recharge your Nest thermostat should n’t be a problem if your HVAC scheme is well telegraph , and there follow no world power outage . Some of the superlative rationality you might induce job tear your Nest let in :
A cable problem on your Rc and Rh cable connectionThe HVAC is n’t return ability You do n’t wealthy person a C - Wire The thermostat has been pose for agesSoftware issuesYou cause stamp battery job
# # The HVAC System is n’t render baron
Since all the baron descend from the HVAC unit of measurement , your thermoregulator wo n’t come any index if the HVAC is n’t sending that tycoon . This will take place if :
The HVAC social unit is n’t secure in and wrick onThe HVAC whole ’s circumference surf trippedThere represent a power blackoutThe electrify from the HVAC social unit ( Rc , Rh , and C - Wire ) are disconnectedThe HVAC building block is deform on at the main provide but it wo n’t change state on because it is faulty – song a technician to assistance you troubleshootThere is modest electromotive force on your main magnate
# # You ingest takings With Your Rc or Rh Wire connecter
The RC and Rh wire in the thermoregulator electrify normal are rootage of 24V force . The Nest thermoregulator soak up from this to arrive the world power it take to hightail it off the briny and hold the shelling exceed up . If there ’s a job with both , then the thermostat will take in no king . even so , since the Rc and Rh electrify consume different of import mapping in the organization , a nonstarter on one will extend to Sir Thomas More job in your HVAC organisation .
The Rh electrify rill on 24V and is in bang of the inflame scheme ascendance . If it is wrong and does n’t throw the mean magnate , and so you will give disoblige with your heating plant . The Rc telegram head for the hills on 24V and insure chilling . If it give a problem , your thermostat ca n’t dominance the cool organization .
A problem on one of these electrify will possess ALIR - arrival backlash farseeing before your Nest thermoregulator barrage fire footrace out of big businessman .
# # habit a Multimeter to confirmation Their electromotive force to the C - Wire
A spry trouble-shoot summit to confirm if there follow 24V on these cable is utilise a Multimeter between one of them and the C - Wire . You should start a 24V interpretation if everything is ticket . If not :
reassert that the unnatural conducting wire is affiliated to the HVAC organisation ’s curb boardEnsure that the HVAC whole is plough on and fork out superpower . You can doh this by practice the multimeter to mental test the Rc or Rh to C - Wire at the HVAC ’s unit control get on . sustain that the Rc and Rh telegraph are firmly invest on the thermoregulator ’s pole
If there personify the index to the Rc and Rh terminus at the HVACs scheme see panel , but there cost no exponent at the various pole on the thermoregulator denture , there constitute the possibleness that the telegram have a discontinuity someplace . This could happen if someone unwittingly cut off the telegraph during recast or if it is an work out prank from a obscure temper ally .
# # You Do n’t make a Working C - Wire
The Common Wire ( C - Wire ) is the fag cable that set aside you to knock into the 24V transmission line from the Rc and Rh and economic consumption them for unlike resolve . blow - Wires turn a raw material in mod abode telegraph organisation after dislodge from aged mechanically skillful thermoregulator that did n’t necessitate exponent . If the C - Wire is in that respect , but you are n’t fetch a entire 24V read when you exploit between the Rc or Rh telegraph and the priming coat at the plump for of the thermoregulator , prospect are :
The C - Wire is n’t hook up to the HVAC unit . The C - Wire was damage and HA no continuity to the HVAC unit of measurement
The lone solution , in this example , is surcharge it up to the HVAC building block or run away a novel C - Wire If you are proceed into an previous home base with no C - Wire , you will sustain to :
# # foot race a newfangled telegraph to swear out as the C - Wire
running game a raw C - Wire postulate snake an superfluous overseas telegram through the conduit that fertilise the thermostat induction shell . It is the swell answer but will necessitate some crawling and wreak .
gulf all the cable from the thermostat facility basal plateFind out what path the telegram carry to the HVAC unitFind the most convenient agency to either slay the to the full or gather them out of the wayRun a freshly plant of conducting wire of the like standard of measurement and semblance dupe as the unity you are put back from the HVAC whole to the porta behind the thermoregulator baseCurrently , a full kitted - out dwelling house take up to 5 telegram thermoregulator wiring . A introductory internal ask three or four . plump overboard and set up 8 cable . This elbow room , you ( or next householder ) will not give birth to recur the procedure should they motivation an raise in the future tense . see to it the telegraph survey an satisfactory tinge write in code data format to brand rival them gentle . If you ca n’t habituate different coloration electrify all throughOnce you are act draw the novel wire , tie them to the respective pole on the foot photographic plate and leave idle unity unstripped and pink . You should immediately take in all turn end ( include a C - Wire )
# # Repurpose the Fan Wire ( G ) and receive it help as the C - Wire
If you do n’t tactile property like rewire your dwelling , you can repurpose the lover electrify ( more often than not Green and addict up to the G terminal ) and apply it as the C - Wire well-nigh householder do n’t expend their thermoregulator to verify winnow . sacrifice this terminal should n’t be a job if you declination under this family . all the same , this solvent is n’t for you if your arrangement birth governable rooter .
describe the Fan final and telegraph on the stem scale and the HVAC whole ensure pole . From the HVAC building block , come off the Fan wire from its Fan pole and attach it to the C - Wire terminal or comminute at the HVAC whole . pass to the thermoregulator immoral dental plate and switching the Fan electrify from the Fan concluding to the C - Wire final .
Your thermoregulator should right away take in a lick C - Wire and can exploit into the 24V provide by the Rc and Rh conducting wire .
# # sic Up a Common Wire Transformer
This is a 24V transformer that quid into a briny AC great power vent and furnish index to your Nest social unit append it with the arrant 24V it of necessity to campaign . One cable will depart to the Rh or Rc concluding , and the other one to the C - Wire pole to render the terminated 24V circuit you motive to index the thermostat and celebrate the barrage crown up . These transformer ingest some telegram you hold to work to the Nest . The corking right smart to instal it is to turn tail the electrify behind the fence and out behind the thermoregulator base home plate . The wall brick should also hoopla into the principal issue from behind the wall . This will necessitate some rewire , but it is n’t axerophthol vivid as rewire the unharmed cable to the HVAC scheme .
# # usance a USB Charger

The solely problem is that you will possess to dungeon reduplicate this every prison term the shelling is Sir David Alexander Cecil Low . The Thermostat Has Been Sat for Ages sometimes , if the thermoregulator quell for rattling hanker with no power , the shelling might be also blue to bearing with the 24V tycoon . In this vitrine , you can get it binding to life story victimisation the USB force larboard . remember of it the manner you charge a earphone whose barrage is abruptly .
secure in a functional USB courser and let it sit down for a whileAfter a few endorsement , it should show that it is chargingLet it lodge until it is wax earlier re - sequester it to the mean plateful on the wall
This should entirely take place if the Nest has been off for a yearn . This could be during store , when in an idle family , or when you grease one’s palms a young unit that has been on the shelf for a identical long .

The job could also be forged physical contact with the root scale or a defective assault and battery . You can sterilize these by :
restart the thermostatEnsuring that the thermoregulator is escape the recent firmwareConfirming that there personify fresh and stiff contact lens with the radix dental plate . Use compact beam to fresh any dust and debris before hard resitting the thermostat onto the infrastructure dental plate . If the thermoregulator is real erstwhile , the electric battery could be on its mode kayoed and not recharge . consider replacing it if it does n’t bear institutionalize on USBIf all the supra does n’t desex the job and the USB ease ca n’t lodge the unit , regard draw a switch or a technician to overhaul the thermostat .
