7.4.4 Precool / Preheat Operation
Purposes and
Functions „ The operation of HRV unit is delayed when the air conditioner begins operation.
Cautions: 1. The precool / preheat function is possible only when the operation of HRV unit is interlocked
to one-group or two-group of indoor unit.
(It will not function when the HRV unit is in independent operation.)
2. You can select the preset time of 30 / 45 / 60 minutes for delayed operation at the time of
initial setting.
If this preset time is not sufficient, you can extend the preset time for further 30 / 60 / 90
minutes only the preheating function.
3. Since this is two remote controller system (for Indoor unit and HRV unit), the Master / Slave
setting is required.
