Description of regulator
-
The regulator is used to continuously control the speed of the EC-motors with the control input 0-10VDC
without connection to the mains power supply.
-
The motor speed is controlled continuously by the control element (a knob) on the front panel of the
regulator.
-
For information on the operation of the connected equipment, the operating signal diode is located in
the upper part of the front panel.
-
The regulator is supplied with direct voltage of 10 VDC from the EC-motor. T
-
he regulator is designed for wall installation.

Description of connecting terminals
-
Spring terminals with manual locking are used to connect the wires. A strand-type conductor (cable)
and a solid conductor (wire) in the cross-section range from 0.5 to 1.5 mm² can be installed in the
terminals.
-
Before inserting the wire into the terminals, first press the locking orange button. Then slip in the wire,
release the lock and slightly pull it out of the terminal to verify that the wire is properly secured. If the
wire needs to be removed from the terminal, the procedure is the same.
-
The optimum cross-section of the conductor must be selected according to the actual length of the
conductor route; however, the cross-section of the conductor may be 1.5 mm

.
-
All wires shall be connected to terminals with adequate force to prevent damage to them or damage to
the electrical board. Stripping of cables to individual conductors should be 10mm. In the case of strand-
type conductors, an end piece must be pressed on (tube).
Signalling diode
– signals the operation of the entire
regulator. If the diode is lit, the regulator is active. If
the regulator is not on, it is switched off.
Continuous fan speed regulator
– allows smooth fan
speed setting in any position from minimum to
maximum fan speed as required by the user. The
"OFF" position allows the entire regulator to be
switched off. The "OFF" position does not provide
disconnection of the controlled equipment from the
supply voltage – it must be performed separately on
the supply
