Fig. 25. LED location on W7761A.

T7780 DDWM Bypass Pushbutton

See Fig. 26 for the T7780 DDWM bypass pushbutton location (occupied or unoccupied). The T7780 DDWM has two methods for generating its neuron ID, shorting two pads or winking.

1.Pressing the bypass pushbutton whenever a Carat (∇) on the bottom of the LCD display is flashing (Menu Selection Mode).

2.Pressing the bypass pushbutton when the T7780A DDWM is in wink mode (LCD display shows WINK when E-Vision sends a Service Message out on the E-Bus).

When the space covered by the T7780 DDWM is in Occupied mode, the sun symbol is shown on the left side of the LCD display. When the space is in Standby mode, the half-sun symbol is shown. When the space is in Unoccupied mode, the moon symbol is shown.
