OPERATION RULES
The fan is rated for connection to single-phase AC 220-240 V / 50/60 Hz power mains.
The fan is designed for continuous operation always connected to power mains.
Air motion direction in the system must match the pointer on the fan casing.
Ingress protection rating IP X4.
The fan is rated for operation at the ambient temperature ranging from +1°C up to +45°C.
The transporting medium temperature must not exceed +60°C.

ELECTRONICS CONTROL LOGIC
The fan with the timer T is turned into operation after control voltage is supplied by the external switch
(e.g., by the light switch) to the input terminal LT. After the control voltage is off the fan continues to operate within the timer period set by the timer from 2 to 30 minutes.
To adjust there off-delay timer rotate the potentiometer control knob T clockwise to increase and counter-clockwise to decrease the off-delay time respectively (fig. 31).
Warning! The timer circuit is under mains voltage. All adjustments are allowed after disconnection from power mains. The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments. Use the screwdriver to alter the turn-off delay time or the humidity threshold.
Do not use a screwdriver, knife, etc. for adjustment operations not to damage the circuit board.
The fan model U(U1) (fig. 33) is equipped with electronic TSC module (speed controller with electronic thermostat) for automatic fan speed (air flow) control depending on air temperature.
The electrical compartment incorporates 2 control knobs: for setting the motor speed; for setting the electronic thermostat.
The fan cover incorporates a LED-light thermostat indicator.
To adjust the thermostat set point rotate the thermostat control knob clockwise to increase the set point and counter clockwise to decrease the thermostat set point. To adjust the fan speed (air flow) rotate the speed control knob in the same way.
The fan has two operating logics - temperature-based and timer-based operating logics.
temperature-based operating logic (U): RO
This logic is used to keep air temperature to within 2°C. In this case the fan switches are rare.
The motor sets to maximum speed as the temperature reaches the thermostat set point.
The fan runs with the speed set by the speed controller if the temperature drops 2°C below the set point or if the initial temperature us below the set point.
timer-based operating logic ( U1):
This logic is used for exact air temperature control. The motor changes its speed more often as compared to the temperature pattern, but one speed interval continues at least 5 minutes.
The motor sets to maximum speed as the temperature reaches the thermostat set point.
If the temperature drops below the set thermostat point, the motor sets to set by the speed controller speed 5 min. after the timer countdown. If the initial temperature is less, the motor starts operating at set speed immediately.
The fan (fig. 34) is equipped with a speed controller that enables switching the fan on/off, smooth speed (air flow) regulation from minimum to maximum value.
MOUNTING
The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling
(fig. 2) as one unit or included into connected in parallel or in series sets (fig. 3).
In case of the horizontal fan mounting install a straight air ducts segment on side of the intake vent not less than 1 m; in case of the vertical fan mounting install an outer hood to prevent water ingress inside the fan. The exhaust pipe must be connected to the air duct.
The mounting sequence is shown in fig. 4-12 and 25-30.
Wiring diagrams are shown in fig. 13-24.
