Test S: The Auxiliary Temperature and Panel/Floor Control Is Inoperative/Does Not Operate Correctly
PINPOINT TEST S: THE AUXILIARY TEMPERATURE AND PANEL/FLOOR CONTROL IS INOPERATIVE/DOES NOT OPERATE CORRECTLYS1-S3:

S5-S6:
Normal Operation
Under normal operation, the panel/floor and cool/warm signal is received by the smart junction box (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
