(default value).
only when DIP switch SS2-3 is OFF.
If [D-
01]=1 or 2, the unit is connected to a benefit kWh rate
power supply. In this case the wiring requires specific
installation like explained in "Connection to a benefit kWh
rate power supply" on page 21.
When parameter [D-
01]=1 at the moment that the benefit
kWh rate signal is sent by the electricity company, that
contact will open and the unit will go in forced off mode

.
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by [4-02] or if the
outdoor temperature drops below the value set by [F-01]. When the
pump operation is enabled, the pump operation is possible at all
outdoor temperatures. Refer to "Pump operation configuration" on
page 23.
