HUMIDITY SENSOR ZEHNDER EDA/MD 0-10V / 24V

Humidity transmitter for Enervent EDA and MD ventilation units. The humidity transmitter enables automatic control of the ventilation unit's fans. The %RH humidity transmitter measures the moisture content of exhaust air, for example when showering or using the sauna causes an increase in air humidity. The automation responds to the transmitter's readings, and when the humidity level exceeds the set thresholds, the fans increase ventilation to reduce air humidity. The recommended relative humidity in the room is 40–45% (room temperature 20–22 °C). Indoor air humidity is reduced by increasing ventilation. The humidity boost function of the automation can be turned on or off, and the operating principle for humidity boost can be selected: fixed threshold or 48-hour average. The IV unit has a built-in sensor for measuring humidity in the exhaust air. Additionally, two external humidity sensors can be connected to the ventilation unit as optional accessories.
