No Controls (relays, etc.)
should be mounted in the Smart
Panel enclosure or connected to
power supplies in the control
panel. Additionally, control wir-
ing not connected to the Smart
Panel should not be run
through the cabinet. This could
result in nuisance faults.
Any inductive devices (relays)
wired in series with the flow
switch for start/stop, into the
Alarm circuitry, or pilot relays
for pump starters wired through
motor contactor auxiliary con-
tacts must be suppressed with
YORK P/N 031-00808-000 sup-
pressor across the relay/
contactor coil.
Any contacts connected to flow
switch inputs or BAS inputs on
terminals 13 - 19 or TB3, or any
other terminals, must be sup-
pressed with a YORK P/N 031-
00808-000 suppressor across
the relay/contactor coil.
Control wiring connected to
the control panel should never
be run in the same conduit with
power wiring.
