Turning Back the Clock
Beginning in 2007, however, most of the U.S. will begin daylight-saving time at 2 a.m. on the second Sunday in March and end on the first Sunday in November.
Service equipment that is preprogrammed with daylight-saving times may need to be manually changed twice - once in the spring and once in the fall. The first time because of the new dates and the second time because the program will automatically change again and will need to be corrected.
In some equipment there is no way to update the memory to fix this problem permanently, and equipment replacement might be the only solution.
Options VI Inc. recommends that contractors update their maintenance task schedules and include this specific task to all service agreements to ensure that these control systems don’t get overlooked.
