SMART RESPONSE™ TECHNOLOGY
Your CT3650 is actually a small computer. The Smart Response technology calculates the correct time of day to turn on your heating or cooling system. Smart Response technology considers the following information.
•Air temperature.
•Wall temperature.
•The time of day when you want the comfort temperature established.
When the thermostat activates Smart Response technology, the thermostat displays In Recovery, changes the setpoint, and turns on the system.
•Your CT3650 thermostat learns from experience. Each day it checks how closely it hit the recovery target and then adjusts the next day’s recovery start time accordingly.
•It takes a few days after installation for the thermostat to adjust to the local weather, your lifestyle, the construction of your home, and your heating/cooling system.
•You can turn off Smart Response technology by selecting Conventional Recovery. See Step 7. Customize Your Thermostat.
