Abstract
The system comprises an electronic timer circuit in a housing. The system having an automatic voltage sensor, a handheld tool, and a tool storage location. The sensor eliminates the need for manual voltage selection. The handheld tool connects to the circuit via a USB cable and is storable about the housing. The tool processes data it receives from the circuit and displays various information to a user.

A timer for a cooling appliance, the timer comprising:
- a timer circuit;
- the timer circuit being attachable and detachable to an appliance via a terminal block;
- the timer circuit having a connection port;
- a cable;
- a tool;
- the tool being attachable and detachable to the timer circuit via the connection port and the cable;
- the tool capable of processing electronic information that is digitally stored on the timer circuit;
- the tool presents data derived from the processed electronic information to a user;
- a sensor;
- the sensor having a plurality of controls;
- the sensor being attached to the timer circuit;
- the sensor being configured to automatically determine a value of a voltage that is supplied to the timer circuit from an external power source and adjust the timer circuit to accommodate the voltage.
A method of using a portable timer for a cooling appliance and a handheld reader unit to troubleshoot defrost cycle operations, the timer including a timer circuit that is attachable and detachable to the cooling appliance, the timer further including a connection port and a cable, a handheld reader unit being attachable and detachable to the timer circuit via the connection port and the cable, the handheld reader unit processing electronic information from the timer circuit and presenting data to a user, a sensor having a plurality of controls and the sensor being attached to the timer circuit and capable of automatically sensing and adjusting for different voltage levels supplied to the timer circuit, the method comprising:
- a first step of a user encountering an inventive timer;
- next locating the timer and review it for indications of error messages;
- then if the user determines that no troubleshooting is necessary, then making repairs or adjustments to the cooling appliance, however if an error is indicated then a handheld reader is removed by the user from a storage location within the timer's housing;
- next, the technician uses a cable and connects the handheld reader to the timer;
- next the “timer” button is pressed which causes the timer to communicate with the handheld unit, electronic data that was stored on the timer's circuitry is now available for viewing on display of the handheld unit;
- then the technician will scroll through data that is presented on the display of the handheld reader and choose a record of interest and analyze the defrost cycle data related to the operation of the cooling appliance;
- next the technician determines the proper repairs or adjustments needed and completes the job.
A method of using a portable timer for a cooling appliance and a handheld reader unit to troubleshoot defrost cycle operations, the timer including a timer circuit that is attachable and detachable to the cooling appliance, the timer further including a connection port and a cable, a handheld reader unit being attachable and detachable to the timer circuit via the connection port and the cable, the handheld reader unit processing electronic information from the timer circuit and presenting data to a user, a sensor having a plurality of controls and the sensor being attached to the timer circuit and capable of automatically sensing and adjusting for different voltage levels supplied to the timer circuit, the method comprising:
- encountering the cooling appliance including an inventive timer;
- locating the timer and reviewing for error indications;
- in response to an absence of error indications indicating no need for troubleshooting, making repairs and/or adjustments to the cooling appliance;
- in response to an error indication being present, troubleshooting the cooling appliance by:
- removing a handheld reader from a storage location within the timer housing;
- connecting the handheld reader to the timer with a cable;
- initiating communication between the timer and the handheld unit to enable historical records from the timer to be read from the handheld unit;
- identify a relevant historical record;
- and
- determine appropriate repairs and/or adjustments in accordance with the relevant historical record.
