 |  "Honeywell T8411R to Tempstar"
, posted Wed 23 Apr 10:53  
I friend of mine that works with HVAC gave me a Honeywell T8411R and wired it up to my Tempstar Unit. He had difficulty getting it to work right but eventually got it...we thought.
Come to find out it was only using emergency heat, not the heat pump. I spoke with another HVAC guy and he walked me through what I need to do (put in two jumper wires).
That done, the heat pump fired up and worked great.
First warm day this Spring, I go to fire up the A/C (which worked before) and it starts blowing hot air.
I honestly think its something not right with the wiring.
Here's how it's currently wired.
Green wire to G
Blue wire to C
Red wire to R
White wire to W1
Yellow wire to Y
Orange wire to O
Jumper wire between W1 & Y
Jumper wire between E & W2
Black and Brown wire not being used.
I would appreciate any help with how this need to be properly wired.

When white was wired to W1 and W1 was jumpered to Y1, you would run the electric heat strips with cooling and heating demand.
This should be easily corrected by moving the white wire to W2.

Sounds like the reversing valve needs power, try changing the puting the orange wire on the B termanal of the t-stat
or your reversing valve is stuck and needs replaced
good luck

I think it's something else, do you have a meter?

Move white to W2 and leave W1 jumped to Y.
R = red
W2 & E = white (use jumper)
O = orange
Y & W1 = yellow (use jumper)
G = green
C = blue
