One points table covers all three models; which objects exist depends on the model and on the application code (0-18) set in the thermostat, and the table marks each object as always present, absent, or present only for listed apps. The list covers the relays and analog outputs, room temperature and humidity, setpoints, mode, fan speed, occupancy, enable, error code and running status.",
