can be adjusted to modify the cycle time.
Press UP and DOWN buttons for 3 seconds.
SPAN will be displayed on the LCD.
Press UP to raise the span to 3. This setting increases to cycle time by allowing your system to
run longer.
Press DOWN to lower the span to 1. This setting decreases the cycle time by causing your
system to run shorter.
The span settings remain the same for both heat and cool, and can be changed in any system
switch position.
When batteries are installed in the controller, the span is reset back to setting 2.
8) Backlight
The wired controller has an electroluminescent lamp that backlights the display for easy viewing
in the dark. When any key is pressed, the display is illuminated.
The display will remain illuminated fo r 5 secon ds after the last key is pressed. This allows the
light to stay on if you need to operate several keys.
Notes: If the controller is in low battery warning condition, the backlight will not operate. Replace
with 1 new AA alkaline battery to restore the backlight function.
9) Changing the battery
One fresh AA alkaline battery should provide well about one year of service. However, when the
batteries become drained, the controller is shut down. At your earliest convenience, you need to
replace the battery with 1 new AA alkaline battery.
Notes: If you plan to be away from the premises over 30 days, we recommend that you replace
the old battery with new alkaline battery prior to leaving.
10) Auto turn-on
The controller will automatically cut off in heat mode if the room temperature rises above 95
˚F
(35
˚C). It will cut off in cool mode if the room temperature drops below 45˚F (7˚C).
Note that if your system has malfunctioned and no longer responds to controller controls, the
auto cut-off will have no effect.
