Wiring the AquaSmart Control
Consult the appliance wiring diagrams to check the
manufacturer’s specifi cations.
Refer to Figure 12 through Figure 17 for some
typical wiring diagrams.
Verify the wires are still labeled correctly and make
connections to the appropriate terminals on the
control wiring terminal strip.
Provide disconnect means and overload protection
as required on power supply.
Connect control conduit bracket to earth ground
using the supplied grounding screw.
B1 terminal is a 1/4 in. tab terminal (quick connect).

How to calculate VA - Add all AMP ratings of 24VAC
components in this circuit and multiply sum by 24 volts.

When powering multiple circulators

from the C1 and C2 terminals, take
extra care not to exceed the output’s reading. If the sum
of the full load amps of all the circulators exceeds the
output’s rating, use the C1 and C2 terminals to power the
coil of a multiple-pole contactor; the contacts of which can
be wired to switch L1 to each circulator.
