3. AdjustmentThe adjustment of the balancing unit is done by moving the movement limiters of the damper motor. As a factory setting, the movement limiters are set so that the damper opens and closes completely. The amount of supply air entering the room through the unit should correspond to the amount of extract air from the cooker hood.

Air quantity measurement is always done from the valve. The valve must be adjusted according to the boost ventilation.

Boost air flow adjustment (hood’s damper open) If 25 l/s is taken from the cooker hood during boost, the balancing unit’s damper should be fully open to avoid excess pressure loss in the duct system. In this case, the movement limiter of the damper motor is set to A position.

Basic air flow adjustment (hood’s damper closed) When the movement limiter of the damper motor is set to position B, the damper of the balancing unit is fully closed when the damper of the cooker hood is closed. If the basic airflow from the cooker hood is strived to compensate with the unit, the movement limiter must be moved so that the damper of the unit does not close completely.

4. UseOnce the balancing unit is installed and adjusted, it works automatically balancing the underpressure caused by the Central cooker hoods boosted or basic airflow to the room space via the supply air valve.

CHB Balancing unit

CHR24V Auxiliary relay 24 VDC for kitchen cabinet

The balancing unit for the cooker hood makes it possible, via a terminal, to balance the negative pressure caused by boosting the Central cooker hood and from general ventilation (basic air fl ow). The unit’s control damper opens and closes automatically based on a position signal from the cooker hood’s damper.The product CHR24V is used in hoods when you wish to control a balancing unit (CHB) and at the same time get a more accurate air volume from the centralised ventilation unit when each cooker hood communicates directly with a Swegon ventilation unit.

The ventilation in a high-rise building can be balanced with the help of a balancing unit. The unit compensates the negative pressure that boosting the cooker hood and the gen-eral ventilation (basic air fl ow) gives rise to by automatically opening a control damper and increasing the supply air to the home.
