Whenever the compressor shuts off, system pressures must be allowed
to equalize. At this time, an internal timer begins a count-down from up to
240 seconds. If a demand for heat or cool occurs during this count-down

operate until the count-down has completed. This timer prevents damage
to the unit if it tries to start too quickly after it stops running. Normally the

by this timer.
