Display panel and buttons introduction
Buttons from top to bottom, from left to right as follows: power key; Set button; alarm mute button, OK button; up key,
down key. For operation of the controller
Parameter settings and Operations.
The controller displays the measured temperature and the humidity measured under normal conditions,smaller bottom
display shows the measured humidity and smaller bottom display shows the measured humidity.Display "El" when the
temperature sensor failure. "E2" when humidity sensor failure.
1.Parameter setting method
Control temperature setting.
Under the normal conditions,press the setting button for more than 3s the "temperature setting7'indicator lights;
temperature display shows the current stop control temperature and the humidity display shows "SEt".Then press
can adjust the control temperature,when adjusted to the appropriate expectations,press the OK button to confirm,all values
be saved and enter the hysteresis temperature setting.The "hysteresis temperatureHindicator lights.Temperature display
shows the hysteresis temperature and the humidity display shows^H^Then press can adjust the compressor
hysteresis when adjusted to the appropriate expectations,press the OK button to confirm,all values be saved and enter the
temperature correction setting.The "correction settingMindicator lights.Temperature display shows the correction
temperature and the humidity display shows "ot"Then press ,can adjust the correction value when adjusted to the
