ANSWERING COMMON QUESTIONS ABOUT THE CHRONOTHERM III THERMOSTAT
9. Can I stop the thermostat from bringing the heat
on so early in the morning? How?
T8631A has screws on the back of the thermostat
that will allow you to turn off Adaptive Intelligent
Recovery™.
On the T8631R without the screw to override
Adaptive Intelligent Recovery™, you will only be able
to set one completely automatic energy savings
period; the second period must be ended manually.
Also, since recovery starts at the time you pro-
grammed, the comfort temperature may not be
reached by the desired time.
Do you have a heat pump with auxiliary heat?
If so, we don't recommend overriding Adaptive Intelli-
gent Recovery™ because the amount of expensive
auxiliary heat needed for recovery can cost more than
the energy saved by lowering the temperature.
EXAMPLE:
PERIOD TIME SETTING
WAKE 5:30 AM
LEAVE
SLEEP 10:00 PM
RETURN 5:20 AM
If you want a day program:
Set the desired LEAVE time and temperature. The
thermostat will automatically initiate an energy
savings period.

Here's how to override Adaptive Intelligent Recovery
setting:
Set the desired WAKE program temperature.
Set the WAKE program time 30 to 60 minutes before
the time you normally get up. (You can adjust this
time. If the house reaches the comfort temperature
too early, set the time later; if it reaches the comfort
temperature too late, set the time earlier, but don't go
beyond 90 minutes.)
Set the desired SLEEP program time and tempera-
ture. The SLEEP temperature must not be more than
10 degrees below the comfort setting.
Set the RETURN program time to 10 minutes before
your programmed WAKE time.
Set the RETURN program temperature the same as
the SLEEP temperature.
The LEAVE program remains blank unless you want
a day energy saving period. See page 3.
The thermostat will think that it doesn't need to start
recovery until 10 minutes before your WAKE time. It
will run the furnace constantly until the comfort
temperature is reached.
The first person home must push the CHANGE
TO LAST PERIOD key to start warming the
house. The furnace will run constantly until the
comfort temperature is reached.
10. I have a high efficiency furnace and my heat is
short cycling. What can I do?
Some high efficiency furnaces need the cycle rate set
at the Hot Water setting instead of the factory setting
of gas/oil warm air. Turn out the 1A screw with screw
1B left turned in.
