Supply airow
STEP 1: Unplug the unit. 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. Plug the unit.
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.
W32
Exhaust airow
STEP 1: Unplug the unit. Perform a visual inspection of the exhaust damper system. Clean
lters, distribution registers and outside exhaust hood. Make sure no non-return damper
is installed in exhaust hood since it can freeze in winter. Inspect ducting to ensure it is not
squeezed or bent. Plug the unit.
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 exhaust blower and repeat
STEP 3.
If STEP 4 did not x the problem, perform STEP 5: Replace the electronic assembly.

STEP 1: Press + or - to access the selection menu.
STEP 2: Complete conguration. (Refer to section 5 for more details).

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 airows 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
airow and generate vibrations and noise in the unit.
CAUTION
NOTE: 210 and 230 CFM models have a cooling fan in electrical box that can start if ambient temperature near the unit is
over 40°C (104°F).
180 CFM ERV Models
The unit will reduce airow by 30 CFM if the max airow during auto-balancing procedure is 130 CFM or less to prevent
ERV core membrane deformation due to very high static pressure (over 1.3 in. w.g.).
All 180 CFM Models
Error E22 or E32 will display if the maximum airow is 90 CFM or less during the auto-balancing procedure (the unit
will attempt to execute auto-balancing procedure 3 times before displaying an error). Static pressure of ducting shall be
reduced to allow good operation of the unit.
210 CFM ERV Models
The unit will reduce airow by 30 CFM if the max airow during auto-balancing procedure is 160 CFM or less to prevent
ERV core membrane deformation due to very high static pressure (over 1.3 in. w.g.).
All 210 and 230 CFM Models
Error E22 or E32 will display if the maximum airow is 120 CFM or less during the auto-balancing procedure (the unit
will attempt to execute auto-balancing procedure 3 times before displaying an error). Static pressure of ducting shall be
reduced to allow good operation of the unit.
