  • Page 12 Menu Description Factory setting (max./ min. values) EB – Fan level EB4 – Level 4 Supply Air is typically configured at 100% airflow for EB4: 100% rapid air exchange throughout the house. (0–100%) Remember that a higher air exchange rate increases energy consumption.
  • Page 13 Menu Description Factory setting (max./ min. values) EC – Regulator Vent. Reduc. = The fan speed for supply air is gradually reduced to keep the temperature sensor in the exhaust (T4) at the EC2 setpoint. Rotor Reduc. = Rotary heat exchanger speed is gradually reduced to keep the exhaust temperature sensor (T4) at the EC2 setpoint.
  • Page 14 Menu Description Factory setting (max./ min. values) EC – Regulator 6 The relay will be on when terminal L1 is shorted/activated (e.g. by connecting a kitchen cooker hood to the ventilation unit). This function can be used to activate a damper, which reduces the airflow to the rest of the house and focuses the exhaust air through the hood.
