Description
This is a digital humidity controller with wide humidity measuring and control range. There's 1 relays on this controller. Humidification and Dehumidification modes can be set through the menu.
Dehumidification Mode Example:
If you want a dehumidifiers to be turned on at 95% and turned off at 85%. Set the controller to Dehumidification mode, set target humidity to 85 and set differential value(humidity span) to 10. Once detected humidity is above 95%, the controller turns on dehumidifiers. Once detected humidity reaches 85%, the controller turns off dehumidifiers.
Humidification Mode Example:
If you want a humidifiers to be turned on at 60% and turned off at 80%. Set the controller to Humidification mode, set target humidity to 80 and set differential value(humidity span) to 20. Once detected humidity is below 60%, the controller turns on your humidifiers. Once detected humidity reaches 80%, the controller turns off the humidifiers.
