## Questions & Answers

**Q: Why no W terminal?**
A: the stat is a heat pump stat   will adapt for other applications  
in a heat mode on a Carrier heat pump O/B is not powered and Y takes the place of W1or W{same terminal } G is powered to operate the fan W2 is electric heat The first stage of heat is the "Y" energized and heat from the outside air and compresses motor heat second stage heat is W2 , W2 is also powered in stand alone for emergency heat or electric only heat when temp gets extremely low and you don't get an advantage of heat from outside air 

R,C,W2,E,Y,O/B,G,L.
R 24vac
C common
W2 electric heat
E  emergency heat
Y compressor run
O/B heat /cool electrical selector 
G fan 
L   I don't remember the use of this terminal  see installation instructions for application if you decide to get this thermostat

**Q: Does this work for a geothermal heating & air conditioner system**
A: would need to know more about the requirements that your system this stat is 2 heat stages  first is heat pump heat  the second is heat pump heat and restive heat ,, single stage cool , our stats have been in operation on conventional heat pump air to air units for over a year with no problems,,

**Q: can the 2nd stage heat (emergency) be prevented from kicking in if set only to heat and not auxiliary?**
A: You can set it to “slow” which limits it but does not prevent it from coming on all together. The only way I can think of locking out w2 with this thermostat would be to leave that wire disconnected.

**Q: My heat pump unit has 7 wires, red,blue,green,white,yellow, orange and brown. with a jumper for connecting r and rc. will this thermostat work for me?**
A: yes

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good replacement for factory American Standard Thermostat
*by K***. on November 5, 2024*

We had a thermostat that was replaced under warranty approximately 5 years ago. When that factory American Standard Thermostat was installed, we didn't know it was newly manufactured in 2004! So, when we needed a new thermostat I decided not to bother with a super expensive one and to go with an acceptable substitute. This fits. It's worked for the past 3 1/2 months and it was simple for a handyman to install and to use.

### ⭐⭐⭐⭐⭐ You won't be regret !
*by O***N on August 26, 2020*

If you have a heat pump AC, this thermostat will make you very happy. I bought in early June but didn't replace my old one until early August because I was afraid to mess it up, I took photos of the old one (Climatouch) wiresTo make sure I have the right connecting terminals which I have5 wires, red, blue, white, green, light red.Very fortunate I see the same color wires in this new one, took the old one off the wall, place this new one in，Turn the power on, bingo! Sounds easy? But I spent more time to figure out how to screw the thermostat into the wall because my old one has a bigger hole :( anyway, I gave myself a pad 9n my back, all my worries has been overestimated! Effect? This new one is very efficient, it maintains the room temperature whenever the room is getting hotter, the result is a very comfortable atmosphere all day and night! More frequently to kick on but much shorter period of about 5 min vs 20 min of my old one which won't kick on until there was a 2 degrees differential between the setting temp and the room temp, sucks! Go ahead, but this one if you have a heat pump ac, you won't be sorry :) by the way, I just received my electricity bill, there are 2 weeks of using this new 9ne but my bill is the same!

### ⭐⭐⭐⭐⭐ Great replacement
*by D***F on March 20, 2021*

Had to replace an old digital thermostat on a Rheem heat pump. Watched a few youtube videos to see if it was something I could do and it was. One important tip was O/B connection. Most have orange wire, mine had blue (Rheem) so you have to flip a switch on the board to let it know which you are using. Also, in installers setup menu you have to set the compressor lockout as it defaults to no delay. My old thermostat had a built in 5 minute delay, so I had to turn it ON with the Emerson. The other thing to watch for is the W2/E jumper. The instruction book is very helpful, better than most, but check what you have on the old one before disconnecting the wires. With my notes from the videos and my hand written diagrams I was ready. Everything went as planned. The test section in the manual confirmed everything was working correctly. It has been more than a month and so far no problems, heating or cooling.
