9. DAMPER SECTION
The function of dampers is to control air supply to ducts, to close unit when the system is off, to prevent cold air to get in to the premises.
Damper can be controlled manually with handle or automatically with actuator.
Damper actuator control types: open / close or modulating (0-10V).
Open / close actuator:
Figure 9.1 – damper actuator wiring diagram:
(1) – open-close with spring back actuator control; (2) – open-close actuator control; (3) – 3-point actuator control;
Modulating (0-10V) actuator:
Figure 9.2 – Modulating actuator (0-10V) wiring diagram:
Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from
rotating.
Manual operation is possible with the pushbutton (the gear is disengaged for as long as the
button is pressed or remains locked).
Adjustable angle of rotation with mechanical end stops.
The actuator is overload-proof, requires no limit switches and automatically stops when the
end stop is reached.
The actuator rotation direction can be changed.

Safety notes:
Assembly must be carried out by trained personnel. Any legal regulations or regulations
issued by authorities must be observed during assembly.
