TA5 TA4 TA3
+/- are used to define the following:
+ constant flow (constant flow control switched on)
- constant flow (constant flow control switched off)
For the function
+constant flow (constant flow control ON)
, the system needs to be equipped with the
analogue flow sensors for supply air Fz2 and exhaust air Fz3.
The flow sensors were calibrated by pairs before delivery.
If constant flow control is not desired, the air flow is regulated via PWM control of the ventilation fans.
For
–constant flow (constant flow control OFF)
, no flow sensors for supply air Fz2 and exhaust air Fz3
are needed in the system.
+/- SUP/EXT
for (+) positive fan adjustment (e. g. ebm fans of series campus, thermos , atmos)
for (-) negative fan adjustment (e. g. Papst fans of series multi, climos)
are used to adjust the response of the ventilation fans.
Fan power for each ventilation step is adjusted by means of the buttons TA3 to TA5.
The fan power ratio is adjusted with the coefficient of correction, e.g.
100 : 100 Equal power for supply and extract air
100 : 120 Extract air higher than supply air
100 : 080 Supply air higher than extract air
Use TA2 to change the step width (increments of 1 or 10).
It is not possible to set the fan power for supply and extract air to values higher than 100, because the fan
cannot yield more than 100% and the control would no longer work properly. For a correction value > 100,
it may be required to lower the “max” ventilation step until the values for both fans are
≤
100.
The "min” ventilation step may not fall below 030.
While the entries are made for min, normal, max values, the ventilations fans run at the currently adjusted
speed so that it is possible to calibrate the system.
Calibration is done at “normal" ventilation.
