Step 1. Set Current Time and Day
Step 2. Learn About Programming Features
Your 3200 Thermostat allows you to program schedules for both a heating season and a cooling season. 
• During the heating season, you will want to set the normal room temperature higher and the energy-saving 
temperature lower. 
• The reverse is true during the cooling season—the normal room temperature will be lower and the energy-saving 
temperature higher. 
For each season, you can set up to four program periods...
