WCD2 PARAGONc
Installation – Condensation sensor 20180315
General description of the Condensation Sensor WCD2 - PARAGON.
The Sensor WCD2 PARAGON is designed to meet the requirements to provide early warning of condensing conditions.
In case of a problem with the system the sensor is used as a safeguard to avoid condensation from the chilled beam.
The sensor operates on dew point temperature rather than a fixed value of relative humidity.
The dew point is calculated from a temperature compensated RH element and a high accuracy thermistor which are
thermally bonded to the metal plate of the sensor.
The volt-free contact relay in the sensor is activated when the dew point temperature is below the calculated dew point
temperature (there is a safety factor included in the calculated dew point).
LED Indication.
The red LED, visible through the top of the housing, has 4 functions.
1. Short blink once every 15 seconds to show the device is working properly
2. Rapid continuous blinking to show the dew point switching set point is close
3. Continuously ON when the output is switched on.
4. On long flash followed by 2 short flashes to show the temperature element is faulty.
