Control Settings
The ECON CONFIG menu includes the following control
parameters:-
1. MANUAL / AUTO -- Allows the control output to be set
to Auto or Manual control, manual control is shown
as 0-100% and can be adjusted using the + / - buttons.
In Auto control the output will automatically adjust to
maintain the velocity set point.
2. HIGH SET POINT -- This is used to enter the required face
velocity set point for standard VAV control or the High
set point for dual set point occupancy control.
3. LOW SET POINT -- This is used to enter the required
reduced face velocity set point for dual set point
occupancy control.
4. DAMPER / INVERTER -- This is used to set the output
to 0-10v (direct - for damper) or 10 to 0v (reverse - for
Inverter)
5. MIN OUTPUT -- This is used to set the MIN output
volume when pushbutton III is set to Min/Run/Max
operation.
6. MAX OUTPUT -- This is used to set the MAX output
volume when pushbutton III is set to Min/Run/Max
operation.
7. LOW LIMIT -- This is used to set the fume cupboard
minimum volume when the sash is closed (limits the
damper closed position).
8. HIGH LIMIT -- This is used to set the fume cupboard
maximum volume (limits how far the damper opens).
9. OUTPUT RANGE -- This is used to set the output range to
0-10v (Inverter) or 2-10v (actuator).
10. PROP BAND -- This is the main control parameter
for the VAV control output. If the value is too low the
damper will be unstable and hunt, if the value is too low
the damper will react too slowly. The ideal setting for
this value is to select a value that is as small as possible
but that gives stable control of the damper or Inverter
without ‘hunting’.
11. INTEGRAL TIME -- The Integral Time is the corrective
action of the control output. The PROP BAND control
will result in an offset from the set point, the Integral
will correct the error in small steps over time. The ideal
setting is to select the highest possible value that gives
stable control.
12. INTERAL CUT OFF -- This is a unique parameter that is
used to give a rapid response in control output when
the sash is raised to boost the speed of the output.
The parameter monitors the rate of change of the face
velocity. This parameter should not require changing
from the factory default setting.
13. BOOST DURATION -- The BOOST DURATION is used in
conjunction with a sash position sensor for VAV control.
The controller will drive the output to a pre-determined
position for a brief periof of time before switching back
to face velocity control.
