6 of X3M (as illustrated in the figure above).
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 parameter [D-01]=2 at the moment that the benefit kWh rate
signal is sent by the electricity company, that contact will close and
the unit will go in forced off mode
Type 1
This type of benefit kWh rate power supply is not interrupted.
Type 2
This type of benefit kWh rate power supply is interrupted after elapse
of time.
Type 3
This type of benefit kWh rate power supply is interrupted immediately.
(1) When the signal is released again, the voltage free contact will close and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to
(2) When the signal is released again, the voltage free contact will open and
