But, without a g wire, nest will not be capable of control the fan unbiased of heating. Not unusual cord (c) no longer required in maximum cases, however strongly endorsed. Use rh or rc in single transformer structures; no jumper twine required. For twin transformer systems, use rh for the heating transformer and rc for the cooling transformer.

However, with out a g twine, nest will now not be able to control the fan independent of heating. Not unusual wire (c) now not required in most instances, but strongly encouraged. Use rh or rc in single transformer systems; no jumper wire required. For twin transformer structures, use rh for the heating transformer and rc for the cooling transformer. Nest gaining knowledge of thermostat set up & configuration manual page 9. 23 the way to quick reference manual action steps configuring nest for the installation location and hvac machine just after set up, nest will manual you via a fixed up interview, wherein you will configure it for the heating and cooling gadget it s controlling and for the home or commercial enterprise where it s set up. To help with hvac configuration, nest automatically and electrically detects the wires inserted into its press connectors. While nest senses which wires had been related to its base, it will automatically configure its software program for the device kind it has detected. For instance, if it s a heat best machine, nest gained t show any cooling alternatives. If it s a heat pump, nest will realize and do a special check to check the orientation of the o/b wire. The installation interview will even manual you through connecting to the purchaser s wi- fi network, organising the place through zip code, and organising if the region of installation is a domestic or commercial enterprise. All of this statistics helps nest to build a agenda this is best applicable for the patron s needs. Use pro setup to configure nest to govern your consumer s hvac gadget. Pro setup permits specialists to configure how nest controls every twine related to the bottom. Using seasoned setup is needed to whilst the use of nest with dual gas systems (e.G. Heat pump with furnace), humidifiers and dehumidifiers. Pro setup is handiest available with the second technology nest gaining knowledge of thermostat. Pro setup additionally offers configuration choices for other sorts of structures such as two-stage warmness pumps and emergency heat. It's far to be had to installation professionals at some point of and after installation and lets in them specify how nest have to control the precise hvac system getting used. Research more approximately pro setup, please go to: testing the primary operation after installation spark off heating and cooling simply turn the ring to set the modern set point above or beneath the modern-day ambient temperature within the room. You ll need to interchange to and from heating and cooling modes as you do this. Switching modes to exchange to and from heating and cooling modes, observe those steps: press the hoop to carry up the menu. Pick out the pink and blue dots. Flip the hoop to pick out heat or cool. Press the hoop again to pick. Be aware: to defend the heating and cooling systems it controls, nest s minimal on-off instances for guide temperature adjustments are 2.5 mins for heat pumps and air con systems.
