Allowed only for EDL and EBL unit models
When the unit is connected to a benefit kWh rate power supply, the
voltage free contact of the receiver controlling the benefit kWh rate
signal of the electricity company must be connected to clamps 17
and 18 of X2M (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
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to

When connecting the equipment to a benefit kWh rate
power supply, change field settings [D-01] and both [D-01]
and [D-00] in case the benefit kWh rate power supply is of
the type that power supply is not interrupted (like illustrated
above as type 1). Refer to
supply/Local shift value weather dependent" on page 35
chapter
If the benefit kWh rate power supply is of the type that
power supply is not interrupted, the unit will be forced to
off. Controlling the solar pump is still possible.
4
When the benefit kWh rate signal is sent, the centralised
control indicator e will flash to indicate that the benefit
kWh rate is active.
Installation of the digital controller
4
The unit is equipped with a digital controller offering a user-friendly
way to set up, use and maintain the unit. Before operating the
controller, follow this installation procedure.
