MOUNTING AND SETUP

WARNING

After transportation or storage of the product at temperatures below zero keep the product at rated operating temperatures at least 2 hours.

The speed controller is designed for indoor application and vertical mounting inside a junction box.

Perform visual inspection of the product and check possible casing damages if required.

Wall flush mounting (IP44)

For connection of the speed controller to power mains:

•

Cut off power supply

•

Remove the control knob.

Detach the fastenings and remove the cover.

•

Remove the fasteners that fix the controller to the junction box and remove the speed controller.

•

Route the connecting wires to the junction box.

•

Connect the speed controller following the wiring diagram. Connect the external wires to the product with screw terminals.

•

Mount the speed controller inside the junction box in such a way that the terminal block is located downwards.

•

Install the junction box inside the wall with the connection terminals downwards.

•

Provide power supply and turn the speed controller on.

Adjust the minimum fan speed in the end position of the control knob.

•

Turn the speed controller off.

Turn the speed controller on at minimum speed and make sure the fan has smooth running at minimum speed.

•

Put the cover.

BASIC CHARACTERISTICS AND OPERATING LOGIC

status.

The product has:

- regulated output terminal connected to the fan motor;

- regulated output terminal connected to the fan motor;

- block of thermal fuses of quick response type, made of ceramics.

The speed controller casing is made of plastic.

The speed controller has a control knob with light indication of the controller operating

To turn the controller on press the control knob. Speed control is regulated from minimum rotation speed that ensures stable smooth running up to the maximum value. The minimum speed value is set by a variable trimming resistor on the speed controller circuit board.

Several fans may be controlled by one speed controller if their total current does not exceed the maximum permissible controller current.

The speed controller is equipped with extra terminal (230 V) for connection and control of external equipment.

The speed controller is equipped with a thermal fuse in compliance with the controller type (refer to the table) to prevent excessive overcurrent.

The speed controller is equipped with a transient filter.

- Connect the speed controller to power mains through the automatic circuit breaker.

•

Install the control knob.

Rotate the control knob to position off.

The system is operable.

Wall surface mounting (IP54)

To connect the speed controller to power mains:

•

Cut off power supply.

•

Fix the casing to the wall, route and fix the cables.

Remove the control knob.

•

Remove the fasteners and cover.

•

Route the connecting cables to the mounting box.

•

Connect the speed controller according to wiring diagram.

Connect the external wires to the product with screw terminals.

•

Fix the internal part of the speed controller inside the junction box with screws.

Provide power supply and turn the speed controller on.

•

Adjust the minimum fan speed in the end position of the control knob.

Turn the speed controller off.

•

Turn the speed controller on at minimum speed and make sure the fan has smooth running at minimum speed.

•

Put the cover.

•

Install the control knob.

•

Rotate the control knob to position off.

Drill 5 mm hole to enable condensate drainage in case of wall surface mounting if required.

The system is operable.

WARNING! The speed control range is limited by the fan operating features.

SAFETY PRECAUTIONS AND WARNINGS

The speed control range is limited by the fan motor electric parameters.

The fan motor must be Triac controllable.

Consider the fan electric parameters while decreasing the fan speed.

All the controlled speed range must be within the operating range to prevent possible malfunc

tion of the fan.

The speed controller and connected to it equipment are the sources of electric shock hazard.

Only qualified and trained electricians are allowed for its connection and operation.

The speed controller is related to electric equipment up to 1000 V.

Disconnect the product from power mains prior to all operations requiring access to its internals.

The speed controller is compatible only with single-phase motors.

The total current consumption of the electric devices connected to the product must not exceed the maximum current of the speed controller, refer technical data.

Avoid operating of the product with maximum load current.

Handle the speed controller with care. Do not hit it, avoid overloads, liquid and dirt exposure.

In case of foreign object ingress on the circuit board disconnect the speed controller from power

mains and withdraw the foreign objects.
