MOUNTING AND SET-UP
The controller is intended for indoor installation.
When installing the controller ensure unobstructed recirculation of air for cooling its internal elements.
Do not install the controller above heating equipment or in areas with insufficient air convection.
ATTENTION! After transporting or storing the product at sub-zero temperatures the controller must be kept
under the specied operating conditions for at least 4 hours prior to turning it on.
Inspect the product visually to confirm absence of any damage to the controller casing.
An automatic switch built into the stationary power supply network must be installed on the external input.
Note: To disable the ON / OFF function (3.0 A version only!) connect 230 VAC supply voltage to the unregulated output (L1).
In this case, do not connect the power supply unit to L.
DESIGN AND OPERATING PRINCIPLE
Controller casing is made of non-flammable thermoplastic.
The controller is equipped with an on/off button with backlight and an operation status indicator.
Output power change from 30 to 100% is made proportionally to the control signal 0...10 V or 4-20 mA in the selected range
during configuring the controller.
The control signal type 0...10 V or 4-20 mA is selected by a switch in the controller casing.
Controlling is possible with the use of a remote control panel, e.g. the R-1/010 controller.
The minimum rotation speed value is set by a variable resistor on the control circuit board inside the controller.
The controller has an additional terminal (230 V) for connecting and controlling external equipment (for example, air damper
drives).
The input circuit of the controller is protected from voltage and current overload by a fuse.

INSTALLATION INSTRUCTIONS
Find a flat surface for mounting (wall, panel, etc.).
Follow these steps:
1. Turn off the power.
2. Remove the front cover by removing the self-tapping screws and secure the controller to the wall or panel using screws
through holes located in the back wall of the device. Observe the correct mounting position and dimensions of the device.
(See Fig. 1: Mounting dimensions and Fig. 2: Mounting position.)

3. Connect the motor / fan. The connection is made using screw terminals on the controller circuit board.
4. Connect L1 output for three-wire connection, adjustable valve, etc. (if necessary). See Fig. 3.
