MultiWave™ ECS Plus System Basic Wiring

Intermatic MultiWave ECS Plus System
This video will show you how to wire and install the MultiWave ECS Plus System, which is 80 amp and has a 8-breaker base.
Intermatic’s MultiWave Wireless Control Systems are perfect for retrofit or new construction.

We’ve mounted the PE30,000 load center.

Before beginning any wiring, be sure to turn off the power at its source.

The load center has two openings for mechanisms; 8 breaker knockouts; 4 bottom knockouts for switches or receptacles; and 1 side knockout.

Breakers are sold separately. Check the inside front panel for a list of acceptable types.
Remove the dead front on the panel to install the MultiWave receiver.
The receiver comes shipped attached to a small enclosure box. Unscrew the nut and gasket to remove the receiver. Mount the receiver to the top right knockout, using the nut and gasket to keep the unit raintight.
Open the door on the receiver and make sure the selector switch is in the correct position. The receiver is factory set for 240 volt operation. Refer to the installation manual for 120 volt.

Now we can wire to the breaker:
One side of the double pole breaker goes to terminal 1; the other side goes to terminal 2. This will supply power to Circuits 1 and 2 on the PE653 receiver.

Circuits 3,4 and 5 will be explained in future videos.
We’ve snapped in the Expansion Module, which allows you to control two bodies of water. Connect the black and red wires from the module directly to a constant 240-volt power source.
Now remove the top plate from the expansion module to establish the communication line to the receiver. Run the wiring from the RS485 terminal on the module through the raceway since this is low voltage. The connectors are labeled A and B. The A terminal connects to the outside (or right) terminal of the receiver. The B terminal connects to the inside (or left) terminal of the receiver. It’s important to note that these connections are polarity sensitive.
Now we can wire the water temperature sensor. Make sure the location for the probe is after the filter but before the inlet to the heater. Drill a 3/8-inch hole and insert the water sensor probe. Secure it with the provided hose clamp. Make sure the probe’s o-ring is in place.

Run the sensor wires to the receiver and insert both wires to the middle terminals on the 6-pin terminal block. These are not polarity sensitive.
