Post a picture of the connection diagram in your heatpump.

The Honeywell has theses pin outs
TH5110D
(Rc)=Linked to (r)
(r)=24vac power from heating
(y)=Compressor contactor
(c)=24vac Common (for 2 transformer systems use common wire from cooling transformer)
(w)=heat relay or (o) - (b)
(g)=Fan relay
(w) can be wired with (y) ?
York controler
(w)= white = heat relay
(r) = red = 24vac power from heating
(y) = yellow =Comp Contactor
(b) = Black 24vac Common
(o) = white (thick) Reversing
I am trying to answer my own questiions ...
Am i on the right track..? anyone able to let me know if this is correct? PLease
Thanks in advance

Your stat is not compatible with your multistage heatpump. You need separate O/B and W terminals. The TH5220 or 5320 will control your system. The 11 in TH5110 means 1 heat 1 cool.
Most modern Honeywell digital stats do not require a W to Y jumper.
Your common is black not blue, as in my diagram.
I always take several pictures in the hope that one isn't very blurry ;)

Thanks for that ,was scratching my head,havent had much to do with old york heat pumps, the old york units have different wiring colors as well?
TH5220
(Rc)=Linked to (r)
(r)=24vac power
(y)=Compressor contactor
(c)=24vac Common
(o)=reverse valve
(g)=Fan relay
(Aux)=Heat relay
York controler
(w)= white = heat relay
(r) = red = 24vac power
(y) = yellow =Comp Contactor
(b) = Black 24vac Common
(o) = white Reversing
So the set up would be on the TH5220
1 System Type:
Settings & Options
5 = 2 heat/1 cool heat pump
2 Changeover valve:
Settings & Options
0 = Changover valve o/b energised in cooling
3 Fan speed:
Settings & Options
1 = thermostat controls fan on heating
The other question i have is the fan wire(G)on the out door control board is Not conected anywhere? There is no place for it
i asume the Thermostat controls it?

The color combination at your outdoor unit will not help wire your stat as much as a picture of the wiring at the existing stat and the air handler. Both wire sets run to the air handler. The set using green is from the stat.
I suspect that a different wire color is in use for O at the stat.
