This guide shows you how to connect a 240 VAC Variable-Speed Pump to a Intermatic Multiwave Pool/Spa Control System Model # PE653RC. See our guide on "How To Set Up the Intermatic PE653RC Pool-Spa Control System -Overview" for a basic understanding of how pool equipment is connected to the PE653DC Control System. Typically pool equipment, including a 1 or 2-speed pump, is connected to one of 5 control cuircits. However, a special connection is provided for a variable speed pump.
VIEW STANDARD PUMP CONNECTION - This is how a 240 VAC 1-speed Pump is connected to the PE653RC Control System. Generally a 1-speed pump motor will have two terminals labeled L2 and L1 plus ground. L2 will go to a breaker in the power supply box and L1 will go to terminal 3 of the Control Box. The circuit will be closed with a switch between terminals 2 and 3 as shown. The switch is controlled automatically through a user programmed setting or manually through Button 1. When this circuit is "ON" the LED light above Button 1 will illuminate. Since a VS Pump has its own programming control, it has to be controlled differently and will have a unique control interface to the PE653RC Control System.
VIEW VS PUMP WIRING - This picture shows how the VS Pump is wired to the PE653RC Control System. If you use 240VAC Supply Power to terminals 1 an 2, as shown here, the Voltage Selection Switch must be set at 240V. To wire the VS Pump, connect one end of the RS485 control cable to VS Pump and connect the other end to the VS Pump connector on top of the PE653RC Control System. Refer to the VS Pump manufacturer User's Manual for specific wiring instructions on the Pump end. The cable is Polarity Sensitive and the two wires must be installed correctly for proper operation.
PROGRAM VS PUMP OPERATION - The PE653RC Control System Remote Controller is used to program an IntelliFlo® or IntelliPro® VS or VF Pump. Once programmed ht e Remote Controller can also be used to manually change between four motor speeds by pushing 1 or 4 buttoms. See page 49 of the Intermatic PE653RC Installation and User Guide for detailed instructions on configuring the Variable Speed Pump.
