VAM-HVE/HVLT Series
Interlocking control of 2 or more groups
Purpose • Function
Performs energy-saving interlocked control with 2 or more groups of commercial multi air conditioners (multi for buildings)/SkyAir.
Heat Reclaim Ventilator Unit also operates if any of the air conditioners is in operation.
During intermediate periods, independent operation of Heat Reclaim Ventilator Unit can be performed.
POINT
No group number needs to be set for centralized control.
Wiring adapter for electrical appendices (KRP2A Series) is incorporated in one of the units connected by a centralized transmission
line.
(Please check the applicable models of adapter printed circuit board.)
Direct duct connection is not allowed.
When a central remote controller is connected, wiring adapter for electrical appendices is not required. (See page 36)
Since zone interlock setting is made on the Heat Reclaim Ventilator Unit, a remote controller needs be connected to Heat Reclaim
Ventilator Unit as well.
Connect a remote controller to (P1) and (P2) terminals to make the setting.
When the units are to be used without remote controller, remove the remote controller connected after the installation.
