Examples of model selection
Example 1
This project consists of 3 LSQWRF60VM/NaA-M, one control panel and BMS. The maximum
communication distance is within
800m. The BMS interface is RS232 and one converter is required.
Name Code Quantity
Air conditioning system EL01500720 1 (3 LSQWRF60VM/NaA-M)
Optoelectronic converter EN02200020 1
Example 2
This project consists of 7 groups LSQWRF60VM/NaA-M, six groups concluding 3 and the other
concluding 1. Seven control
panels are required. The communication distance is larger than 800m but be
or less than 1600m. One repeater is required for
somewhere the communication distance is over 800m.
The BMS interface is RS485.

Example 3
This project consists of 35 air conditioning systems including 103 LSQWRF60VM/NaA-M units. Among
then, there are 34 air
conditioning systems which consists of 3 LSQWRF60VM/NaA-M. The remaining
consists of 1 LSQWRF60M/NaA-M. Totally 35 control panels are required. A repeater is required for
somewhere the communication distance is over 800m but less than 1600m and
when the communication
nodes (control panels) exceeds 35. The BMS interface is RS232. Besides, one converter is required.
