1. A wireless, programmable controller system to control and operate a paired evaporative cooler, said controller system comprises:

  • a main controller unit, used inside a building, to control the building inside temperature and the building inside humidity by operating and controlling a paired evaporative cooler, said main controller unit is programmable in response to input data received which are;

    outside measured humidity, outside measured temperature and outside barometric pressure, and said main controller unit is programmable according to a plurality of programming modes to generate digital control data to be sent to the paired evaporative cooler to cause a control of variations of a paired evaporative cooler fan'"'"'s speed and variations of a paired evaporative cooler water pump speed;

    a remote sensor unit, operating outside the building, said remote sensor unit is battery-powered, operated by a programmed internal microprocessor to collect outside temperature, outside humidity and outside barometric pressure digital reading data, to be transmitted over a wireless communication medium via a radio frequency transceiver to said main controller unit;

    said remote sensor unit is radio frequency-coupled to said main controller unit.
