About setting 19(29)-0-04 and 19(29)-0-05

▪ When you have configured setting 19(29)‑0‑04 successfully, the
system automatically changes it to setting 19(29)‑0‑01.
▪ When you have configured setting 19(29)‑0‑05 successfully, the
system automatically changes it to setting 19(29)‑0‑02.
NOTICE
If the ducting is changed, 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 controller is switched off while activating setting 19(29)‑0‑04
or 19(29)‑0‑05, configuration is aborted. When you switch the
controller 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.
INFORMATION
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 configuration, the settings are returned to what
they were before the configuration.
▪ These settings can ONLY be activated with clean filters.
▪ For models 1500+2000, 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 controller 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.
▪ Settings 19(29)‑0‑04 and 19(29)‑0‑05 can be configured for
multiple units with 1 controller.

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

1-group linked-control system

▪ The air conditioner's controller can be used 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 precool/preheat,
ventilation air flow, ventilation mode, and fresh-up. Use the air
conditioner's controller to configure the initial settings for the heat
reclaim ventilation units. See

Linked control with more than 2 groups

To change the settings, P1/P2 of the controller MUST be connected
to the heat reclaim ventilation units. The controller can be removed
after the settings are changed.
If the unit is supposed to operate without controller, do NOT switch it
on with the controller connected. Otherwise, the unit will give an
error once the controller is removed, because it will keep on
searching for the controller signal. To resolve the error, perform a
power reset without the controller connected.
▪ The optional adapter PCB (KRP2A51) must be connected to 1 unit
that is part of the F1/F2 loop. This unit can be an air conditioner or
a heat reclaim ventilation unit.
▪ Up to 64 units, a combination of air conditioners and heat reclaim
ventilation units, can be connected 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 setpoint.
If P1/P2 is NOT connected, the setpoint of the air conditioner is
unknown.
▪ Use the air conditioner's controller to configure the initial settings.
