Measurement address
Setting of the digital input address for air flow measurement.
Measurement extra
Setting of the digital input addresses of the air flow measurements of the extra fans.
Type ProFlow
Setting indicating the type of ventilation. Select from:
•
Standard
: ventilation control for fan and control valve based on RPM feedback.
•
Multi
: can be used if several Reflow controls with feedback are used. The fan voltage
will be increased to increase the stability of the fan control.
•
Energy efficient
: ventilation control for fan and control valve based on RPM
feedback. Fan voltage will be lowered further and the control valve opened wider
than with
Standard
setting.
•
Natural
: ventilation control for fan and control valve based on RPM feedback
whereby the fan can be switched off if there is enough natural draught (thermal).
Modulating
Setting indicating the required modulation type (
NONE
/
OPTIMAL
/
FIXED TIME
).
Modulating: NONE
Do not use modulating fans.
Modulating: OPTIMAL
Modulate under %
Setting of the ventilation percentage, below which the control computer will apply
modulating control to the linearly controlled part.
Optimal ON-time
Setting of the ON time the control computer tries to achieve (this
ON time
is minimum 10
seconds).
Maximum cycle time
Setting of the maximum duration of a cycle (
ON
plus
OFF
period).
Calculated cycle time
Readout of the actual cycle time
Calc. ON / OFF time
Readout of the actual
ON/OFF time
.
Modulating: FIXED TIME
Modulate under %
Setting of the ventilation percentage, below which the control computer will apply
modulating control to the linearly controlled part.
Setting of the ventilation percentage, below which the control computer will apply
modulating control to the linearly controlled part.
This applies to fans that cannot be controlled below this percentage. Linearly controllable
fans usually have a minimum ventilation level. The control computer cannot ensure
reliable fan control below this level. Modulating control can be used below this level.
Cycle time
Setting of the duration of a cycle (
ON
plus
OFF
period).
Calculated ON/OFF-time
Readout of the actual
ON/OFF time
.
