Programming Inlet Openings
Once the calibration is completed, you must assign an inlet position to each
ventilation stage of the environment controller. This position can either be
specified as a moving time of the actuator or as a percentage of the total run
time, depending on the chosen option (see OPENING DISPLAY chapter).
BEFORE PROGRAMMING INLET OPENINGS
•
Install a static pressure measuring device or determine in advance
the position required at each reference point by calculating, ac-
cording to the fan airflow, the opening that will maintain the de-
sired air speed at the inlet.
•
Enter the total opening time of the inlet of each TC5-ITA unit.
PROGRAMMING INLET OPENINGS:
•
Select "PROGRAMMING" using the function selection buttons (note
that this menu is not available during the calibration) The opening
time or the inlet position (in %) associated with step 0 is displayed.
Moving times are displayed as follows:
- A negative time value signals a closing time;
- A positive time value signals an opening time;
- The word "Off" means that the inlet completely closes once
the temperature controller reaches the selected step.
•
Use the adjustment buttons to specify the opening time or the inlet
position (%) associated with step 0 (if required).
•
Press the right-arrow key to select the next step.
•
Use the adjustment buttons to specify the opening time that needs
to be added to the previous opening, or to specify the inlet opening
(in %) associated with the selected step.
•
Proceed in similar fashion for all steps.
