Warning deSCription Solution
W22
Supply airow
STEP 1: Perform a visual inspection of the supply damper system. Clean lters, distribution
registers and outside supply hood. Inspect ducting to ensure it is not squeezed or bent.
If STEP 1 did not x the problem, perform STEP 2: Remove ducting of the supply path. On the
LCD screen, select MAX to check if the unit is able to reach the selected ow. If so, review the
ducting path.
If STEP 2 did not x the problem, perform STEP 3: On the LCD screen, select the MIN and
MAX ow setting values then reset the unit. MAX ow value will display on the LCD screen. If
MAX ow is above desired MAX ow, set MAX and MIN ows.
If STEP 3 did not x the problem, perform STEP 4: Replace the supply blower and repeat
STEP 3.
If STEP 4 did not x the problem, perform STEP 5: Replace the electronic assembly.

Exhaust airow
STEP 1: Perform a visual inspection of the exhaust damper system. Clean lters, distribution
registers and outside supply hood. Inspect ducting to ensure it is not squeezed or bent.
If STEP 1 did not x the problem, perform STEP 2: Remove ducting of the supply path. On the
LCD screen, select MAX to check if the unit is able to reach the selected ow. If so, review the
ducting path.
If STEP 2 did not x the problem, perform STEP 3: On the LCD screen, select the MIN and

W61
Protection mode
electronics
overheating
The unit is currently in protection mode. The power transmitted to the motor is deliberately
reduced to decrease electronics temperature. The unit will exit this mode by itself once
conditions are back to normal. It is normal to observe reduction in airows during this period.
This condition should appear only when the unit is set in high speed and located in a warmer
environment, for example over 30°C (86°F).
8. INSTALLER’S TROUBLESHOOTING (Cont’d)
Make sure that no piece of mineral wool will enter in the unit during installation. Otherwise, this could reduce
airow and generate vibrations and noise in the unit.
