Programming a Honeywell Vision Pro Commercial Thermostat
Our small community library installed a Honeywell TB8220 Commercial VisionPRO Programmable Thermostat last summer and the installer programmed it with no coaching to the volunteers who try to keep the library going. He is extremely busy plus we are trying hard to avoid the $75 per hour charge. We have contacted Honeywell and they did send a more extensive owners manual. Is there anyone out there who can give an understandable overview of how to program and also how to understand exactly what the code numbers are?
