Looking at getting a Google Next thermostat to replace my Honeywell WIFI one.  My question with the Nest plugin, can I change the system setting from heating to cooling using the Axial Control? 

This time of year can get so cold at night to have to use the furnace then the next day have to turn on the air conditioner, back and forth for a few days at a time.  My Honeywell, I can't switch between heat and cooling natively, and try to use IFTTT to set the thermostat from heating to cooling and via versa, but also have to assign a temperature with the receipe, which prevents it from energy savings option. 

I am wanting to use internal Zwave temperature sensors to keep the house pretty much at a constant temperature, whether it be hot or cold outside while at home, and to use schedule while away.
