Operation Manual
2.8. Troubleshooting
If the unit is inoperative:
•
Make sure the feeding cable is plugged into an electrical outlet.
•
Check all safety fuses of the automatic control block. In case of need, replace the faulty fuses with the new
ones of the same electric parameters (fuses parameters are in wiring diagram).
• Make sure there is no failure message in the control panel. If there is a problem, you must first remove it.
To remove the problem, follow the table 2.8 describing failures.
•
If nothing is shown on the control panel, check the cable that connects the remote panel to the unit.
If air flow is reduced:
•
Check set ventilation intensity level (see chapter 2.5.).
• Check air filters‘ condition. If needed, replace with the new ones.
•
Check supply/exhaust air diffusers adjustment.
•
Check for clogging outside air intake grille.
•
Check if system ducting is not damaged and there are no extraneous things inside.
If supplied air is too cold:
•
Check temperature setting (see chapter 2.5.).
•
Check if „Winter“ mode is set on the panel.
•
Check if there is no failure indication on the control panel (see table 2.8.).
•
Check fuse F2 located on the automatic box.
If the unit has been stopped and there is red light diode signal on the controller,
and text message is shown meaning failure, failure needs to be eliminated!
Before starting any operations inside the unit, make sure that the unit is
switched off and the power supply voltage is shut off.
After failure has been eliminated and power supply connected, text message appears about previous failure. If
there are no more failures, unit is switched on by pressing
button; unit continues operating by preset mode.
However if the failure has not been eliminated, unit either starts operating and after some time it stops again, or it
does not operate and failure message is indicated.
