46 6.4 Setting Group No. for Centralized Control
Fundamental of DIII-NET
Initial setting for “Central zone control”
When HRV unit is connected to the central transmission line (terminal connector no. (F1) and (F2)), it is necessary to make a initial
setting of “collective zone interlock” by the remote controller for indoor unit. (Factory set “OFF”.)
Make initial setting as follows.

Cautions
When you make an initial setting “ON”, the interlocked operation has a priority, and it is impossible to operate / stop HRV unit
independently by the central remote controller or the unified ON / OFF controller. If there is no indoor unit for interlocked
operation in the same zone, make an initial setting “OFF”.
When you make an initial setting “OFF”, the independent operation of HRV unit has a priority, and the interlocked operation is
not possible.
When the HRV unit is operated independently by the central controller, the HRV unit will not operate until the preset time elapses
if the precool / preheat time setting is set. Therefore, please do not set the precool / preheat time setting in normal operation.

The unit
The operation and display by the central
controller will be basically the same as those on
the remote controller for indoor unit. However,
the HRV unit cannot be operated independently
by the central controller.
The unit
The operation of HRV unit is interlocked with
indoor units in the same zone, and the HRV unit
can also be operated independently by the
central remote controller. However, it can not be
operated independently by the unified ON / OFF
controller.
The unit
When the central remote controller is used, each
unit will be one zone, unless you set the zone for
plural units.
