In the event of change over between winter
and summer operation and vice versa, there
is a certain delay to prevent constant
starting and stopping of the compressor
when the outdoor temperature oscillates
around the temperature limit.
Below the direct start limit, the control unit
changes over to winter operation without
delay.
Circuit 1 is never allowed to switch over to
summer operation for as long as any circuit
is in winter operation.
