Independent System - Daikin VAM350J7VEB Installer And User Reference Manual

NOTICE
If you change the ducting, then install clean filters and
reconfigure setting 19(29)‑0‑04 or 19(29)‑0‑05, otherwise
the signal to clean the filters will come too soon. Do NOT
adjust the dampers when setting 19(29)‑0‑04 or 05 is
activated.
▪ If the user interface is switched off while you are activating setting
19(29)‑0‑04 or 19(29)‑0‑05, the configuration is aborted. When
you switch the user interface back on, the function starts from the
beginning.
▪ Setting 19(29)‑0‑04 takes between 1 and 6 minutes to complete.
You can check if the setting was completed successfully by
checking if the field setting is changed to 0‑01.
▪ Setting 19(29)‑0‑05 takes between 3 and 35 minutes to complete.
You can check if the setting was completed successfully by
checking if the field setting is changed to 0‑02.
NOTICE
While activating setting 19(29)‑0‑04 and 19(29)‑0‑05, the
unit is set to heat recovery and the fan is on high or ultra
high. After the configuration, the unit is set back to what it
was before the configuration.
▪ You can ONLY activate these settings with clean filters.
▪ For VAM1500+VAM2000, make sure that the ducting pressure
drop of the top and bottom units is balanced.
▪ The function starts as soon as it is selected and the user interface
is on.
▪ Setting 19(29)‑0‑04 CANNOT be configured if the outside
temperature is ≤–10°C, which is out of the operation range.
▪ Setting 19(29)‑0‑05 CANNOT be configured if the outside
temperature is ≤5°C. In this case error 65‑03 is shown and the unit
stops working. Change the setting to 19(29)‑0‑04.
▪ The setting CANNOT be configured if there are alerts or errors
present.
▪ If booster fans are used, you can ONLY configure setting
19(29)‑0‑03.
▪ You can configure settings 19(29)‑0‑04 and 19(29)‑0‑05 for
multiple units with 1 user interface.

NOTICE
Factory settings: Do NOT change the switch settings when
a user interface is connected. SS1 is a setting switch to
operate without user interface. Changing the settings when
a user interface is connected, will stop the unit from
operating normally. Keep the switch on the PCB at the
factory setting.

8.3.3 1-group linked-control system
▪ You can use the air conditioner's user interface to control up to 16
units, a combination of indoor air conditioner units and heat
reclaim ventilation units.
▪ You can configure initial settings for the functions of the heat
reclaim ventilation units. These functions are pre-cool/pre-heat,
ventilation air flow, ventilation mode, and fresh-up. Use the air
conditioner's user interface to configure the initial settings for the
heat reclaim ventilation units. See
page 24.

8.3.4 Linked control with more than 2 groups
To change the settings, P1/P2 MUST be connected to the heat
reclaim ventilation units. That means that you have to connect a user
interface to the unit. You can remove the user interface after you
have changed the settings.
If the unit is supposed to operate without user interface, do NOT
switch it on with the user interface connected. Otherwise, the unit will
give an error once the controller is removed, because it will keep on
searching for the user interface signal. To resolve the error, perform
a power reset without the user interface connected.
▪ You need the optional adapter printed circuit board (KRP2A51)
connected to 1 unit that is part of the F1/F2 loop. The unit can be
an indoor unit or a heat reclaim ventilation unit.
▪ You can connect up to 64 units, a combination of air conditioners
and heat reclaim ventilation units, to the F1 and F2 terminals.
▪ KRP2A51 ONLY has ON/OFF control. If the heat reclaim
ventilation units run in automatic mode, they have a fixed set
point. If P1/P2 is NOT connected, the set point of the indoor unit is
unknown.
▪ Use the air conditioner's user interface to configure the initial
settings.
