Unfortunately this will not work for your model number. The control boxes and thermostats compatible with your unit are now obsolete. A transition to the new 9000 zone control setup is necessary. You will need Thermostat 9330A3341 and one of the following control boxes: 9430A751 for cool only, 9430A755 for cool with heat strip option, or 9630A751 for heat pump with heat strip option. I've included a link to the instructions for upgrading from the 8000 zone control to the 9000 series for your review.
