The list covers outdoor, supply, return and exhaust temperatures, filter and fan pressures, humidity, CO2 and IEQ sensors, damper, fan, coil and humidifier signals, temperature, humidity, flow and pressure setpoints, defrost settings, switch and alarm inputs, outputs and a unit status BMS command. Object instances are fixed but non-sequential.",
