Selector and Thermostat Characteristics

The tables show the operating characteristics of the selector and thermostat positions. The
selector and thermostat are potentiometers (variable resistors) whose resistance varies per user
selections. The selected resistance informs the board of the user's selections. All values are
approximate.
