The gateway is Modbus RTU (RS-485) and exposes its own fixed holding-register map that mirrors the indoor unit; reach it through a Modbus RTU-to-TCP gateway using the factory serial settings above (9600 bps, 8-N-2, Modbus server address 1; the gateway auto-detects 8-N-1 and 8-N-2). All registers are 16-bit unsigned holding registers, big-endian. The addresses in this file are the manual's base-0 'protocol addresses' (the manual also prints a base-1 'PLC address', which is always this address + 1). Temperature registers are signed 16-bit and their magnitude follows the gateway's DIP switches (degC x1, degC x10 or degF), so the 0.1 scale factors below assume the factory default degC x10; with the x1 setting the readings are whole degrees. This is the only one of the Intesis HVAC gateways in this library whose manual marks a group of temperature registers with a 0.5 °C decimal precision (footnote 4 of the manual); those rows carry a 0.5 scale factor and the rest the degC x10 default. Registers 4001 and up are per-indoor-unit status for the two indoor units the gateway can handle in master/slave operation."
