Honeywell Lyric T5 thermostat install blowing hot air

I have installed the Honeywell Lyric T5 thermostat and everything seemed to be working except its blowing hot air when its set to cool. Not what you want during the summer, not quite sure what I am doing wrong. I have attached a pic of the previous thermostat set up and the new one, can anyone suggest what I am doing wrong?

1st - The white wire needs to go to W2/Aux as you have a heat pump.
2nd - You need to tell Lyric that you have a heat pump instead of conventional. Option 200 on page 20 -
