Product Usage Instructions

1. Functional Description – Balanced Ventilation

The UNI 4 Air Handling Unit & Automatic Control is designed
for balanced ventilation. It ensures proper air circulation and
temperature control in indoor environments.

1.1. FANS (M1, M2)

The fans (M1, M2) are responsible for circulating the air within
the unit. They should be properly installed and maintained to
ensure efficient operation of the unit.

1.2. FILTER (FI1, FI2)

The filters (FI1, FI2) ensure that the air entering the unit is
clean. Regular cleaning and replacement of filters are necessary to
maintain optimal air quality.

1.3. HEAT RECOVERY SYSTEM (HR-R)

The heat recovery system (HR-R) recovers heat from the exhaust
air and transfers it to the supply air. This improves energy
efficiency and helps maintain a comfortable indoor climate.

1.4. HEATING ELEMENT (EB1) (FOR UNI 4 E)

The heating element (EB1) provides additional heating when
required. It is important to follow the instructions for proper
installation and operation of the heating element.

1.5. TEMPERATURE SENSORS (B1, B4)

The temperature sensors (B1, B4) measure the temperature of the
outdoor air. This information is used to control the operation of
the unit and ensure optimal indoor climate conditions.
