rate. However, a limiting feature will not allow more than 6
equipment cycles per hour, regardless of setting. Values can range
from 1 to 9. Factory default setting is 3. This default selection will
provide optimum performance in nearly all installations. Try it
first. Do not change setting unless there is evidence of need to do
so.
Unlike conventional anticipators, this setting is not to be deter-
mined by current draw. There is no need to measure, know, or
compensate for current. There is also no droop with this thermo-
stat, regardless of anticipator setting. This adjustment controls only
sensitivity and cycle rate up to the maximum of 6 cycles per hr.
