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.
