FCU Thermostat with BAC net MS/TP, Factory Provider

Short Description:

Typical used in FCU air conditioning systems, with control a 3-speed fan and one or two water valves
Designed for BACnet MS/TP network with a PIC statement to further facilitate integration.
A PIC statement is supplied to be easily mapped back to a graphical user interface.
Self configuring / adjustable baud-rate senses the communication conditions of the current MS/TP network and match them.
LCD displays working status such as room temperature, set point, fan speed, etc. Makes reading and operating easy and accurate.
All models feature user-friendly setting buttons
Large set point range, the min. and max. limit of temperature presetting by end users
Low temperature protection
Celsius or Fahrenheit degree selectable
Infrared Remote Control (optional)
Blue backlight (optional)

FEATURES

Especially designed for agriculture equipments such as greenhouses, food and vegetable storages. Real-time detecting CO2 level, temperature and humidity with the local programmable control.
Wall mounting, LCD display
Carbon dioxide sensor, temperature sensor and humidity sensor are internal. The three values can be apart set.
Non-Dispersive Infrared Detector (NDIR) CO2 sensor, more than 10 years lifetime
CO2 range: 0~5000ppm / 0~20000ppm/ 0~50000ppm
Special ABC Logic with patented Self Calibration Algorithm makes the CO2 sensor used up to more than 10 years
Temperature setting range: 5~45℃ Humidity setting range: 5～95%RH
Provid three relays outputs to control a CO2 generator, a temperature device and a humidity devise or a ventilator.
Special photosensitive sensor detection can make the working mode of the CO2 generator changeover automatically in day and night.
Provide brightness adjustment range to make day/night limit setting by end users.
RS-485 communication interface with 15KV antistatic protection makes the controller being connected with PC
Multiple functions, high performance, low price, make it praiseworthily.
