The Modbus monitoring system is capable
of controlling up to 255 thermostats at the same
time. Communication between the thermostat
and the Modbus monitoring system is transmitted
at 9,600bps by default. The default address is 1
and you can set the address between 1~255. You
need to set different addresses to avoid conflict
recognition.

address setting page.

press within 20s, the current page will exit, not saving any data you set.
