Is my Honeywell rth3100c thermostat wiring hooked up correctly?
Jan 11, 2008 by lostdope | Posted in Do It Yourself (DIY)
The wires on the thermostat are hooked up as such.
Six wires
(white) to Aux jumpered to E
(yellow) to Y
(green) to G
(red) to R
(blue) to B
(brown) to C
O and L are left unwired
Everything
You didn't give enough information but I can tell you the industry standard.
white = heat
Green = fan
red = 24V power
Brown = common
Orange = usually reversing valve
Yellow = cooling
