5. SETTING UP THE UNIT
When powered ON, the FIN-6MD performs a 30-second booting sequence followed by a 30-minute period
where is stays OFF, but will activate if a heating or cooling call is sent to the AHU.
Refer to local building codes to determine the required airflow.
1.
Doublecheck the wiring, and turn power back ON to the AHU.
2.
Set the thermostat to send a heating or cooling call, or jump R and Y on the terminal block. This will
force the ventilation ON for at least 5 minutes.
3.
Measure the airflow.
If it needs adjustment, perform steps 4. If the airflow does not need adjustment, go to step 5.
4.
The damper is factory set to fully open position. To adjust it, set the left pot to DAMPER
ADJUSTMENT to start the AHU blower, and wait 5 seconds. The LED will blink continuously to
indicate the unit is in DAMPER ADJUSTMENT mode.
While measuring the airflow, adjust the damper using the RUN TIME % pot until you've reached the
desired value.

5.
Select the desired mode according to the table and map in section 7.3. Doing so also saves the
damper adjustment made in the previous step if applicable.
6.
Set the RUN TIME % pot.

7.
Install the supplied cover to protect the adjustment pots and
prevent an accidental change of settings. Note that the hole may
be hidden by the label.
6. TESTING

Should the air inside your house become too humid, or if such conditions want to be prevented, the operation
mode of your FIN-6MD can be changed from a Code-Compliant one (modes 1 and 2) to a Comfort Mode
(modes A to E). Refer to the map below to make the right choice.
When making such change, make sure to only change the Mode and to leave the Run time % as it was set by
