The Pump Relay Box
comes with a ¾-inch
thread for mounting to
circulators. Some
manufacturers produce
pumps that allow for
two electrical
connections on the
motor housing. (See
Figure 4-13
.) When
this option is available,
the Pump Relay Box
will thread directly into
this tapping for easy
mounting. When this
option is not available,
use standard electrical
boxes with pump relays.

The Climate Co˘ntrol - Multifunction system offers additional flexibility and
can be daisy-chained — where two pumps turn on simultaneously (e.g., in a
heat exchanger application when the primary pump needs to turn on at the
same time as the secondary pump). The two connectors that come with each
Pump Relay Box are universal (i.e., the ports are not dedicated).
(See
Figure 4-12
