One of the main features is the function SOFT‐START that allows the product to
start the rotation with an
acceleration ramp and then reach the speed of rotation proportional to the temperature. SOFT START function

An intelligent management of the electric fan speed allows for a smoother and more gradual trend of the
temperatureinthesystemtoavoidunnecessaryheatstress.
Among the various options of the ESC it is to
report the possibility to manage the Reverse of rotation of the
electric fan and in so doing to keep clean the surface of the radiator, this function is particularly useful for all

VersionsavailableofESC:
ESC–SR=ElectronicSpeedControlwithStandard
Rotation
ESC–RR1= Electronic SpeedControl withReverse Rotation type_1‐The reverserotationstarts only when the
electricfanstopstherotationaccordingtothetemperatureset
ESC–RR2 = Electronic Speed Control with Reverse Rotation type_2‐The reverse rotation starts automatically
(even if the temperature is still high)
with a cycle time set in the software of the electr onic speed control.
Example:10min.inStandardRotation+30sec.inReverseRotation.
Please Note: In order to avoid damage to the mechanical parts in motion, for each Reverse Cycle are planned
ramps of deceleration and acceleration and
at each change of direction of rotation of the blade is expected a
periodofcompletestopoftheblade.
2.GENERALWARNINGS
The ESC is a component source of risks mainly of electrical origin, therefore, if used improperly, it can create
dangerousconditionsandcauseharmtopeople,animalsandthings.
Please read carefully the following instructions before its connection; each operation of installation and
commissioning,shouldbeperformedbyqualifiedpersonnel
incompliancewithallapplicablelaws.
