A four button arrangement is located on the front of the KWW.
These buttons are used in adjusting fan operation, changing
the set point temperature up or down and changing the
operating mode of the thermostat. *Note that the Up, Down,
and heat/Cool buttons are also used for setting the clock
and programming the thermostat.
Button Definitions:

Step 4: Mounting the Thermostat
Note: Mount the thermostat about five feet above the floor. Do not mount the thermostat on an
outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.
The KWW has six (6) mounting holes. Back plate will match up with existing electrical box or
drywall mounting ring.
1- Remove back plate from thermostat housing and use it to mark the mounting holes. Ensure
thermostat is level for aesthetic reasons as orientation will not affect operation.
2- Drill 3/8” holes and insert drywall fasteners (#6 Screws recommended) and fasten the back plate
to the wall.
Optional-
Located on the back of the housing is a built-in hinged stand support. This feature permits the
thermostat to stand on a flat surface such as a table or shelf, in the event that permanent mounting to a
wall is not desired.
Four buttons located on the left side of the thermostat (Figure 13) control
display of temperature in either Fahrenheit or Celsius, programming, clock
setup and control of whether the thermostat is under manual or program
control.
A single button on the right side of the thermostat activates the display
backlight. When pressed, the backlight will illuminate the display briefly
and turn off. If other buttons are pressed immediately after the backlight
button, the display will stay illuminated until a few seconds after all button
activity has ended. Backlighting takes significant energy from the batteries
and should be used sparingly. Frequent use of the backlight function will
noticeably reduce battery life.

RUN BUTTON- Program / Manual Operation:
The RUN button toggles the thermostat between manual operating mode
and program operating mode. When in the program mode your thermostat
responds to the times and temperatures programmed.
(Figure 14) shows a thermostat running in program mode. One of the four
periods, in this case “Day”, is displayed, letting you know which period of the
day the program is in. When in manual mode as shown in (Figure 15), the
period of the day is not displayed. Instead, the word “HOLD” will be
displayed above the set point temperature, indicating the thermostat is
holding that temperature.
Note: When “OFF” appears on the display of the KWW the system has
turned off based on the set point.
In manual mode you can adjust to the desired temperature using the UP
and DOWN buttons, and the thermostat will maintain that temperature until
you change it again.

You can always change the temperature up or down while a program is
running. However, when the program moves to the next period, the
programmed set point temperature for that period will take effect. For
instance, assume the current program period is Evening, with a
programmed temperature of 70°, and the next period, Night, is programmed
for 65°, scheduled to start at 11:00 PM. If during the evening time period
you desired the space to be warmer, you could press the UP button to raise
the temperature set point. The thermostat will hold that temperature until the
next program period, at which point the temperature will adjust to the
programmed temperature set point for that period. In this case the Night
period is set for 11:00 PM and 65°. (Fig16)
