5.5 Two Speed Relay
5.5.1 Operation
1.
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, Line 2 and the two speed
relay common. If the two speed relay coil wires are deactivated, the motor runs at high speed. When the two speed
relay coil is activated, the motor switches to low speed.
2. If the two speed motor is the fi ltration pump, plug the relay coil wires for the standard relay into the fi lter pump
relay socket. Next, plug the two speed relay coil wires into the Auxiliary 2 socket. Finally, turn on DIP switch 2 to
set the circuitry to two speed operation. This will interlock the low speed and high speed together. If low speed is
activated, the control will turn on high speed fi rst for three (3) minutes (to prime the system) before switching to
low.
3. If the two speed motor is in a dual equipment system, plug the relay coil wires for the standard relay into the
Auxiliary 7 socket. Next, plug the two speed relay coil wires into the Auxiliary 2 socket. Finally, turn on DIP
Switch 2 to set the circuitry to two speed operation.
Note: Turn off the power to the system before moving any DIP Switches.
