Chronotherm Iii Thermostat Questions - Honeywell T8624 Owner's Manual

CHRONOTHERM III THERMOSTAT QUESTIONS

1. The temperature displayed on
the Chronotherm III Thermo-
stat doesn't always match the
room temperature on another
thermostat located right next
to it. Why?
2. Can I control when the
furnace comes on in the
morning?
3. What does the HOLD key do?
First, the Chronotherm III Thermostat is a very accurate instrument designed to
sense both air temperature and wall temperature, like your body does. It gives
an average reading over a period of time. Second, it is self-adjusting, and will
take a few days after installation to adapt to your home.
With Adaptive Intelligent Recovery™, the thermostat will turn on the furnace as
early as necessary to reach your desired comfort temperature at the pro-
grammed time. The earliest it will be is 24 minutes per degree setback ahead of
your WAKE time, but it will vary depending on your system, the weather and
how much the temperature dropped in your house during the night.
If it is so cold outside that your house drops to your sleep temperature, the
furnace will turn on and off at night to control the temperature at that setting.
It bypasses all program settings and holds the temperature at the present
setting. To increase or decrease the temperature while on HOLD, use the
WARMER-COOLER keys. Touching RUN PROGRAM will return the
device to programmed operations.
