Description

Our Digital Humidity Controller makes managing relative humidity (RH) in your growing and drying spaces so much easier.

The unit is versatile and can be used in a number of ways depending on which operating mode you select and how you wire up the unit.

There are 2 simple modes of operation, where the unit will turn equipment on when the humidity drops below a set % ( Humidification mode ) OR the unit will turn equipment on when the humidity rises above a certain % (Dehumidification mode).

For more advanced users, two sets of equipment could be operated with the digital humidity controller. Here, the default circuit ( called Normally ON / Normally CLOSED ) will be used to constantly power equipment, UNTIL such time as the switching conditions are met.

  • Dry Weather Example: A humidifier will continuously operate UNTIL the RH goes above a certain %, at which point the controller will “flip over” the normally active circuit, powering down the humidifier and turning on the alternate circuit ( connected to, for example an extraction fan ) which will operate until the RH drops to below the set %.
  • Wet Weather Example: A dehumidifier will continuously operate UNTIL the RH drops below a certain %, at which point the controller will “flip over” the normally active circuit, powering down the dehumidifier and turning on the alternate circuit ( connected to, for example a misting unit ) which will then operate until the RH increases to above the set %.

The unit can be programmed in various other ways, which include the % drop or increase before circuit is switched over, ON time delays ( To prevent damage to equipment ) and it also has an emergency mode feature, where equipment will be turned on for preset amounts of time in case of RH probe errors.

The unit runs off 220V AC, which means no additional AC Adaptors / Drivers are needed to power up the unit itself.

Please note that the controlled equipment will still require their own power sources ( the unit does not provide power to the equipment, it only engages or disengages their circuits ) PLEASE USE RESPONSIBLY – Get a professional to help you if you feel unsure about your wiring.

Unit includes RH probe only, no additional electrical wires or plugs are included.
