MST20S individual LCD control panel is designed to work with any type of AIRTEK DAC/DSC series controller which has MSnet port. It is a two-wire RS485 communication transmission interconnection with the controller. It may facilitate the user to access, examine, setting, change and confirm each kind of control parameter value from DAC/DSC controller. For example, temperature value, humidity value, device operation status, and alarm messages, enable output points start/stop, changing the temperature and humidity setting values,etc. MST20S has a 3 inch LCD with backlight and eight operation buttons, let users operate easily and friendly.
