Controller Operation
The controller automatically adjusts lighting levels from received input from the
following wireless devices:
• ambient light levels monitored by a wireless photo sensor
• occupancy state monitored by a wireless occupancy sensor
• switch action from a wireless wall switch
• gateway control implementing scheduled or other events
Controller and Wall Switches
Echoflex switches can also be used as dimmer switches – press and hold the ON or OFF
side of a linked switch to modulate the dimming output up or down.
The controller works with the wireless single and dual rocker switches. A switch ON
action will ramp the dimming output to the last dimmed level set by a switch. If a photo
sensor is linked to the controller as well, the output ramps to full output over 2 seconds.
A quick double-press ON will ramp up to maximum output and accelerate the fade
period to ½ second. A press OFF action will fade the lights down over 2 seconds. A quick
double-press OFF will accelerate the fade period to ½ second.
Controller and Timed Switches
The controller can be configured so the single and dual rocker switches become timed
switches. An ON action turns the lights ON and a timer is set to count down. Once the
timer expires, the lights fade to OFF.
The time period is configurable and has 5 settings: no timer (default), 5 minutes, 15
minutes, 30 minutes and 1 hour. Additionally, if the user presses the rocker switch ON
multiple times ( to a total of 5 presses), the timer interval is added for each ON press.
If ON is pressed while the lights are on and the timer is counting down, an additional
period of time is added to the timer total.
Example: if the timer setting is 1 hour and the user presses the switch ON twice, the
total timer period is 2 hours. If there is 30 minutes left on the timer and ON is pressed
again, the timer is extended to 1 hour 30 minutes before the lights will turn off.
The controller will ramp the light output down then up (flick-warn) 1 minute before the
timer is due to expire to warn users of the pending OFF event.
To configure the time period, refer to the section on ”Configuring the Controller”.
Occupancy Based Lighting Applications
The controller will turn the lights OFF when there is no motion detected in the room
indicated by a linked motion sensor. If the application requires the lights to remain ON
during vacant periods but at a dimmed level (i.e. warehouse or stairwell applications), a
configuration property accessible using Garibaldi software can enable this feature.
Occupancy sensors only: When only occupancy sensors are linked to the controller, the
sensor will automate the lights both ON and OFF.
Occupancy sensors with switches: When switches and sensors are linked, the controller
will assume manual-ON, auto-OFF operation referred to as Vacancy Sensor Mode.
The controller can also be configured to turn the lights ON immediately (Auto-ON) with
motion, see the section titled “Configuring the Controller”.
Photo Inhibit: This feature requires a linked photo sensor. When Photo Inhibit is enabled,
the Auto-ON feature will be ignored when the natural light level measured by the light
sensor is above the day-lighting set point. The photo inhibit feature will not turn lights
OFF if the lights are ON.
