KOMFORT EC L S6
The unit is rated for connection to single-phase alternating current power
mains 230 V / 50/60 Hz.
The unit is connected to power supply via a pre-wired power cable with a
plug. In case of need to connect a longer cable follow the wiring diagram
below. The electric connections must be performed with insulated, durable
and heat-resistant conductors (cables, wires) with a matching cross section.
While selecting the conductors with respective cross section consider the
wire type, the maximum permissible conductor heating temperature, its
insulation, length and layout.
Use copper wires only!
The unit must be grounded in compliance with the valid electrical standards
of the user country!
The fixed electrical wiring must be equipped with an automatic switch that
is used for connection of the unit to power mains with a gap on all poles at
least 3 mm. The automatic switch trip current must be not below the rated
current consumption.
The recommended rated automatic switch trip current is 2 A. The
Recommended cable cross section is 0.75 mm

The unit has extra electric connection options. Designation of the contacts on
the sticker of the X3 terminal block are enclosed in brackets, fig. 8:
•
PK contact for connection of the fire alarm panel.
While connecting the automatic fire alarm system remove the jumper
between the terminals 1 and 2. In case of fire a normally closed dry contact
opens the control circuit from the central fire alarm panel.
•
H contact for connection of the humidity sensor or CO
2
sensor.
The humidity sensor or CO
2
sensor is connected to the terminals 3 and 4. If
the sensor is activated, the normally opened dry contact is closed and the
unit switches to maximum speed.
•
Y-N, Y-L, Y-C contact for connection of the three-point control damper.
The air damper actuator is connected to the terminals 5, 6, 7. One more air
damper may be connected to the same terminals.
Connect extra contacts according to the electric wiring diagram, fig. 8.
