INSTALLATION

Connecting the #75003 Digital Control unit to any other external ORP controller (A Dry Contact closure must be provided and the Purifier % output must be set to 0%. Turn off power before making any electrical connections)

The ORP connection must be made to the internal ORP IN TERMINAL (marked TB2 on the lower Circuit Board) where indicated in the diagram above, and should send a closed circuit condition when the ORP level is below the set point. When the ORP set point is satisfied, the ORP controller should send an opened circuit condition, automatically deactivating the Pool Pilot. For ORP control systems not providing a dry contact closure, PN # 110-ORP Relay Kit is required.

! CAUTION

To avoid damage to the Pool Pilot Control Unit or voiding the warranty, do NOT

energize the ORP inputs! The ORP input is for dry contact use only.

Installing the Optional #110-ORP Relay Kit

Warning: Turn off power to the Pool Pilot Digital and ORP controller before connecting any wires. In the event that the ORP controller does not provide a dry contact closure, a standard 110 Vac output can be used with the 110-ORP relay kit to provide the dry contact closure.

1.Plug the ORP 110 Vac cord into the relay box’s 110 Vac cord.

2.Remove the two-position plug from the end of the interface cable.

3.Insert the Relay Kit’s interface cable through the Low Voltage Access Port, as shown above.

4.Connect the cable to the ORP IN Terminals, as shown in the diagram above.
