Specifications

Telecom site environment remote monitoring
telecom site power monitoring
RS485 communication

It starts DC fans first to save energy, and controls them based on indoor temperature and humidity, outdoor temperature. Then controller starts air-conditioner if temperature is higher. Control logic is smart, simple and stable.

Function:
Set	Contains 4 buttons to set
Display	5 pcs of 0.56’’ LEDs and 4 pcs of LED lights
Control	Control DC fans and 2 air-conditioner based on temperature and humidity
Alarm	Output a alarm signal (dry node)
Power detection	AC power and battery voltage, if AC power off or voltage of battery is lower than DC 46V output alarm signal
Work state detection	Detect the frequency of fan to judge if DC fan has fault, and use current sensor to detect if air-conditioner has fault
Manual test	Start DC fans or air-conditioner by manual
Initialize parameter	Initialize running parameter by a combination key
Communication	Supply RS485 communication interface, and supply software for free
