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.
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.
Resistance checks are made on the thermostat wire harness with the thermostat wire harness disconnected
from the board at location P15. The harness is connected to P15 for voltage checks.
