BCP-3 Installation and Operation Manual
Button and Navigating Menus
The BCP-3 has three buttons.
• The SET button function varies. When the Default Screen is
displayed, pressing the SET Button views the MENU. When
in the Menus and settings, the SET Button accepts the selected
entry or setting value.
• When in the menus, pressing the Up and Down buttons will
scroll through the menu options. They can be used to change
the setting of a specific function. I.e., change the Set Point,
Differential, or System Trim. In addition, when in the default
screen, the Up and Down buttons will display the outdoor
temperature and Outdoor Cutoff.
• At the end of every operation menu there is a <Back> option
that allows the user to go back one menu level. If the SET
Button was held down for three seconds on the <Back>
option, the display will go back to the default screen.
