2 Optional RB-J10-1 LTB1-R Power relay board It is recommended that the air handler
and condensing unit share low voltage
power. If the air handler and
condensing unit have separate low
voltage power, these conductors can be
omitted, but isolation relays are
needed on the remaining Control Wire
conductors.
