6.4.1.1
Inlets and Chimney Dampers’ Operation
The opening/closing of chimney dampers and air inlets is linked with the activation of
the fan stages. The user sets an inlet and a damper opening associated with each fan
stage. When the start temperature of a fan stage is reached, the inlets and damper
reach the opening associated with that stage.
During the minimum ventilation cycles:
When the fans are off: the inlets/dampers are at the opening defined for stage 0.
When the fans are on: the inlet/damper are at the opening defined for stage 1.
With Variable Outputs:
If variable stages are used, two additional openings must be set: an opening corre-
sponding to the beginning of the variable fan stage and an opening that is reached
when the variable fan stage attains its maximum speed.
