Automatic shutters/curtains control
The 666301 is a pre-programmed memory module that, in combination with one ElfaLogic CPU and one ElfaLogic
digital expansion module, controls up to 3 shutters. Future development will allow the control of up to 8 shutters
(One ElfaLogic and 3 digital expansion modules).
Manual control
• Individual control of each connected shutter/curtain
by means of pushbuttons:
o Brief impulse (

Application 3
Hotel room control
The 666303 is a pre-programmed memory module that, in combination with one ElfaLogic CPU and one ElfaLogic
digital expansion module, controls all electrical appliances in a hotel room.
All basic controls (for a basic room) are included in the CPU-module while additional appliances in bigger rooms
and/or suites can be controlled by adding the expansion module.

Application 4
Load shedding control (4 channel priority relay)
The 666305 is a pre-programmed memory module that, plugged in to an ElfaLogic CPU, controls up to 4 loads
according to a predefined priority-scheme (cascade) or in cyclic way.
A multi-channel priority relay is typically used to avoid the (main) MCB to trip due to excess load by shedding the
loads.
Cascade operation
At the start of each cycle (cycle-time is typically 7minutes
but user adjustable) the priority relay searches for the
optimal combination of switched-on loads, by switching
off the loads with the lowest priority first, until the measured
current drops below the threshold value (measured
i.e. by means of the 1-channel priority relay 666445).Once
the measured current has dropped below the threshold
value, the priority relay stops the sequence and the loads
currently switched on stay on until the next cycle starts.
The sequence executed is as follows (channel 1 highest
and channel 4 lowest priority)
Channel 1 2 3 4
ON ON ON ON
ON ON ON OFF
ON ON OFF ON
ON ON OFF OFF
ON OFF ON ON
ON OFF ON OFF
ON OFF OFF ON

1 channel priority relay CPU Memory module
Cyclic operation
To prevent from one or more channels to stay off systematically,
the other way of operating is for each load to
switch on for a certain amount of time and switch off
again while the next channel is switched on. A typical
application for a cyclic operation is electrical heating:
all electrical heaters switched on together would trip
the MCB, while in cascade set-up, the room with the
least priority could stay cold forever…
The sequence executed is as follows
Channel 1 2 3 4
ON OFF OFF OFF
OFF ON OFF OFF
OFF OFF ON OFF
