Just bought the RTH7600 to replace my manual thermostat and have a question regarding the wiring.
The line being run up the thermostat contains 6 wires: red, white, green, blue, orange and black
Thermostat (main floor):
Manual thermostat - red and white.
Humidifier control - green and blue.
Not used - orange and black.
Furnace (basement):
R - Red
C - Green
W - White wire and blue wire
Y - (empty)
G - Black
Since the orange is free on both ends, it's easy enough to make that why if needed.
As far as the green goes though, would I want to chain it from the humidifier control?
My system is a heat with fan (no A/C)
