Abstract
An integrated electronic control arrangement is disclosed in the illustrative environment of a gas-fired furnace. The control incororates a self-test feature which shuts down the furnace and displays a diagnostic fault code in the event of any one of a number of possible sensed faults. Self-testing occurs automatically before an attempt at ignition and during furnace operation. The self-test may also be initiated manually at any time the furnace is not operating. The control accepts digital information on daily temperature setback, weekend temperature setback and vacation setback in any one of several preset schedules and preset setback increments. The control has a multipurpose display for selectively showing component indicative failure codes, temperature setback schedules, time of day, and day of the week.
