EWC-St-2D
I had have the EWC control panel and the Zone 1 Honeywell thermostat died. I purchased a Honeywell RTH7500. Will this thermostat work with it? If so, how is it wired to work correctly?

Unfortunately that RTH7500 thermostat will not work for you on Zone One.
Your Zone One thermostat needs to have a separate O and separate B terminal.
The RTH7500 does not meet those requirements.
If you want a simple non-programmable thermostat you can use the Honeywell TH3110D.
If you would like a programmable thermostat you can go with the Honeywell TH4110D.
Both the O and B terminals need to be wired to the board separately.
