USES

The Dalap NOMIA household axial fan is intended for use in small and medium-sized residential and non-residential units.

The fans may be used for continuous ventilation.

SAFETY REQUIREMENTS

Please read this manual carefully and pay attention to all the requirements before use.

It is prohibited to install the fan into ducting systems that are used to conduct ﬂue gases away.
The installation, connection, and maintenance of the fan may only be done when the fan is disconnected from the mains.

The timer and humidistat may only be set after the fan has been disconnected from the mains.
Both connection to and disconnection from the supply network should only be done by a specialist electrician.

This device is not intended for use by persons (including children) with reduced physical, sensory, or mental abilities or r lack of experience and knowledge, if they are not supervised or the person responsible for their safety has not provided them with the instructions for use.
The fan is designed for connection to a single-phase alternating current of 220–240 V with a frequency of 50 Hz.

The degree of protection is IP25. Operating temperature from +1 to +40 °C.

MAINTENANCE

Only perform maintenance on the fan when disconnected from the mains! Conduct maintenance at least once a year. After removing the fan, clean it with a soft rag dampened with a mild solution of water and detergent. Be careful not to wet down the electrical parts of the fan, especially the motor. Wipe the fan dry and return it to its installed position.

TROUBLESHOOTING

Connection

Switch off ﬀthe electric circuit that you are going to work on.
Unscrew the screw on the front panel’s side and remove the cover under which the terminal block with two terminals is located.

Run the supply cables (permanent phase and neutral) through the rubber bushing and connect them in the terminal block. The positions of the cable connections do not matter in this case.
After completing the installation, connect the electric circuit and test the function of the fan.

CONTROL ELEMENTS

The fan is connected by three wires to terminals “L”, “TLH and
The timer is controlled by an external switch.
The fan is activated when the switch is turned on and runs as long as it is on.
When the external switch is turned off, the fan will run for the time set on the timer and automatically turn off.
The timer is set by the “TIME” potentiometer on the electronics:
- In the leftmost position, the timer is switched off
- In the rightmost position, the timer time is 30 minutes.
Use a small screwdriver to adjust.

WIRING DIAGRAM

The is connected with two wires to terminals and “L” (it is recommended to use polarity, so the board will work more efficiently and the fan operates in automatic mode.

MODES OF OPERATION

! The default setting at the factory is the typical automatic mode of operation.

The fan will turn on when the built-in humidity sensor detects humidity above 70% (SECTION 1) and will run until the humidity sensor detects a decrease to 70% or below (SECTION M). The fan will then run for 15 minutes (SECTION 2) and turn off. Every 12 hours (SECTION’) the fan will turn on and then turn off after 30 minutes. If the fan is installed in a room with permanently low or permanently high humidity levels, it is recommended to disable the built-in humidity sensor (SECTION 1). For convenience, it is possible to set the fan to turn on only when there are no people in the room (determined by the absence of lighting). To do this, turn the MODE switch to the “OUT” position.

The fan will switch on when the humidity sensor detects that the humidity exceeds (SECTION 1), but only if the built-in light sensor (SECTION A) detects that there is no light in the room, and will run until the humidity sensor detects that the humidity drops to 70% or below (SECTION 5). The fan will then run for 15 minutes(SECTION 2) and turn 0m. Every 12 hours (SECTIONC3), the fan will turn on and then turn off after 30 minutes.

If a light comes on in the room while the fan is operating, it will stop operating immediately.

CONNECTION AND CONFIGURATION

IMPORTANT: All operations related to connection, adjustment, maintenance, and repair of the product should be performed only when the mains voltage is removed. And repair of the product should be carried out only when the mains voltage is disconnected (circuit breaker S1 in OFF position).

Regardless of the wiring diagram, the unit only operates when the circuit breaker S1 is closed. The fan can only be energized,

i.e., the circuit breaker S1 can only be energized when the front panel of the fan is closed.
To prevent the switches from malfunctioning, do not apply excessive force when setting.

SECTION 1. CONFIGURING THE BUILT-IN HUMIDITY SENSOR

The factory default humidity at which the fan switches on automatically is set to 70%. If required, the following humidity values can be selected: 50, 70, 90%. Or you can disable the built-in humidity sensor altogether. To do this, set the Humidity switch to the required value.

If the humidity sensor is disabled, the fan in IN mode will turn on when the lights are turned on and will run until the lights are turned off, and after they are turned off for the time set on the Timer switch. In OUT mode, the fan will turn on when the lights are turned off and will run for the time set on the Timer switch.

SECTION 2. SETTING THE SWITCH-OFF DELAY TIME

The factory default fan operation time after lights out is 1 minute. If necessary, you can set the fan operation time after lights out to 5, 15, or 30 minutes. Or disable the timer altogether. To do this, set the Timer switch to the required value.

SECTION 3. SETTING THE VENTILATION MODE

The factory default setting is 12 hours, after which the fan is switched on in ventilation mode and runs for 30 minutes, after which it is switched off. If necessary, it is possible to set the ventilation intervals: 6, 12, or 24 hours. Or disable ventilation altogether. To do this, set the Airing switch to the required value.

SECTION 4. SETTING THE INTEGRATED LIGHT SENSOR

The factory default light sensor sensitivity is set to medium (default 70%). If necessary, you can select light values of 50, 70, or 90%. Or disable the built-in light sensor altogether. It is recommended to reduce the sensitivity of the light sensor to 50% (e.g., for a room with a window) or increase its sensitivity to 90% (e.g, for a room with low light). To do this, set the Light switch to the desired value.
