This controller measures humidity and provides on-off control of humidifiers and dehumidifiers via a dry contact.
The controller continuously displays the ambient humidity and the requested setpoint.
Suitable for controlling relative humidity in wineries, ripening rooms, cold rooms, laboratories, industrial workshops, homes, etc., where high-precision relative humidity control is essential.
The DZR4020 controller must be equipped with a
ELIWELL HS2840 relative humidity sensor (optional).
Description : On-off control cabinet - DZR4020
The DZR4020 control panel is equipped with an ELIWELL DR4020R controller and a circuit breaker.
The DZR4020 control panel must be equipped with an optional ELIWELL HS2840 relative humidity sensor (0-100 hr).
For applications in drying rooms, we recommend using the RH and temperature probe HS-91 with heating element (optional).
