Likely problem

Solution

4 – Supply fan error Unit is not

working

Overheated fan or defect on

thermal contact of inlet fan

Determine the cause of the overheating (de

fective bearing, short-circuit...) or replace the

engine.

5 – Exhaust fan

error

Unit is not

working

Overheated fan or defect on

thermal contact of inlet fan

Determine the cause of the overheating (de

fective bearing, short-circuit...) or replace the

tilating

Clogged filter

If the unit does not have a pressure sensor for

the filter, RESET the clogged filter according to

the manual.

7 – Exhaust filter

clogged

Unit is ven

tilating

Clogged filter

Check the condition of the filter, or replace it. If

the unit does not have a pressure sensor for the

filter, RESET the clogged filter according to the

manual.

8 - Failure in pre

heating 1

Unit is ven

tilating

Preheated electric exchang

er or damaged sensor Open
