Electronic humidistat and controller Relative humidity % RH Absolute humidity g/kg Dew-point °Cdp Temperature °C / K / °F Two independent regulators Possible add-ons: - Condensation-free thanks to the temperature sensor placed on the surface to be held condensation-free, serves also as setpoint for the humidity controller. - Communication through modbus - Additional displays Two closing contacts: Possible to choose source from one of the four parameters above to each relay. Used for controlling one dehumidifier in two steps or to control two separate dehumidifiers. Can also be used for dehumidifying on one relay and temperature control on the other. Display and diodes: 2 row display where two parameters can be monitored. Green “Normal” LED and red “Alarm” LED, switches at a set value of any of the four parameters. EH-3 T2 with back-lit display, available from Seibu Giken DST only. Analogue outputs: 2 outputs with Vdc or mA, choose source from the PIregulator or one of the four parameters above. PI – regulator: Two independent regulators are available as standard. You thereby can control both the humidity and temperature. Enables control for energy saving for the dehumidifier and can also control the temperature. Set the desired value for relative humidity, absolute humidity, dew point, liquid dew point and temperature and EH3 T2 will keep it constant. Sensor: Capacitive type moisture sensor from Honeywell with an accuracy of <±2%RH and <±0.5° C. Each sensor comes with a calibration protocol. Humidity- and temperature sensor from Honeywell (standard) Immersion sensor. (optional), also available for surface mounting

Measuring range: -30°C up to +80°C. 0-100%RH (not condensing) Accuracy: <±2%RH and <±0.5°C in the full measuring range RH stability: ±1% RH at 50% RH during 5 years Calibration: Each sensor comes with a calibration protocol for 0% RH and 75.3% RH. The sensor can easily be changed and after setting the calibration parameters on the display the <±2% RH accuracy is obtained again Response time: At low air speed, 30 seconds Mounting: 10 m sensor cable and wall mounting device included Optional: 20 m sensor cable Visual alarm: Height: 120 mm, depth 90 mm, width 122mm Green LED marked "Normal" and...
