Notes:
1. Switch T6 is not installed on units with steam coils. These
units are wired to provide a constant, no-fault condition.
2. High pressure switch HP is not installed on AV/AH units.
Only low temperature switch T4 is connected to DI-14
on these units.
3. High pressure switch HP and low temperature switch
T4 are wired in series on AZ units only.
