The NST32V(-H) LCD temperature (humidity) sensor group control panel is designed to be used by DSC, DAC and VAV series microcomputer programmable controllers. It has a two-wire RS485 network communication capability and can communicate with up to 32 units. The programmable controller is connected to a community network. It has a large LCD backlit screen that can display the monitoring input points of the programmable controller (such as temperature sensing values, humidity sensing values, etc.) and six operating buttons to issue various commands (For example, start, stop, change the temperature and humidity setting value, etc.), this operator contains a temperature (humidity) sensor, and also has group control and channel selection buttons, you can select a single operation command or group operation according to your needs Group operation. It is suitable for occasions where the user needs to view various values or issue instructions in real time on the spot.
【Features】
- Made with microcomputer chip.
- It adopts RS-485 communication two-wire network communication transmission (including power supply must be equipped with four-core wire), compatible with MODBUS RTU format, and the information is accurate and stable.
- With software program crash self-wake-up function (WATCH DOG).
- Parameter selection can be used in applications for air conditioning, heating, and air volume control.
- The standard built-in temperature sensor can sense the temperature value of the position where the panel is located. Another type of built-in temperature and humidity sensor can be selected, and the controller can program various energy-saving control requirements.
- The temperature setting value and humidity setting value can be set, and the setting accuracy can be programmed, up to 0.1. The temperature display can be parameterized and displayed in Celsius or Fahrenheit units.
- With group and channel selection buttons, it is convenient for users to operate any single controller or perform global group operations.
- It can display the sensored air volume and wind speed parameter settings (maximum wind speed, minimum wind speed, damper opening degree.
- With LED backlight function, various values can be set and output, and the range, type and display unit of the value can be specified through the internal program planning.
- With real-time clock display, the internal clock format of the display controller can be controlled by parameters. Through the system time synchronization action, the function of master clock and master clock can be achieved.
- The output of cooling and heating can be directly controlled manually to facilitate maintenance and testing. When any item is output manually, the attention graphic will be displayed as a reminder.
- With general operation password control function, to avoid improper operation by unauthorized personnel.
- With parameter mode, it can display and control the advanced parameters in the VAV controller.
