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.
