How do I set up the Honeywell thermostat with an economizer?

For the Prestige thermostat, go to settings and set ISU 2220: A/L-A Terminal Setup to Economizer. For the VisionPRO thermostat, set ISU 222 to Economizer. Both thermostats work with the Equipment Interface Module (EIM) to control the W7220 Jade economizer controller and coordinate damper positioning for energy savings.
