Button / Screen GCL Programming

GCL is used to program the thermostat user experience. The display and button
interactions are configured primarily by reading button presses from the
LCD0.Keypress property and writing to various display properties of the LCD object.
Reading and writing to database objects can adjust additional display
characteristics such as color or brightness and also provides a way to simplify slider
interaction.
For example, you might want to control a fan speed by having a user press the fan
icon. You would program the thermostat to recognize a fan button press, display the
current fan speed and then allow the – or + slider icons below the display to adjust a
value.

Button Mapping

This topic covers button layout and configuration plus using GCL with buttons and
the slider.

Button Layout

The standard thermostat has 4 buttons above the LCD, 4 buttons below the LCD and
a horizontal slider below that. Buttons on the thermostat can combine to form a
single button. The top and bottom rows of buttons could be 4 separate buttons, 2
separate buttons (divided between the second and third), 3 separate buttons
(divided between 1st and 2nd, 3rd and 4th) or one large button. The button layout is
factory set to match the overlay; however it can be modified through the onscreen
Configuration Menu if a different combination is needed for testing.

Button Config

The button layout configuration is in the CFg menu. Mappings are made for each
button to map the physical touch area to a logical button:
