Effortless Guide: How to Wire Multiswitch to Swamp Cooler in 5 Steps

Wiring a multi-switch to a swamp cooler requires a deep understanding of the technical specifications and advanced hands-on details. Swamp coolers typically have a five-wire application, with three different settings: low speed for the motor, high speed for the motor, and a pump setting. To wire a multi-switch to a swamp cooler, you first need to determine which wire is common, often the white one. This can be done by testing the individual settings and using a tester to identify the wires with power.

Identifying the Common Wire

To determine the common wire, you can follow these steps:

  1. Turn the switch to one of the settings that isolates an individual setting, such as vent high, vent low, or pump.
  2. Use a voltage tester to check which wires have power. The wire that has power in all the settings is the common wire, typically the white one.

How to Wire Multiswitch to Swamp Cooler

Once you have identified the common wire, you can proceed to wire the multiswitch to the swamp cooler. The wire connections are as follows:

Wire Color Connection
White Common wire
Black Hot wire for high-power setting
Red Low wire for low-power setting
Green Ground wire
Yellow Water pump wire

On the cooler side:

  1. The black wire connects to the blower motor via a junction.
  2. The white wires or neutral connect to the common junction point on the water pump and the white connection point on the switch.
  3. The green wire functions as the ground and connects to the ground points, held in place by a nut.

On the switch side:

  1. The black wire connects to the L1 terminal.
  2. The 1 terminal is for the red wire that connects to the low-power side of the blower.
  3. The 2 terminal is the connection point for the yellow wire going to the water pump power or hot terminal.
  4. The C connection is the black wire connecting to the blower for the high-power connection.

It is crucial to ensure that the black wire or hot wire is connected correctly, as it is the sensitive issue in the wiring process.
