This HVAC sensor controller measures temperature and relative humidity in air ducts and directly controls an EC fan, an AC fan speed controller or a damper actuator via the single analogue output and Modbus RTU.
The dew point is calculated using the measured values. The power supply is 24 V DC or 24 V AC. The output type can be selected. Via Modbus RTU all measurements and the output value are available and all settings can be adjusted.
