Operation:
The Two Speed Relay operates in conjunction with a Standard Relay to operate a two speed pump/motor.
The Standard Relay is the On/Off relay and the Two Speed Relay is the switching relay. Activating the relay coil for
the Standard Relay will complete the contact circuit between Line 1 and the motor common, and Line 2 and the Two
Speed Relay's Common. If the Two Speed Relay's coil wires are deactivated, its contacts make connection between
its Common terminal and its Normally Closed terminal and the motor runs at High Speed. When the Two Speed Relay
coil is activated, its contact makes connection between its Common contact and Normally Open contact, and the
motor switches to Low Speed.
If the Two Speed Motor is the filtration pump, plug the relay coil wires for the Standard Relay into the Filter Pump
Relay socket. Next, plug the Two Speed Relay's coil wires into Auxiliary 2. Finally, turn on DIP switch 2 to set circuitry
to two speed operation.
NOTE: Turn off power to system before moving DIP switches.
