Dampers; Damper Modulating Regulation; Control In Fixed Opening - Evco c-pro 3 micro AHU Applications Manual

EVCO S.p.A.

5.16 Dampers

The program provides the management of a motorized shutter for the intake of outdoor air to support the room
temperature control. The type of management is determined by parameter PG07, in the configuration menu.
PG07=0: Disabled
-
PG07=1: Enabled in modulating control
-
PG07=2: Enabled in fixed opening
-
Damper can be command by 2 DO of opening and closing, or by an AO (parameter PS04)
Note: on the configuration PG00=5 and PG00=6 is not possible to connect the dampers on the analogue outputs. For
the other configurations, can be connected on any of the available analogue outputs.
5.16.1

Damper modulating regulation

In modulating control, the shutter can be utilized for:
Free-Cooling / Free-Heating in temperature (parameter PS01=1)
-
Air quality control (parameter PS 02=1)
-
The control also provides a position of minimal opening of the shutter to guarantee the minimal quantity of projected
renewed air (parameter PS05) and the corresponding maximum position of the opening (parameter PS06).
5.16.2

Control in fixed opening

In this mode the outdoor air dampers always assumes the same value of opening as decided by parameter PS10. In
this control the range of values of opening is from 0% to 100%, there is no minimum value for the opening.
to utilize this control it is necessary to set PG07=2.
Note: with this modality the free-cooling, free-heating and the air quality control cannot be utilized.
