Thermostat set up

I am switching thermostats from a smart control 2311 to a lyric T5. The house is 2 zones with a master and slave thermostat. I have changed the master thermostat out, but it seems to be short cycling now (it kicked on 3 times in 20 Minutes this morning). Here is where all the wires go:

Old setup:

r-red
C-blue
W1-orange
Y-yellow
E-white with a jumper to W2
G-green

Current
A/b-orange
Y-yellow
G-green
C-blue
W-white
R-red

Slave setup (thermostat has not been changed)

R-red
C-blue
W1-white
Y-yellow

Does this wiring look correct? I did not notice it kicking on that often before the switch. Thanks
