and E if there is no OD T-Stat. My system doesn't have an OD T-Stat, but the old thermostat didn't have this jumper. Do I need to provide this jumper? Thank you for any assistance.

Im stumped. Trying to install a smart tstat that requires a C wire. Ive got 29V from R to Y, G, O at my tstat. My R to C has 29v at the heat pump unit. I ran a blue wire from the C terminal at the heat pump unit down to the tstat. The other end of the same blue wire that reads 29v at the heat pump only reads 16 to 17v at the tstat end of the wire. WTF? What would cause the wire to lose 10 Volts? Its no longer than 7 feet of length (at least that's the physical distance from the tstat to the bryant heat pump unit on the roof. The connection to the C term is solid. There is continuity. Somehow, as that blue wire is snaking through the drywall down to the tstat it is losing 10 volts. I can't explain that. I tried a different wire, and same result. 17 volts. Makes no sense.

Dan, If I have a common wire and I install a new Honeywell Pro 3000, will it run normally without batteries?

[glennturner]

Hey Dan I have the same old thermostat in my home.
Wires on back are connected as follows, blue to x, white to w2, brown to e, yellow y, orange o, red r, green g.
Do I wire new thermostat like yours as you explained.

[VIDEOHEREBOB]

Did you ever do a 2 stage heat pump that you could share? Thank you.

[imtruth]

"Y" is for the compressor, whether in heat or cool mode. Not for cooling as stated at 7:40.

[jeremyrainwater]

How do I reset my thermostat like this one????

[anonymoususername]

This guy looks like if Tommy Lee Jones did hvac

[awatchman]

My "L" is hooked up. What is it? It has the blue on it which is a reversing valve for heat.
WHAT IS L ? My orange is the reversing valve for cool which is OB on my tstat. Im using 7 of the 8 wires for just a standard heat pump. No indoor unit. what is L ?
