An electronic system for controlling an evaporative cooler (101) away from the location of a wall-mounted control switch (301). A remotely triggered high/low module (302) is installed in a roof-mounted electrical disconnect box (114). The existing wall-mounted manually operated control switch (117) is replaced with a new control switch (301) which contains a pump selection switch (304), a fan motor selection switch (305), and a remotely triggered on/off module (303). A variety of remote control devices can then be used to control the evaporative cooler (101), such as a PLC time-clock (501), an RF keychain remote (601) and PLC transceiver (701), a PLC thermostat (801), a PLC setback thermostat (901), a PLC telephone transponder (1001), or a computer interface (1101).

1. A system for controlling the operation of an evaporative cooler of the type having a plurality of cooler pads, a cooling liquid reservoir, a pump having a motor for circulating cooling liquid from said reservoir onto said cooler pads, a blower fan having a motor with a plurality of speeds for drawing outside air through said cooler pads and for discharging it into an air duct distribution system, an electrical disconnect, a control switch, and wires connecting a main power source with said electrical disconnect and said control switch, said system comprising:a. a control device selected from the group consisting of thermostats, time clocks, manual switches, occupancy sensors, telephone transponders, and computer interfaces, b. a signal transmitter for transmitting a signal using a technology selected from the group consisting of power line carrier, radio frequency, radar, infrared, visible light, laser, and ultrasonic, c. a receiver for said signal, d. a switching device for coupling and uncoupling said motors of said pump and said fan from said power source, e. a switching device for changing speeds of said fan motor, whereby a signal from said control device can be transmitted from a multitude of locations and received by said switching devices thereby energizing, de-energizing, and changing speeds of said fan and pump motors and no additional wires are required.
