EKEY HOME CP DRM 1 (2)

CONTROLS
The ekey home CP DRM has 4 buttons and an LCD display for system operation and programming. It also
features a sliding switch to switch on and off the bus termination, as well as 1 respectively 2 LEDs for
relay status and digital input signaling.
The ekey home CP DRM is optimized for its electric consumption. For this reason, the LCD display
is deactivated automatically after approx. 2 minutes. This way, the energy consumption is reduced
significantly. To make any system changes, please press any key to reactivate the display.
Signaling of the relay and input state
The ekey home CP DRM features one respectively two status LEDs monitoring
the relay switching status. This LED is implemented in green color. The LED is illuminated when the
relay output is switched actively, i.e. contact NO = closed
the status of the digital input. This LED is implemented in red color and illuminated when the
electric resistance between the input pins is smaller 1kΩ ist (= external push button is closed). The
LED is for sure not illuminated if the resistance is >50kΩ (push button open).
