The activation and deactivation of an outdoors, hose faucet-mounted valve unit to control the flow of water through a standard garden hose with attached sprinkler is remotely controlled from indoors rather than at the valve unit. This is accomplished without the use of unwieldy and unsightly electrical cables by means of radio frequency (RF) signals. A remote, programmable, controller unit located indoors with attached transmitting unit commands such transmitting unit to send signals in accordance with preprogrammed instructions in the controller unit. A receiver unit attached to the valve unit intercepts the transmitted signals and instructs the valve unit to open or close the water valve and flow of water based thereon. Direct connection of the controller to the valve unit is possible such that the transmitter unit and receiver unit are not used such as during pleasant weather conditions. A hand held transmitter unit can be used in place of the separate controller and transmitter to automatically control the valve unit for specific watering durations.
