Please Help - Thermostat Confusion

thermo HELP.pdf

I am trying to install a new thermostat (Honeywell RTH9585WF).
The new thermo is meant to replace two existing thermostats (both Honeywell RTH230B). One thermostat goes to heating / boiler and the other thermostat does to cooling / central AC.
After quite a bit of stumbling along, I cannot figure out how to wire the two existing thermostats into the new thermostat.
Attached is picture/diagram of all my wires.

Thanks a ton if you can help!!!!
