Ⅳ、The operation illustration：

4-1、Powering on after connecting the controller correctly to according to the connection scheme, the controller starts testing itself for 1 second, then, it displays measured humidity value.

4-2、Humidity setting value set: Press ▲ or ▼ key for 3 second，the set value and “”display by turns，press ▲ or ▼ key to adjust, press SET key to save it and exit. If you do not press any key and wait 10 second, the meter autosave and exit.

4-3、Inner parameters modify:

Press SET key for 3S to enter into the parameters modification status, the parameter code and parameter value display by turns，press ▲ or ▼ key to adjust parameter value, for long time press the key can accelerate. After modification, press SET to save and enter into the next parameter modification status. If you don’t do any operation halfway, the meter will wait 10S, autosave and exit.

Ⅴ、Controller Output：  

5-1、When =0：

When the humidity measured value≥Humidity setting value（）＋Control of return difference（），controller has dehumidifying output (output relay is closed)，the OUT indicator light on； When the humidity measured value≤Humidity set value（）－Control of return difference（），controller has not dehumidifying output (output relay is opened)，the OUT indicator light off；

5-2、When  =1：

When the humidity measured value≤Humidity setting value（）－Control of return difference（），controller has humidifying output ( output relay is closed)，the OUT indicator light on；

When the humidity measured value≥Humidity setting value（）＋Control of return difference（），controller has not humidifying output (output relay is opened)，the OUT indicator light off ； 

Ⅵ、Wiring diagram (consult)：

Ⅶ、Error：

When the humidity sensor is beyond testing range or open circuit, the controller will display100”.
