10-8 Initial setting
10-8-3 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 control 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 control or the unified On / Off control. 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 control, 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
1
The operation and display by the central control
will be basically the same as those on the remote
control for indoor unit. However, the HRV unit
cannot be operated independently by the central
control.
The unit 2
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 control, However, it can not be
operated independently by the unified On / Off
control.
The unit
5
When the central remote control is used, each
unit will be one zone, unless you set the zone for
plural units.
