1、 Characteristics:

1. The humidity controller checks the humidity.

2. The controller is equipped with a built-in watchdog circuit, which has strong anti-interference ability; And it is equipped with an EEPROM chip, which automatically saves parameters in case of power failure.

3. The controller can set the upper and lower limits of temperature and humidity according to different humidity control needs. And there is a time control method.

1，Set parameters:

ØSet lower temperature limitDuring normal operation, press the SET key to enter the setting state of the controller, and the digital display will show "Ed". Press the ▲ key to display "HL" on the digital display, and then press the ENT key to set the lower humidity limit. Press the ▲▼ keys to modify data, press the ENT key to save data, and automatically enter the next parameter setting.

ØSet humidity upper limit:When selecting parameters, press the ▲▼ keys until the digital display shows "HH", and press the ENT key to display the humidity upper limit value on the digital display. After modifying the parameters, press ENT to save the data and proceed to the next parameter.

ØSet working hours:When selecting parameters, press the ▲▼ keys until the digital display shows "PC", and press the ENT key to display the working time value on the digital display. After modifying the parameters, press ENT to save the data and proceed to the next parameter.

ØSet interval time:When selecting parameters, press the ▲▼ keys until the digital display shows "FF", and press the ENT key to display the working time value on the digital display. After modifying the parameters, press ENT to save the data and proceed to the next parameter.

When "Ed" is displayed, press ENT to save the data and proceed to the next parameter.

2，Humidity calibration:When working normally, press the SET button for more than 5 seconds to enter the humidity calibration state of the controller. The digital display shows "HC", press the ENT button to display the calibration value, press the ▲▼ button to modify the data, and press the ENT button to save the data. And "Ed" appears, press the ENT key to exit the parameter settings.

1、 Controller job description

1，Humidity control:

When the actual humidity is less than the lower limit of humidity, the corresponding relay closes and outputs;

When the actual humidity exceeds the humidity upper limit, the corresponding relay will release

2，Time control:Set the working time to be greater than 0, and the controller will enter time control mode. The controller controls the output according to the set time; Working time (output) - Interval time (stop) - Working time (output) - Interval time (stop) -... Loop output. Set the working time to 0 and the controller enters automatic control mode.
