2、 Instructions for use
1. Wiring:
Connect the humidity monitor according to the following diagram during operation.

2. Working methods
When the humidity monitor is working normally, if the humidity is between the upper and lower limits, the output relay will not operate; If the humidity rises above the upper limit humidity, the upper limit control relay will activate and the normally open contact will close; If the humidity drops below the lower limit humidity, the lower limit control relay will activate and the normally open contact will close.
3. Installation and maintenance

3.1 On site installation
Shielded wires are used for electrical connection lines;
Please do not touch the circuit or adjust the potentiometer without authorization when wiring.
3.2 Installation Environment
