▪ 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 VAM 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

NOTICE
Group control connection is NOT allowed with EKVDX indoor units.
To change the settings, P1/P2 of the controller MUST be connected to the VAM
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 VAM unit.
