Initial settings
Activate below setting for direct duct connection. This direct duct
configuration ONLY works if P1/P2 is connected.
▪ Mode number: 17
▪ Switch number: 5
▪ Position number: 02
Other functions
As in 1-group linked-control system, you can also configure other
heat reclaim ventilation unit functions.
8.3.6 Centralised control system
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.

e On/Off signal
If you use the adapter printed circuit board (KRP2A51) or schedule
timer (DST301B51), the following is valid:
▪ You can connect up to 64 units, a combination of air conditioners
and heat reclaim ventilation units, to the F1 and F2 terminals.
▪ This system does NOT require group number setting for
centralised control (auto-address system). The centralised group
number is automatically assigned if the adapter printed circuit
board (KRP2A51) or schedule timer (DST301B51) is connected.
▪ The adapter printed circuit board and the schedule timer CANNOT
be used together. The adapter printed circuit board allows on/off
control. The schedule timer allows on/off control with a weekly
schedule.
▪ You can connect the adapter printed circuit board to the electric
component mounting base of either the heat reclaim ventilation
unit or the air conditioner.
