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.

Resistance checks are made on the selector wire harness with the selector wire harness disconnected from the
board at location P21. The harness is connected to P21 for voltage checks.
