THERMOSTAT BUTTONS:
UP / DOWN = used for raising or lowering the target set
temperature and selecting user options and settings in
the display screen.
The temperature that is shown at all times in normal
operation is the Target Set Temperature.
To view current ambient room temperature while in
Heat or Cool mode, perform a single press of BOTH the
Up and Down buttons at the same time.
Note: to adjust the target set temperature, first ensure
that the thermostat is in either Heat or Cool mode, and
press either the up or down buttons until the desired
target temperature is reached. Presses to the Up or
Down buttons will have no effect when the thermostat is
in Off mode.
SETTING A KEYPAD / FRONT PANEL LOCKOUT:
• While in either HEAT or COOL mode, a keypad
lockout can be introduced which will prevent any
temperature adjustment from being made by
the user. Even while locked, any button press will
illuminate the display backlight.
• To activate (and deactivate) the keypad lockout,
press and hold BOTH the Up and Down buttons for
at least 5 seconds. When the keypad is locked, a
padlock will appear in the lower left corner of the
display.
