Installation Of The Digital Controller - Daikin Altherma EDHQ011AA6V3 Installationsanleitung

The unit is designed to receive an input signal by which the unit
switches into forced off mode. At that moment, the outdoor unit
compressor will not operate.
Warnings
for a benefit kWh rate power supply like illustrated
below as type 1
If the benefit kWh rate power supply is of the type that
power supply is not interrupted, then control of the
heaters is still possible.
For the different possibilities of controlling heaters at
moments that benefit kWh rate is active, refer to
"[D] Benefit kWh rate power supply" on page 25.
If heaters must be controlled at moments that the
benefit kWh rate power supply is off, then these
heaters shall be connected to a separate power
supply.
During the period that the benefit kWh rate is active
and power supply is continuous, then stand-by power
consumption is possible (PCB, controller, pump, ...).
for a benefit kWh rate power supply like illustrated
below as types 2 or 3
Benefit kWh rate power supplies that completely shut
power supply are not allowed for this application because
of the water freeze prevention that would not be powered.

When the outdoor 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
The benefit kWh rate power supply is of the type that power supply is
not interrupted.
type 2 and 3
The benefit kWh rate power supply is of the type that power supply
will be interrupted after elapse of time or is interrupted immediately.
Benefit kWh rate power supplies that completely shut
power supply like illustrated above as types 2 and 3
are not allowed for this application because of the
water freeze prevention that would not be powered.
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
"[D] Benefit kWh rate power supply" on page 25 of
chapter "Field settings".
NOTE 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.

(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 "[3] Auto restart" on page 21.
(2) When the signal is released again, the voltage free contact will open and
