1. General Our controllers connects the digital T&H sensors and display the values on the panel. They have the fan contact, the heater contact and the alarm of detection of heater or sensor. They can also be equipped with RS485 port or alarm output to realize transmitting data or controlling in long distance. The users can program the points of alarm, the display and communication by the keys. And they have good advantages of anti-jamming and reliability. They comply the standard ofIEC15304 (Note: Because they use the digital T&H sensor, they have a better cost than other sensor. But they measure and control only in the air, such as computer room, warehouse, room of electricity distribution etc..) 2.
