Configuration | Use up and down arrows or a slider to change the airflow value. The airflow may be adjusted in these steps: Off/Low/Normal/High. These settings control output signals to the sup- ply and extract fans. Important It is not recommended to set fan to Off in standard households. If manual fan stop is activated, the unit should be provided with dampers in exhaust and fresh air ducts to avoid cold draught and risk of condensation when the unit has been stopped.

| Accessories • SPI-125 C Iris damper — 6751 Installation and connection • Follow instructions in the manual which is delivered with the accessory. Installation/Maintenance 5.5.1 Outdoor/Exhaust air dampers If manual fan stop is activated, the unit should be provided with dampers in exhaust and outdoor ducts to avoid cold draught and risk of condensation when the unit has been stopped.
Accessories | Note: 24 VAC dampers can be powered and controlled only by using a relay mounting kit with a transformer (article number: 153548). This installation procedure describes how to connect dampers powered by 230 V~ with a relay mounting kit without transformer (article number: 153549).
| Accessories 1. A differential pressure switch 2. Metal tube 3. Exhaust air direction 4. Exhaust air duct 1. Mount a differential pressure switch in a suitable place, for example on or near the outlet duct from the kitchen fan. Set the pressure switch to the lowest possible pressure, for example 20 Pa.
Accessories | Note: • If the 24 V power supply on the connection board (CB) is used for other equipment, the number of control panels that can be powered from the unit will decrease. • A single active control panel draws 50 mA. The connection board supplies up to 250 mA. If no other accessories use 24 V power supply from the unit, up to 5 control panels can be connected without a need of external power supply.
