9.9.9 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 inflow of the odor from outside.
The flow rate of supply air becomes higher than that of exhaust air.
Both the excessive supply mode (Supply Fresh-up) and the excessive exhaust mode (Exhaust Fresh-up)
are selectable.
In details, contact your dealer.
EXAMPLE OF CONTROL WIRING
Connecting line can be extended up to 50m maximum.
