Honeywell Programmable Thermostat, Owner'S Manual

1. Why do some models of this
thermostat have lights? Battery-operated thermostats do not have indicator lights to conserve
battery power. Others may have one or two indicator lights, depending
upon the exact model and application.
2. The temperature displayed on
the thermostat doesn’t always
match the room temperature on
another thermostat located right
next to it. Why? First, the thermostat is a very accurate instrument designed to sense
both air temperature and wall temperature, much as 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.
3. Can I control when the furnace
comes on in the morning? When the thermostat is set for Programmed Recovery, it will turn on the
furnace as early as necessary to reach your desired comfort tempera-
ture at the programmed time. The earliest it will be is 43 minutes per
Celsius 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 at night.
If you want to control the start time yourself, just switch the thermostat
to conventional recovery following the directions on page 6. This way,
the furnace won’t come on until your programmed WAKE time, but of
course it will take a little while for your house to heat up to the comfort
temperature.
