INSTALLER’S TROUBLESHOOTING (CONT’D)

ERROR

DESCRIPTION

SOLUTION

E26

Supply motor (drive over temp)

STEP  1:  Validate  if  the  air  exchanger  is  exposed  to  ambient  temperatures  within  the

operating limits 

(LOCATING AND MOUNTING THE UNIT on p4)

If STEP 1 did not fix the problem, perform STEP 2: Replace the electronic assembly.

E32

Exhaust airflow

STEP  1:  Perform  a  visual  inspection  of  the  exhaust  damper  system.  Clean  filters,

distribution registers and outside supply hood. Inspect ducting to ensure it is not squeezed

or bent.
If STEP 1 did not fix 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 flow. If so,

review the ducting path.
If STEP 2 did not fix the problem, perform STEP 3: On the LCD screen, select the MIN and

MAX flow setting values then  reset the unit. MAX flow value will display on  the LCD

screen. If MAX flow is above desired MAX flow, set MAX and MIN flows.
If STEP 3 did not fix the problem, perform STEP 4: Replace the exhaust blower and repeat

STEP 3.
If STEP 4 did not fix the problem, perform STEP 5: Replace the electronic assembly.

E33

Exhaust motor (drive over current)

STEP 1: Unplug/plug unit.
If STEP 1 did not fix the problem, perform STEP 2: Remove core and clear the ventilation

wheel from any dirt or obstacles.
If STEP 2 did not fix the problem, perform STEP 3: Disconnect J3 (red) and connect a spare

blower  system.  If  it  works,  replace  exhaust  blower.  If  STEP  3  did  not  fix  the  problem,

perform STEP 4: Replace the electronic assembly.

E37

Exhaust motor (drive foc duration)

E38

Exhaust motor (drive speed feedback)

E39

Exhaust motor (startup)

E34

Exhaust motor (drive over voltage)

STEP 1: Unplug/plug unit. Under and over voltage may be detected with severe in-house

power  supply  fluctuation  and  stop  the  motor  for  protection.  If  STEP  1  did  not  fix  the

problem, perform STEP 2: Replace the electronic assembly.

E35

Exhaust motor (drive under voltage)

E36

Exhaust motor (drive over temp)

STEP  1:  Validate  if  the  air  exchanger  is  exposed  to  ambient  temperatures  within  the

operating limits 

(LOCATING AND MOUNTING THE UNIT on p4)

If STEP 1 did not fix the problem, perform STEP 2: Replace the electronic assembly.

E40

Outside air thermistor

STEP 1: Check if thermistor is well connected in connector J7A.
If STEP 1 did not fix the problem, perform STEP 2: Disconnect connector J7A and check if

the measured resistance (thermistor connector) is within 5 Kohms to 120 Kohms. If outside

the range, replace the thermistor.
If STEP 2 did not fix the problem, perform STEP 3: Replace the electronic assembly.

E41

Distribution air thermistor

STEP 1: Check if thermistor is well connected in connector J7B.
If STEP 1 did not fix the problem, perform STEP 2: Disconnect connector J7B and check if

the measured resistance (thermistor connector) is within 5 Kohms to 120 Kohms. If outside

the range, replace the thermistor.
If STEP 2 did not fix the problem, perform STEP 3: Replace the electronic assembly.

E42

PCBA thermistor fault

STEP 1: Replace the electronic assembly.

E43

PCBA temperature over limit

STEP  1:  Validate  if  the  air  exchanger  is  exposed  to  ambient  temperatures  within  the

operating limits 

(LOCATING AND MOUNTING THE UNIT on p4)

If STEP 1 did not fix the problem, perform STEP 2: Replace the electronic assembly.

E50

Wall control communication lost

STEP 1: Unplug unit, inspect wires, plug unit.
If STEP 1 did not fix the problem, perform STEP 2: Remove wall control from the wall

installation and test with a short cable. If it works, bring a new cable to the wall installation

location.
If STEP 2 did not fix the problem, perform STEP 3: Test the air exchanger with a spare wall

control. If it works, replace the wall control.
If STEP 3 did not fix the problem, perform STEP 4: Replace the electronic assembly.

E51

Wall control sensor

STEP 1: Unplug unit, inspect wires, plug unit.
If STEP 1 did not fix the problem, perform STEP 2: Replace the wall control.

E60

Protection mode

STEP 1: Perform general inspection of the unit (dampers, core, filters).
