play of the number of minutes left on the timer (value is rounded up: 2 min.
1 sec. is displayed as 3). If activated, the anti-short cycle delay time remain
ing is displayed (default is 300 sec./5 min.).
Cooling Cycle
: Shows current percentage of maximum cooling
capacity. Example to the right indicates a cooling demand of 50
percent and a outdoor fan speed of 700 RPM.
The demand percentage is displayed first, followed by a pause, then the
outdoor fan speed and the ambient temperature.

Heating Pump Cycle
: Shows current percentage of maximum
heating capacity. Example to the right indicates a heating de
mand of 33 percent and an outdoor fan speed of 600 RPM.
Following string is repeated if heat pump is active with outdoor fan speed
set at 600 RPM. Note -
