If the transformer (T2) is to power all of the loads, the
yellow pin jumper must be inserted connecting
R to 24 V. The jumper is located on the electronics board
above the relays. If a separate 24 V transformer (T1) is to
be used, it must be connected between R and 24 V(c), and
the jumper should be removed between R and 24 V.
