Color codes vary, remove power to your fancoil and write down your existing color codes before removing any wires.

You must also configure thr RTH7400 to match your system.
Option 170 = 7
190 = 0

"Tip of the Day" Remember to remove power first.

my existing Carrier's non-programable thermostat (TSTATCCNHP01-B) has been wired in the following terminals (in exact order):

O/W2

R
Y/Y2
G
C
W/W1

How do I map them to the terminals in RTH 7400D?
