Universal Air Conditioning Controller SPD-AIR-S1
SPD-AIR-S1 is a universal air conditioning controller with a MODBUS interface. It has a learning function, which enables it to learn the control codes of the air conditioning remote controller, thereby replacing the remote controller to control the air conditioner. It also has a batch download and batch import function. Through the configuration software, it can conduct batch data acquisition and batch download, saving operation time. It has remote control and automatic control functions, which can be selected as needed. It is equipped with an internal temperature and humidity sensor, and the temperature and humidity can be displayed through the LCD. It comes with an RS485 interface that supports the MODBUS-RTU protocol. For PLCs, single-chip microcomputer control systems, Force Control, GroupWare, Kunlun Tongzhi, and other configuration software that support this protocol, SPD-AIR-S1 can be used to automatically control most cabinet-type or wall-mounted air conditioners.
Functional Features
a. With our accompanying software, 99.9% of air conditioner remote controls can be learned.
b. 23 groups of key functions can be learned.
c. It has a 485 interface and can control the air conditioner through the MODBUS-RTU protocol instead of the remote control.
d. Batch summoning and downloading of 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 10-30V.
g. The communication distance of the 485 communication line can reach up to 1000 meters.
h. Remote control of two air conditioners from one host.
i. Remote collection of the temperature at the location of the air conditioner controller.
j. Remote timed switching of the air conditioner.
k. Automatic switching of the air conditioner 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 a power-off protection function, and the set parameters are saved during power failure.
o. Configured with an air conditioner power-on self-start function. After power failure and re-powering, the device automatically sends the "custom channel 20" command.
p. Supports external infrared probes, and the infrared transmission extension cable can reach up to 5 meters.
q. Supports detection of the air conditioner's operating status.
