Note: To avoid mismatching or crossing cell connections, each cell and cell cord should be
appropriately labeled with markings to identify them. AquaCal AutoPilot, Inc. recommends using
a marking system of A-1, A-2, A-3, etc. for each cell and cell cord, then marking the power supply
with PS-A and Tri-sensor with TS-A, etc. If additional units are used, they should be labeled B-1,
B-2, PS-B, TS-B, etc. to guarantee that no wires or cords become crossed.

When an ORP chemical controller is interfaced to your Pool Pilot
®
Professional, and does not
provide a Dry Contact ORP signal, the AutoPilot
®
ORP Relay Box (part # 110-ORP) is required.
For ORP controllers with an ORP Dry Contact Signal, it can be wired directly to the units ORP IN
terminal. The controller will control chlorine output. Once connected, as the controller
measurement falls below the set point, the unit is activated to produce chlorine until the set point
is satisfied. Check your local commercial guidelines for minimum and maximum ORP levels.
CAUTION - Failure to heed the following may result in equipment damage.
l The remote connections are compatible with either dry contact closure or solid-state relay. Do not
energize these inputs! Damage to the control panel will occur and the warranty will be voided.
