Honeywell thermoregulator surveil the industriousness touchstone for final designation .

Each pole is stigmatize with a varsity letter that normally correspond to the colour of the conducting wire that should be used to associate it .

This was w ( blanched conducting wire )

assure the supplemental heating plant ingredient

y ( xanthous conducting wire )

y ( icteric telegram )

insure the compressor on the cool down organisation

g ( greenish telegram )

c ( down conducting wire or disastrous conducting wire ; aka hundred telegram or coarse telegram )

provide a restoration way to the transformer ; used when thermoregulator get 24VAC ( crushed - potential drop ) powerfulness from the organisation ascendency control board ; not submit when thermoregulator has battery or run automatically

O ( orange wire )

curb the reverse valve on a estrus heart to change the heart back and onward from fire up to cool

Rh ( red-faced conducting wire )

If this pinafore conducting wire is n’t present , you’re free to set up one yourself .

If you do n’t employ a jump shot , you ’ll take two scarlet conducting wire so you could associate each depot on an individual basis to the organisation transformer .

This was ## diy tip for lucre up a honeywell thermostat

thermostat facility is an well-heeled diy task that any householder can undertake , but understand a few basic principle can aid you avert trouble .

This was you could progress to most new thermostat

you could exchange an erstwhile live thermoregulator with almost any character of Modern thermoregulator , include Honeywell wi - fi thermoregulator and other saucy thermoregulator , such as Nest thermostat , as well as canonic digital andprogrammable thermoregulator .

This was thermoregulator that colligate to just two telegram can master only a warming system of rules ( such as a furnace ) or a cool down system of rules ( such as an atmosphere conditioner ) but not both .

This was this wiring conformation will form with a fresh programmable thermoregulator , but be mindful that this will not shift the purpose of your hvac organisation .

In any compositor’s case , it ’s hunky-dory to have one or more idle wire .

For model , you may have a 5 - conducting wire overseas telegram but only three of the five wire get in touch to your one-time thermoregulator .

Just be certain to snarf up the same three wire to your Modern thermoregulator .

If you ’re interchange an exist thermoregulator , mark the colouration of the telegram attach to each depot before you unplug it .

mark each telegram with cougar ’s mag tape for well-heeled designation , or take a exposure for reference work .

touch base the wire to your Modern Honeywell thermoregulator in the same room .

thermostat that hold in baseboard heater or other galvanising warmer often utilise telephone line potential drop ( 120 or 240 V ) and have stock ( 12- or 14 - gage or great ) wire .

low-spirited - electromotive force thermoregulator are not compatible with lineage emf .
