When your system calls for heat, does the heat pump start running? (The compressor should hum, and the condenser fan should run.)
Check this 3 amp fuse.

Thermostat wiring looks ok, what’s the wiring in the furnace/ air handler look like?
Been helping @Rulwiz on installation of his T-Stat on a Heat Pump. The device does power up and seems to run. However, @Rulwiz , please update if incorrect, when on AC the unit seems to blow warm air not cold but the heat will blow heat. I have asked to get a picture of the control board to see what the HVAC looks like as well as the model of the HVAC. Below are some images, the first one I think could indicate why this is as the Cool Stage has an X on it as does the Heat Stage 1.
One of my recommendations is to reset the T-Stat and set it up again. However, during setup, I recommended to ensure that Heat Pump and forced air is selected.
Any assistance or recommendations you would have for @Rulwiz would be appreciated as you are more versed in HVAC than I am.
The following images are being provided to show what the Wiring was and how it is hooked up now:
Based on the Wiring and reviewing what Wyze Recommends for Heat Pumps as well as the HVAC model indicated (Model: REM4P2400AL), to me it looks like it is wired correctly at the T-Stat, but I am sure you would know better. Here are a couple of images which is what I am basing my opinion on:

The lack of cooling indicates that the compressor is not being turned on when a call is being made. Some compressors have energy saving devices that can introduce up to a 5 minute delay between the call for cooling and the actual startup of the compressor. Make sure he’s running it for at least 10 minutes before checking for cool air. The heat will still operate, but only in stage 2 mode if this is the case.
Thanks, I will check to see if it is on and if he notices any difference. But why would the test show 2 our of 3 tests failed. Confusing. BTW: I tagged him in my post above.
If the compressor doesn’t turn on, both stage 1 heat and all cooling will fail, because stage 1 heat on a heat pump just runs the air conditioning system backwards, with the outdoor coil getting cold and the indoor coil getting warm.
Makes sense. I posted the question and asked that he turns the T-Stat down to allow the AC to kick on and then go outside and see if the Unit is on. Hopefully they will respond.
You think it would be beneficial for them to redo the setup and make sure they selected the correct Furnace type: Heat Pump and Forced Air
it shouldn’t matter, the presence of an O wire should be enough to tell the thermostat that it is connected to a heat pump.
Thanks. That is what I thought as well.
You should go outside to the compressor and make sure both the condenser fan and the compressor are running during the call for stage 1 heat and cooling. The compressor generally has a pretty noticeable hum, and the fan should be spinning. During the cooling cycle, hot air should be coming out of the fan, and during the heating cycle,cold air will come out.
Nothing pops out at me.
try checking the fuse?
For troubleshooting, if you use a jumper or paper clip or anything metal really and connect the W terminal on the furnace to the R terminal, does it start trying to heat?
