Nest Learning Thermostat (3rd Gen) Wiring

[MarkZ79]

I have a WaterFurnace NDV049 Envision geothermal heat pump. Below is the wiring for my previous t-stat. How should I wire the NLT (3rd gen)? I've tried a couple different things but it doesn't seem to be getting power. When I place the display on the base, the display doesn't come on.

Hi Markz79,

Thanks for reaching out. I understand you need help connecting the wires on your new NLT. No worries, I'm here to assist you.

Could you please send me a picture of the wire connection from your previous thermostat? This will help me verify the wiring and explain how to connect the wires on your NLT.

I look forward to your response.

Regards, 

Manuel

The image of the previous t-stat's wiring is in the original post. 

I have it working now. A fuse on the heat pump control board was blown.
