VAM350~2000J7VEB
Heat reclaim ventilation unit
4P487293-1A – 2018.05
Standard method
▪ A total of up to 16 air conditioners and heat reclaim ventilation units can be controlled.
▪ The ventilation mode can be operated independently when air conditioners are NOT
used.
▪ Using the local setting of the controller for air conditioners, various settings such as
precool/preheat on/off, ventilation flow rate, ventilation mode, etc. can be selected.
▪ Since all VRV units of the installation are connected to a single communication line,
they will all be operated.
▪ If there are problems operating all VRV units, do NOT use this system.
▪ Up to 64 groups of units can be controlled.
▪ The controller control transmission line can be extended to up to 1000 m.
a
▪ A direct duct connection is NOT possible.
▪ Set ON for central zone link setting.
▪ Adapter PCB for remote control: KRP2A51 (One adapter PCB should be installed in
either the heat reclaim ventilation unit or the air conditioner).
▪ The heat reclaim ventilation unit will operate ONLY when the air conditioner fan is on.
▪ Other specifications are the same as those of the standard system.
Standard method
▪ Unified ON/OFF controller: DCS301B(A)51. Up to 16 groups can be controlled (ON/
OFF) by 1 controller and up to 4 controllers can be installed in 1 system.
▪ Schedule timer: DST301B(A)51. One schedule timer can control the weekly schedule
of up to 128 units.
a
▪ Adapter PCB for remote control: KRP2A51 (NOT possible to use together with another
central controller). 1 adapter PCB can control up to 64 groups collectively.
▪ One of the controllers must be connected to an air conditioner. (However, ONLY
KRP2A51 can be connected to a heat reclaim ventilation unit.).
▪ Use of the central controller enables zone control via the central control line (up to 64
zones).
▪ Central controller DCS302C(A)51, intelligent Touch Controller DCS601C51, or
a
intelligent Touch Manager DCM601A51.
▪ A central controller can control independent operation of the heat reclaim ventilation
units in each zone.
▪ Mode number: e.g. 19(29), where 19 is the mode number for
group settings and 29 is the mode number for individual settings.
▪ Switch number: e.g. 1
▪ Position number: e.g. 02
