Nest - Emergency + Aux Heat

[windsurfnut]

Nest Learning Thermostat

Bosch IDS 2 Heat Pump System with 15kw heat strips

When engaging Emergency Heat on a Nest learning thermostat, will AUX heat come on/off as needed to supplement the emergency heat?

On my heat pump system, I have a 15kw electric backup strip.  Its actually a 10kw+5kw strip.

Currently its wired with the 5kw strip as AUX(W2/AUX) and the 10kw strip as Emergency(*).  Both operate as they should, AUX (5kw) comes on to assist the heat pump when needed, and Emergency(10kw) is enabled when triggered when called on.  

My question is, will the NEST call on (5kw)AUX in Emergency Heat when needed to supplement the 10kw strips?
