Installing a programmable Wi-Fi thermostat on a heat pump

I've been told installing a programmable Wi-Fi thermostat for a heat pump is not a walk-in-the-park the first time.

Could you review my summary of Honeywell's installation steps and function and option settings and let me know if I am missing anything?

Thanks!

Old Thermostat: Honeywell TH3210D1004

New Thermostat: Honeywell RTH6580WF1001

1. Switch OFF power to the heat pump system at the circuit breaker box.

Is there any reason to remove the two pull-out disconnects located on top of the air handling unit?

2. Remove the old thermostat faceplate and take a picture of the wire connections for later reference; see below. (The old thermostat operated without batteries despite having a place for two AA batteries.)




3. Label wires by terminal connection.

I am planning to skip this step given the correlation of wire color and terminal designation recognizing that the black wire goes to the C-terminal.

4. Disconnect wires from connection block and remove old wallplate.

5. Separate the new thermostat faceplate from its wallplate and mount it on the wall.

6. Connect the black wire to the C-terminal and the remaining wires as shown in the photo above.

7. Attached faceplate to the wallplate.

8. Switch ON power to the heat pump system at the circuit breaker box.

9. Set clock to current day and time.

10. Set functions and options: For heat pump systems, follow instructions on pages 18 and 19 (see attached) to change the system type by setting System Function 1 to match your thermostat to your system type.

Please review: I highlighted what I think are the correct settings on pages 18 and 19 (see attached).

11. Test thermostat per instructions.

12. Setup Wi-Fi per instructions.

 

Not sure what you picture is depicting there.
Typically you take a picture of the wiring ON the old thermostat and then post that picture.

Based on what you are illustrating.....
Black >>>>> C
Red >>>>>> R
Yellow >>>> Y
Orange >>> O/B
Green >>>> G
White >>>> AUX

1 >>>>>> 5 - heat pump with back up heat
2 >>>>>> 0 - orange for cooling/standard - reversing valve
3 >>>>>> 1 - electric heat - stat controls blower
5 & 6 >>> 9 - electric heat response
The rest are your choice.
!2 >>> I'm not a big fan of auto heat/cool changeover especially where temperatures can change drastically like in the spring and fall.

 

The top is the old wallplate "mapped" it the new wallplate on the bottom.

 

Still does not make sense?

No problem we're good. What I left you is applicable to your install.

 

Pete,

You have been a tremendous help!!!

Thanks, again!
