If your system is configured to use the reversing valve and
you only have one stage of heating and cooling, that last
relay becomes available for other uses. The AUXILIARY
RELAY MODE can be used to operate the relay manually
from the Prism computer front end program. If you select
ISOLATION VALVE MODE, the relay activates anytime
the compressor is called for or whenever the Loop Controller
sends an override command to activate and reduce loop
pressure.
If the relay needs to follow an external week schedule, select
the AUXILIARY RELAY MODE and then see the Aux
Relay #5 Schedule assignment screen.
You can program the fan to run continuously during the
occupied mode, (RUNS CONTINUOUS MODE) or you
can program it to cycle on and off with the compressor
during both the occupied and the unoccupied mode of
operation.

If you configured relay #5 as an Auxiliary Relay, you can
also program it to follow an external schedule command.
You must have an OSS Optimal Start Scheduler installed
somewhere on you communications loop to provide the
external schedule you select here.
