OPERATING YOUR THERMOSTAT
Backlight Operation
When any button is pressed, the backlighting will
illuminate. Once the backlight is on, subsequent button
presses will perform their respective tasks.
Using the Up & Down Buttons and Multi-Function
Buttons on the Thermostat
This thermostat uses a menu driven display and four (4)
buttons. The Up and Down buttons are generally used
to move between selections in the menu and to raise
and lower different parameters such as temperature,
days, minutes etc., depending on which screen you are
viewing. The multi-function buttons have a variety of
uses. The portion of screen directly above these
buttons will display the button’s function. For instance,
when the main screen is being viewed, the buttons are
titled INFO and MENU from left to right respectively.
To access the menu of the thermostat, press the right
multi-function button.
Notes on Temperature Adjustments
The Cool setting must always be 2° or 5° (F or C)
higher than the Heat setting. The value (2° or 5°) is
selectable. The thermostat will automatically change
the temperature setting not being adjusted to maintain
this difference, even if both settings are not shown on
the display.
