Relocation Of The Digital Controller - Daikin EKHBH054BA Manuel D'installation

When connecting the equipment to a benefit kWh rate
power supply, change field setting [D-01]. In case the
benefit kWh rate power supply is of the type that power
supply is not interrupted (like illustrated above as type 1)
change both field settings [D-01] and [D-00]. Refer to
"[D] Benefit kWh rate power supply/Local shift value
weather dependent" on page 33 of chapter "Field settings".
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.
When the benefit kWh rate signal is sent, the centralised
control indicator e will flash to indicate that the benefit
kWh rate is active.
