MST20S

Description

MST20S LCD Non-programmable unity control panel is designed for DPC series microcomputer programmable controller usage. it has a large-scale LCD, which can display input point value of DPC programmable controller (from temperature sensor, humidity sensor, etc.).

This panel has eight operates button for controls like start; stop; change humidity or temperature setting value). This panel adapt to be used for user request at scene need timely examine all sorts of numerical value or timely make operation.

Features

• Use 16 bit microprocessor, high precise operation.
• Adopt RS- 485 two-wire communication network (4 wires in total with power line), consists with MODBUS RTU format.
• Large size back light LCD panel. Convenience during the night operation.
• Selectable usage for air conditioning, central heating, constant temperature, constant temperature and humidity application.
• Can show temperature, humidify, dew point, temperature sets up value, humidity sets up value, fan coil running state and cooling, heating, de-humidify status.
• Can set temperature, humidity value and control fan start/stop.Celsius or Fahrenheit unit selectable for Temperature display.
• Can display DPC time format, time coincident by the time synchronization.
• Can manual control cooling, heating, humidify, dehumidify as benefit maintain and test.  When manual operation, an icon will bring user’s attention.
• Display alarm code voice alarm message for a new alarm. It has alarm history for checking. The alarm history can me deleted by authorized personnel. Buzzer can by turn off.
• Included self wakeup function (Watch Dog) when software is down.
• Password setting for a general operation and a parameter setting to prevent unauthorized operation.
• Has parameter mode, which can display and control input (AI/ BI) and output (AO/ BO) status and all inside parameter numerical value (AV/ BV) of DPC.  In parameter mode, output (AO/ BO) points permit priority control.
