4.1.4 Mixed control 2
Used for variable speed control on stage 1.
The other fan stages are controlled in series when the 1st stage is at 100%.
The following diagram illustrates this operating mode for a system with 6 control stages.
● Regulation of floors On/Off (AC fans):
- If the fluid temperature> A121 + A106 and when
the temperature continues to rise for> A107
regulation put into operation an additional control
stage.
- If the fluid temperature <A121-A106 and when the
temperature continues to drop for a period <A108
the control, cut a regulation stage
- If the fluid temperature (measured) is between
A121 - A106 and A121 + A106, there is no action
on the stage of AC fans.
