Ozone sanitizing system

A machine implemented method of controlling an ozone sanitizing system comprising the steps of:

• generating ozone in an enclosed space using an ozone generator until a current ozone concentration in the enclosed space is within a predetermined range, or until the ozone generator has operated for a predetermined maximum time;
• repeating the generation step to maintain the current ozone concentration within the predetermined range for a predetermined cycle time, and;
• operating an ozone converter after the predetermined cycle time has passed to convert ozone in the enclosed space into oxygen until the current ozone concentration is reduced to a predetermined minimum concentration;
• wherein the ozone generator and ozone converter are controlled by a controller that is responsive to a timer and an ozone sensor in fluid communication with the enclosed space, and;
• wherein an outlet of the ozone generator and an inlet of the ozone converter are in fluid communication with the enclosed space.

A machine implemented method of maintaining a sanitizing system comprising the steps of:

• using a maintenance device to access one or more parameters for controlling the operation of an ozone sanitizing system having an ozone generator, an ozone converter, an ozone sensor, a timer, and a controller which includes a memory;
• changing one or more parameters using the maintenance device, and;
• using the maintenance device to save the parameters in the memory;
• wherein the controller is responsive to the ozone sensor and the timer and the controller controls the ozone generator and the ozone converter.
