Product Description

NW24 Temperature Controller for Telecom Shelter is an economic solution for telecom remote monitoring management.

It can control the work of two air conditioners as well as the centrifugal fan based on the detected temperature by sensors.

Fire/smog, intruson, water leakage, motion, battery voltage, fan failure can also be monitored.

Real-time records temp, alarm code and work status, upload date via Mini USB port.

Output DC 0 to 10V PWM dry contact signal to centrifugal fan.

Output on/off switch signal to air conditioners.

Alarm signal output.

Function:
Program	every work temp. can be programmed
Display	LED display temperature, and alarm code
Auto control	control the work of two air-conditioners and EC fan based on indoor, outdoor temperature.
