PREPARING THE UNIT
1. The WIN100 comes with (2) G13A size 1.5V Alkaline
Button Cell Batteries already installed. These batteries
power the clock only during normal operation. They also
provide backup power to retain the thermostats
programs and settings while it is not plugged into the
wall. In order to "activate" them, you must remove the
black ribbon from between the two batteries prior to
using it. Use a small regular screwdriver to pry open the
battery holder and pull out the black ribbon.

TEMPERATURE VARIATION / SWING
Your thermostat works by turning your heating or
cooling system on and off whenever the room
temperature varies a certain number of degrees from
the set-point temperature. This variation is the
"swing". Your system should cycle on about 3 to 6
times per hour. A smaller swing number increases the
number of cycles, so room temperature is more
constant. A larger swing number decreases the
number of cycles, saving energy in most cases.
This setting controls when the heating or cooling
turns on and off.
The Swing setting sets the temperature variation the
system allows above or below the set temperature
before turning on the heating or Cooling. To change
1. Rotate the SPEED DIAL
2. Press NEXT and HOLD simultaneously. The
Temperature section of the display shows a single digit
number between 1 and 9.
The WIN100 comes with (2) G13A size 1.5V Alkaline
Button Cell Batteries. During normal use, these
batteries are used for the clock only. However, they
also serve as backup power to retain your programs
and settings if you unplug it from the wall. These (2)
batteries will need to be changed once every year. The
thermostat will alert you when the batteries are low by
displaying "LO BATT" in the display.
1. Remove fresh batteries from their carton.
2. Remove the thermostat from the electrical outlet.
3. Use a small regular screwdriver to remove the
battery cartridge from the back of the thermostat. Use
the small regular screwdriver to remove the 2 batteries
