<Symptom>

The fans rotates after 1 minutes when pressing on on/off but-
ton.

<Cause>

This indicates that the operation is in preparation.
Wait for about 1 minute.

• Operation stops sometimes.

<Symptom>

“U5” is displayed on the remote controller and the operation 
stops but then restarts after a few minutes.

<Cause>

This indicates that the remote controller is intercepting noise 
from electrical appliances other than the HRV unit, and this 
prevents communication between the units, causing them to 
stop.
Operation automatically restarts when the noise goes away.

• “88” is displayed on the remote controller.

<Symptom>

It displays immediately after the power is turned on, and dis-
appears after several seconds.

<Cause>

This indicates that the unit is checking whether or not the 
remote controller is normal.
It is only displayed temporarily.

5.2 IF ONE OF THE FOLLOWING MALFUNCTIONS 

OCCURS, TAKE THE MEASURES SHOWN 
BELOW AND CONTACT YOUR DAIKIN DEALER

The system must be repaired by a qualified service person.
DO NOT CHECK AND REPAIR OPENING INSIDE THE UNIT 
BY YOURSELF.

WARNING

When the HRV is in abnormal conditions (smell of some-
thing burning, etc), cut off the power, and contact your 
dealer.

Continued operation under such circumstances may result in a 
failure, electric shock, and fire.

The unit does not operate at all.

a. Check if there is a power failure.

Measure:

After power has been restored, start operation 
again.

b. Check if the fuse has blown.

Measure:

Turn the power off.

c. Check if breaker has worked.

Measure:

Turn the power on with the 
breaker switch in the off 
position.
Do not turn the power on 
with the breaker switch in 
the trip position.
(Contact your dealer.)

If a safety device such as a fuse, a breaker, or an earth 
leakage breaker frequency actuates, or ON/OFF switch 
does not properly work.
Measure:

 Do not turn the power on.

The remote control buttons do not work well.
Measure:

 Turn off the main power switch.

• If the display “

” (INSPECTION), “UNIT No.” and the 

OPERATION lamp flash and the “MALFUNCTION
