A. ANTICIPATOR -- Value Adjustment
This adjustment controls the sensitivity and cycle rate of the thermostst. Higher numbers decrease the sensitivity and slow the cycle rate. Lower numbers increase the sensitivity and increase the cycle rate. However, a limiting feature will not allow more than 4 equipment cycles per hour, regardless of setting. Values can range from 1 to 3. Factory default setting is 2. This default selection will provide optimum performance in nearly all installations. Try it first. Do not change settings unless there is evidence of need to do so. Unlike conventional anticipators, this setting is not determined by current draw.
