Universal Air Conditioner Controller SPD-AIR-S1
SPD-AIR-S1 is a universal air conditioner controller with a MODBUS interface, featuring a learning function that enables it to learn the control codes of air conditioner remote controls and thereby replace the remote control to operate the air conditioner. It has batch download and batch import functions, allowing for batch measurement and batch download through configuration software, saving operation time. It also has remote control and automatic control functions, which can be selected as needed. It is equipped with built-in temperature and humidity sensors and can display temperature and humidity on the LCD screen. It has a built-in RS485 interface that supports the MODBUS-RTU protocol. For PLC, single-chip microcomputer control systems, ForceControl, Kingview, and KUNLUN Tongtai and other configuration software that support this protocol, SPD-AIR-S1 can be used to automatically control most floor-standing or wall-mounted air conditioners.
Functional Features
a. Through our company's supporting software, 99.9% of air conditioner remote controls can be learned.
b. It can learn 23 groups of key functions.
c. It is equipped with a 485 interface and can control the air conditioner by replacing the remote control through the MODBUS-RTU protocol.
d. Batch call and download learning codes.
e. The ModBus communication address can be set and the baud rate can be modified.
f. The SPD-AIR-S1 device is powered by a wide voltage range of DC 10 to 30V.
g. The communication distance of the 485 communication line can reach up to 1000 meters.
h. Two air conditioners can be remotely controlled on one host.
i. Remotely collect the temperature of the location where the air conditioner controller is located.
j. Remotely set the air conditioner to turn on and off at scheduled times.
