Fresh-up operation by external input [HRV unit]
Purposes and functions
When the operation is interlocked with the local ventilating fan
(such as the one for toilet or kitchen), the HRV unit performs the
over-supply operation to prevent the reverse flow of the odor.
The flow rate of supply air becomes higher than that of exhaust
air.
