Water timer and method

A user interface for a water timer comprising:

• a user input region comprising:
• a plurality of display areas for display of water timer status information;
• and
• a plurality of input areas for user input of water timer inputs;
• and
• all of the display areas and input areas being single-function areas and being simultaneously visible to and accessible by a user.

A user interface for a water timer comprising:

• a user input region comprising:
• a plurality of display areas for display of water timer status information, said status information comprising watering zone identifiers and watering duration indicators;
• and
• a plurality of input areas for user input of water timer inputs;
• and
• at least one of the display areas configured to display a graphical representation of the watering duration indicators for respective ones of the watering zone identifiers.

A water timer of the type comprising a user interface, a controller coupled to the user interface and programmed to provide control signals for controlling a plurality of flow control devices, each flow control device capable of controlling the passage of water from a water source to a watering zone, the improvement comprising:

• an ambient temperature sensor operably coupled to the controller to sense an ambient temperature and provide an ambient temperature signal to the controller;
• an ambient humidity sensor operably coupled to the controller to sense an ambient humidity and provide an ambient humidity signal to the controller;
• and
• the controller programmed to:
• store a base temperature and a base humidity;
• calculate an increase or a decrease in a watering amount according to any differences between the base and ambient temperatures and humidities;
• and
• modify the control signals, thereby modifying the amount of water supplied, according to said calculated differences.

A method for automatically adjusting the amount of water supplied by a water timer, the water timer of the type comprising a user interface, a controller coupled to the user interface and programmed to provide control signals for controlling a plurality of flow control devices, each flow control device capable of controlling the passage of water from a water source to a watering zone, the method comprising:

• sensing a base ambient temperature and providing a base ambient temperature signal to the controller;
• sensing a base ambient humidity and providing a base ambient humidity signal to the controller;
• subsequently sensing a current ambient temperature and providing a current ambient temperature signal to the controller;
• subsequently sensing a current ambient humidity and providing a current ambient humidity signal to the controller;
• and
• modifying control signals, thereby modifying watering amounts, according to the base and current ambient temperature signals and the base and current ambient humidity signals.
