Test S
PINPOINT TEST S: THE AUXILIARY TEMPERATURE AND PANEL/FLOOR CONTROL IS INOPERATIVE/DOES NOT OPERATE CORRECTLYTest S1-S2:
Test S2-S4:
Test S4-S6:
Normal Operation
Under normal operation, the panel/floor and cool/warm signal is received by the SJB from the rear auxiliary control through circuit 1121 (DG/YE). Reference voltage for the panel/floor and cool/warm signal resistor is provided by the SJB through circuit 1348 (GY/OG). Ground for the panel/floor and cool/warm signal resistor is provided by the SJB through circuit 1125 (BN).
Possible Causes
- An open, short to ground or voltage in circuit 1121 (DG/YE).
- A short together circuits 1121 (DG/YE) and 1348 (GY/OG) or 1121 (DG/YE) and 1125 (BN).
- Rear auxiliary control.
- SJB.
