Testing went great but not it’s not turning on! It’s 64 in my house. No error code showing up. Fuse box is all good. Wiring is all good according to Nest. I don’t know what’s going on. The unit is only electric. I’ll include pics.

Do you have a heat pump type O heat pump and these types of heat pumps energize the O wire to get Cooling. O models are heating units so you don’t energize the reversing valve. Check your settings of your reversing valve and your nest thermostat equipment, submenu and see that you have a O type and not set up as a B type. Additionally, heat pumps usually use auxiliary heat on very cold days so your white wire should be in the W2/AUX terminal of the nest backplate.

Thank you! I am not sure if it’s an O type or B type. How can I find that out? I’m in an apartment building so I don’t have access to everything but I think the furnace is in my utility room.

On my old thermostat it had a bridge between R and Rc. Do I need that bridge now or is it built in?

I was looking at your pictures of your nest back plate and the problem is it doesn’t look like your yellow Y1 wire or your white W1 wire are fully inserted. The copper needs to go in far enough to cause the push tab in the back to stay down. Your yellow wire is not down. neither is your white wire.

I just rechecked me they are down. I pulled them out and put them back in just incase and they’re definitely down. It does look like in the picture that they are not so good eye!

With the heat pump, we normally recommend putting the R wire into Rc versus Rh. I’m not sure why, but when you have a heat pump, the compressor is always running. For some reason when we start to see some electrical E type errors, when we move from Rh to Rc we see them go away. It should not be that way, but for some reason it always seems to work.

How do I find out if I have a heat pump and aux heat?

You have a heat pump. The blue wire is terminated into the O terminal. Never go by the wire colors, as there is no standard.

Go to you outdoor unit and get me the manufacture label showing the Make and Model number. With that look it on my app a verify it.

I am not sure where that is. I live in a condo building with 7 other units

Hi Rocandrew,
Thanks for reaching out to us. You can find the information of your system through your HVAC unit. Since you live in a condo, you can ask for assistance from their personnel to check further on that.
Thanks for your help, @CoolingWizard and @Patrick_Caezza.
Best,
