Initial setting for “Central zone control”<br />
When HRV unit is connected to the central transmission line (terminal connector no. (F1) and (F2)), it is necessary to make a initial<br />
setting of “collective zone interlock” by the remote controller for indoor unit. (Factory set “OFF”.)<br />
Make initial setting as follows.<br />

Cautions<br />
When you make an initial setting “ON”, the interlocked operation has a priority, and it is impossible to operate / stop HRV unit<br />
independently by the central remote controller or the unified ON / OFF controller. If there is no indoor unit for interlocked<br />
operation in the same zone, make an initial setting “OFF”.<br />
When you make an initial setting “OFF”, the independent operation of HRV unit has a priority, and the interlocked operation is<br />
not possible.<br />
When the HRV unit is operated independently by the central controller, the HRV unit will not operate until the preset time elapses<br />
if the precool / preheat time setting is set. Therefore, please do not set the precool / preheat time setting in normal operation.<br />
Example of system<br />
Central<br />
remote<br />
controller<br />
Unified ON / OFF<br />
Controller<br />
The unit 1<br />
The operation and display by the central<br />
controller will be basically the same as those on<br />
the remote controller for indoor unit. However,<br />
the HRV unit cannot be operated independently<br />
by the central controller.<br />
The unit 2<br />
The operation of HRV unit is interlocked with<br />
indoor units in the same zone, and the HRV unit<br />
can also be operated independently by the<br />
central remote controller. However, it can not be<br />
operated independently by the unified ON / OFF<br />
controller.<br />
The unit 5<br />
When the central remote controller is used, each<br />
unit will be one zone, unless you set the zone for<br />
plural units.<br />
