Total Heat Exchanger

HRV (Heat Reclaim Ventilation)

4P415946-1 – 2015.08

Fresh-up operation

Purposes

When combined with a local ventilating fan (such as the one in toilet
and kitchen), the air flow rate of HRV is balanced by either fan
operation or exhaust operation.

However, a circuit with voltage and low current (16 V, 10 mA) is
formed between JC and J1, so a relay with low-load contact point
must be used.

Functions

The unit performs overcharged operation to prevent back flow of
odour.

Necessary parts

Operation contact of exhaust ventilating fan (Field supply)

RUN

After completing the installation of the system, check again to make
sure that No error was made in wiring or switch setting on the printed
circuit boards of the HRV units.

Then, turn on the power of the HRV units. Refer to the manual of the
remote controller of each unit (remote controller for air conditioner,
central control unit, etc.) for conducting a trial operation.
