C-BUS TRAINING MANUAL - VOL 2

1.1.3 One and Two Key Congurations

The single key On/Off conguration may be extended so that one key turns the load on and one turns

it off. This is done during Learn Mode by pressing two adjacent keys on a single Input Unit.

After exiting from Learn Mode, the rst key will turn the light on and when the second one is pressed

it will turn off. When the 'on' key is pressed, the indicators on both keys will light since they are both

associated with the same load. When the 'off' key is pressed, they will both go out.

Similarly, two key dimmer operation is used to separate up and down dimming operations. The rst

key will turn the load on (Short Press), or ramp the load upward when pressed and held (Long Press).

The second key will turn the light off (Short Press), or ramp downward if pressed and held (Long

Press).

If two keys are pressed on a particular input unit during the Learn operation, the last two keys pressed

will become the 'On/Up' and 'Off/Down' keys respectively.

1.1.4 Area Address Switching

Area Address switching functions are commonly required, giving the ability to provide a Master On/Off

switch that turns all lights and loads on or off simultaneously. This special case occurs when all Output

channels on all Output Units are selected, and then one of those Output Units is used to exit Learn

Mode.

It is assumed that the primary function of the key is intended to be as a Master Off switch. Hence

a Short Press of the key will instantaneously turn off all selected lights and loads. A Long Press on the

key will turn them all on.

Two Key Master switch congurations are permitted, with the rst key assigned the Master On

function, and the second key a Master Off function.

Master Switching controls should be congured last using Learn Mode.

To implement Area Address Switching:

• Set the Network into Learn Mode

• Turn on all Local Toggle buttons

• Select a C-Bus key to control the Area Address

• Exit Learn Mode.

You can still individually control each load for any Unit which has Master Switching implemented. The

individual loads must be learned rst, then the Master Switch congured.

Some temporary indicator state mis-matches may occur when Units are operated in this way;

however these are normally resolved automatically in seconds.

1.1.5 Timer Congurations

The C-Bus2 system offers many timer options and some of these are available by means of Learn

Mode. To create a timer switch once in Learn Mode, press and hold the key on an Input Unit.

The key indicator will come on after 1 second and then a series of double ashes will occur. Each

double ash represents a time period of 5 minutes, with your selection being made when you release
