T-Stat Wiring - Lux TX9100e replaces Honeywell T8411R for Carrier Heat Pump/Cooling

I’m trying to replace my girlfriend’s old thermostat with a new programmable thermostat. I did this last night, but I couldn’t get the AC to come on… I’m hoping someone will see my error.

Many thanks,

Carrier: Heat Pump with Cooling
Model # FA4BNF018
Product FA4BNF018 010 AAAA
Heat Pack MKFCEH0901N10

Old t-stat
Honeywell T84 11R 1002
(This was wired with 8-wire as listed below.)

G = green
C = charcoal
R = red
W1 (jumper to Y) (no wire)
Y = (jumper to W1) yellow
W2 (2 wires) = white; light blue
E = black
B (No wire)
O - orange

New Tstat
Lux TX9100e

A (No wire)
RH jumper to RC
W2 (former w2 wires) = white; light blue; Black
RC = red
G = green
Y (Jumper W1) = Y
W1 (jumper to Y) (No wire)
O - O wire
B (No wire)
C = charcoal

Today I will also check the 3amp fuse in the blower.

Any suggestions would be great.

Get your voltmeter and measure the following when the thermostat is calling for AC:

Y to C

R to C

C to G

Personally, I'd never substitute Lux for Honeywell.
