Function

The electric air heater heats the air flowing through it to up to 50 °C, depending on the setting of the ETL or DTL temperature control system.

The LW 9 air flow monitor monitors the flow velocity of the air passing in front of the fan.

ERH…R/DRH…R: The electric air heater heats the air flowing through it to up to 50 °C, depending on the setting. The integrated control system monitors and regulates the temperatures measured in rooms and in the ventilation channel.

The room temperature can be determined using the external setpoint controller. The desired room temperature can be set on the side dial.

The channel sensor measures the air temperature of the air flowing past in the channel (downstream of the electric air heater).

The minimum/maximum permissible temperature in the channel can be limited using the two setpoint controllers on the electronic circuit board.
