-  LOAD MANAGEMENT mode

This mode, only available if Local Display is configured using the software, gives the 
possibility of displaying loads, with their priority levels, and force their activation. The 
device can manage up to 20 loads; if these are connected to actuators with current 
sensor it will be possible to display other load information, like the instantaneous power 
consumption. 
When the central unit for load management intervenes on a load, the device (if enabled 
during the configuration) notifies the event with an indication on the display and an 
audible notification. 

Functions

After the configuration of the device it will be possible to select the various loads using 
icon 1.
Icon 4 is disabled until the moment the central unit disables the load; when this 
happens, the icon becomes active, and can be selected to force the activation of the load. 
In this condition, icon 3, used to intervene on the status of the load, is disabled. 
However, if icon 4 is disabled, it will be possible to select icon 3 to pre-force the load, 
and avoid disconnection in case of intervention of the central unit when consumptions 
are exceeded.
If the loads are connected to actuators with current sensor, use icon 2 to access a 
submenu that can be used to display the instantaneous power consumption, as well as 
information form the line total consumption meters. While in this submenu, you can use 
the RESET icon to reset the meters. Press key 2 for 3 seconds to access the menu used for 
setting the time, the date, and the sound notification (beep).

-  Advanced CEN SCENARIO mode

For systems with MH200N scenario programmers, Local Display can be used to enable 1 
of the 4 scenarios displayed. This is done using the associated icons. 
This function is only available if Local Display has been configured using the software.
