Nest compatibility

Hello- I was wondering if anyone knew what Nest is compatible with a A/C system and a heating system that has a gas boiler. 2 separate systems....

@sharks1964, 

The Nest learning thermostat series supports, dual fuel systems as such as what you are describing. In your case, you will supply an RC wire from your air conditioning control system and you support a separate RH wire from your boiler control system. As long as your boiler uses a 24 V AC power supply for the control system it’ll be fully compatible with a nest learning thermostat.
