EH3 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 that temperature sensor 2 is being
placed on the surface to be kept condensation-free, serves as
set point for the humidity controller. Temperature sensor 2 can
also be used for controlling the temperature
– Communication through modbus
– Additional displays

Two closing contacts: Possible to choose the source from one of the four parameters above for each relay. Used for controlling one dehumidifier in two steps or for controlling two separate dehumidifiers. It can also be used for dehumidifying on one relay and temperature control on the other.

Display and diodes: Two-row display where two parameters can be monitored. A green Normal LED and a red Alarm LED switch at a set value of any of the four parameters.

Analogue outputs: Two outputs with Vdc or mA, with the option to choose the source from the PI-regulator or one of the four parameters above.

PI-regulator: Two independent regulators are available as standard. This allows control of both humidity and 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 less than ±2 percent RH and less than ±0.5 degrees Celsius. Each sensor comes with a calibration protocol.
