● 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
identies abnormal parameter settings (incorrect
commands) and rejects them automatically.
● If the indoor temperature uctuates beyond the normal range, an audible and
visible alarm signal is sent automatically.
