Heat Pump not staying on to heat up the home? Here is the original wiring diagram. Wiring configuration for Nest Thermo - heat pump runs but no heat? When I look at the wiring attachment on the program it states no W white wire attached even though it is. What does the white wire do?

All 6 wires are attached to their respective posts. The problem is that the white wire doesn't show connected on the nest app / google app. It doesn't show emergency heat either as an option under 'equipment'. I would think the white wire was for the emergency heat option.

My wiring does look a little ragged so I'm going to recut them and retry it.

I'll let you know...thanks for your timely response.
