The SPD-AIR-S1 universal air conditioner controller is a MODBUS interface device with learning capabilities.
It can learn the control codes of air conditioner remote controls and replace them to control the air conditioner. It features batch download and import functions, allowing for batch measurement and 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 an RS485 interface that supports the MODBUS-RTU protocol. For systems such as PLCs, single-chip microcomputer control systems, ForceControl, Kingview, and KUNLUN-TRON, which support this protocol, the 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 instead of the remote control through the MODBUS-RTU protocol.
d. Batch call measurement 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 adopts wide voltage supply, and both DC 10V and 30V are acceptable.
g. The communication distance of the 485 communication line can reach up to 1000 meters at most.
h. Two air conditioners can be remotely controlled on one host.
i. The temperature at the location of the air conditioner controller can be remotely collected.
j. The air conditioner can be remotely timed to turn on and off.
k. The air conditioner can be automatically turned on and off based on the set lower and upper temperature limits.
l. Control failure alarm and relay output.
m. Over-temperature and low-temperature alarm and relay output.
n. The device is equipped with power-off protection function, and the set parameters can be saved after power-off.
o. It is configured with the air conditioner's power-on self-start function. After the power is cut off and then restored, the device will automatically send the "custom channel 20" command.
p. It supports external infrared probes, and the infrared transmission extension line can reach up to 5 meters.
q. It supports the detection of the air conditioner's operating status.
