Turn off automatic safety feature on a nest thermostat. House shut down for winter.

[NeilMAR]

House was shut down for winter.  All pipes drained , heat shut down.  Heat thermostat is off no power to it 

however, even though air conditioner units are off the nest thermostat has an emergency feature that tries to turn on heat of house goes below 40 degrees..  one air conditioner unit turned on and seems to have activated a heating section because temp went below 40 .

is there anyway to use the app to disable this feature?

thank you

I'm not sure of the situation, but any insulated house is going to need to be heated, otherwise the mould and condensation will start and by spring there will be a big mould problem. That's the reason that feature is there.
