The controller provides abundant external ports such as RS485 ports, CAN
ports, FE ports, and USB ports that are protected by a security mechanism.
The device supports communications protocols such as Modbus RTU, Modbus
TCP, and SNMP, facilitating connection to the network management system
(NMS).
The controller intelligently identifies abnormal parameter settings (incorrect
commands) and rejects them automatically.
If the indoor temperature fluctuates beyond the normal range, an audible and
visible alarm signal is sent automatically.
