The system mode refers to the type of fan coil system your thermostat is connected to. This setting should only be set once during the initial setup of your thermostat. Please see Installing your universal fan coil thermostat for more details.

Temperature offset

If the thermostat is in an area of the suite that is colder or warmer than the rest of the home, you can offset the thermostat’s temperature reading to compensate. Before you adjust this setting, you will need a thermometer to measure the temperature near the thermostat, and again in a room that feels similar to the rest of the suite. The difference in temperature
is what you need to offset the thermostat at. The Universal fan coil thermostat can be offset +/- 5 °C or 10 °F.
