Application
- Wall ventilator with heat and energy recovery.
- Supply clean fresh air to the premises.
- Control via remote control.
- Remove stale extract air from the premise.
- Clean the air of dust and insects.
- Prevent penetration of excessive humidity and appearance of mould.
- Protect against outdoor noise.
- Heat return and ensuring the balance of humidity in the room thanks to the built-in humidity sensor.
- Reduce the heating costs in winter and air conditioning costs in summer.
- Low energy demand
Design
Fan
- Air is supplied or extracted by a reversible axial fan with EC motor.
- Due to EC technology the fan is distinguished with low energy demand.
- The motor has overheating protection and ball bearings for longer service life.
Energy Heat Exchanger
- The high-technology ceramic energy heat exchanger with recovery efficiency up to 85 % is used for extract air heat energy recovery and supply air heating.
Air Filters
- Two built-in filters with total filter class G3 are used to clean supply and extract air flows.
- The filters ensure fresh air cleaning of dust and insects and prevent the ventilator parts from soiling.
- The filters are cleaned either with a vacuum cleaner or flushed with water.
Humidity Sensors
- Helps control the level of humidity in the room.
- When the sensor is activated, if the humidity in the room exceeds the set level, the ventilator switches to the second (higher) speed.
- The humidity sensor threshold can be adjusted by turning the potentiometer knob with a special plastic screwdriver.
- The humidity sensor can be switched on and off using the remote control.
Control
1. The humidity sensor and speed are controlled by the remote control.
Operation Logic
Energy is recovered due to reversing operation of the ventilator, which consists of two cycles:
- CYCLE I. As warm stale extract air flows through the ceramic heat exchanger, it heats up and moisturizes the heat exchanger. In 60 seconds as the ceramic heat exchanger gets warmed the ventilator automatically switches to Air Supply mode.
- CYCLE II. Fresh, cold intake air from outside flows through the ceramic heat exchanger, absorbs accumulated moisture and is heated to the room temperature. In 60 seconds as the heat exchanger gets cooled down, the ventilator switches to Air Extract mode and the cycle is renewed.
- The Air Supply and the Air Extract modes are switched every 60 seconds.

Application
1. Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces.
2. Ventilation shaft mounting or duct connection.
3. Low to medium air flow motion for short distances at low air resistance.
4. Compatible with Ø 100-, 120-, 125- and 150-mm air ducts
Design
1. Modern design and aesthetic look.
2. The casing and the impeller are made of high-quality durable ABS plastic, UV resistant.
3. Various decorative plates for the front panel of the natural aluminum.
4. The intellectual impeller design makes the fan efficiency high and the service lifelong.
5. Protection rating IP34.
Mounting
1. The fan is mounted directly into the ventilation shaft.
2. In case of remote location of the ventilation shaft flexible air ducts may be used. The air duct is connected to the fan exhaust flange through a clamp.
3. Fixed to the wall by means of screws.
4. Suitable for ceiling mounting.
5. To connect a fan with a 12 V low voltage motor to 220 V/50 Hz power mains, it is necessary to purchase a step-down transformer (e.g. the TRF 220/12-25 transformer)
Motor
1. Reliable and low-watt electric motor.
2. Designed for continuous operation and requires no maintenance.
3. Equipped with overheating protection.
Speed Control
Manual:
1. The fan is controlled by a room light switch. It is not included in the delivery set.
2. The fan is controlled by the built-in pull cord switch V. Not applied in case of ceiling mounting.
3. Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may be connected to the same controller. Speed controllers can not be connected to the fans with Т, ТН, ТР, VТ, VТН modifications.
Automatic:
1. By the BU-1-60 electronic control unit. The control unit is supplied separately.
2. By the T timer (the built-in turn-off delay timer enables the fan operation within 2 to 30 minutes after the fan switching off).
3. By the humidity sensor and the TH timer (if the humidity level in the room exceeds the sensor threshold adjustable value within 60-90 % the fan switches automatically on and operates until the humidity level drops to the standard level, after that the fan continues operating within the time period according to the timer setting, then shuts down).
