Changing Equipment Type on Nest Thermostat

[Shalston]

When the plumber set up the nest thermostat he set it to the wrong equipment type (heat source: electric, heat type: forced air). It should be heat source:Gas, heat type: in-floor radiant. 

how do I change this?? The kb I found says to use the Google Home app but the options re not in there. Do I have to reset the thermostat?

Thanks.

Assuming your stat is a 3rd Generation , follow this on the display and click continue as you see that.

Settings - Equipment - Pro Setup - Your Equipment Type
