FROM THE SYNOPTIC, IN “SET BUS VALUES”:
Remarks
- Test the compensation valve opening,
Test airflow when the compensation is opened and no airflow when
the compensation valve is closed.
Measure compensation valve airflow under 60Pa, must be more
than 150m
3
/h
- Test the HUB dampers opening, pipe by pipe.
Test airflow when the pipe damper is opened and no airflow when
the compensation valve is closed.
1.Test the preheater functioning (if preheater).
If preheater, start à 100% preheater warming and check the Tean
T° increases (to be allowed to warm, supply airflow must be more
than 50m
3
/h)
Set then the PWM of the preheater to 100%
Wait some minutes until the incoming air temperature (TEAN) begins to increase.
Test the by-pass functioning (reading the T° on the synoptic).
When BYpass is opened, Tean = Tsan,
When bypass is closed, Tean =/= Tsan if Tean =/= Teav
