The "Fan" submenu is for setting the parameters for the continuously variable
speed regulation of supply-air and extract-air motors. It appears when using the
control panel with central or low-profile unit control MATRIX 4700 in connection
with frequency converters.
The individual parameters are specified by selecting the following submenus:
– Control mode
– Factor or speed offset
– Maximum volume flow
Whether the submenu "Factor" or "Speed offset" is shown or not is determined
dynamically by the selected "Control mode" (see Fans Ü Control mode on
Page 71).
Fans ➜ Control mode
In the "Type of the control" submenu you must select how the speed setpoint
value for the supply-air and/or extract-air fan should be set.
The following table demonstrates different combination options for supply-air and
extract-air fans. If the setting "Offset" or "Factor" for a fan is selected, the associ-
ated submenu appears (see fans Ü factor on Page 73 or fans Ü fan speed offset
onPage 73).
