Figure 14. Static Pressure Screen
If you have elected not to use the optional static pressure control
device, when you press this button it will advise you that static
pressure is not in use.
1. Current Static Pressure - This tells you the current static pressure. This is not
an editable field.
2. High Pressure Limits -
Power Mode - the control will open the air inlets if the static pressure increases
above this value while in power mode.
Tunnel Mode - the control will open the tunnel curtain if the static pressure
increases above this value while in tunnel mode.
3. Low Pressure Limits -
Power Mode - the control will close the air inlets if the static pressure decreases
below this value while in power mode.
Tunnel Mode - the control will close the tunnel curtain if the static pressure
decreases below this value while in tunnel mode.
In all cases, the control opens or closes the air inlets or tunnel
curtains until the static pressure is corrected back into the
acceptable static pressure range.
4. Wind Delay - this is the amount of time in seconds that the static pressure needs
to be outside of the defined limits before the control reacts by opening or closing
inlets. This delay does not occur if a fan or fans have just turned on or off. In fact,
if a fan or fans turn on after no fans have been running, (minimum ventilation
timer situation) the air inlets will open first.
Inlet anticipation - the control opens the air inlets before it turns on
the fan(s) when conditions first call for a fan(s) to run. This feature
results in more stable static pressure.
