Icon Fan mode
The fan is controlled by a pressure regulation.
The fan is controlled by a volume flow control.
OFF The operating mode "Switched off (OFF)" is set: The fan is
switched off and cannot be switched on by the control.
NOTICE!
Applies only for devices with the function "Heating": The control-
ler has a "Frost protection function", i.e., if the room temperature
drops to below 4°C, the heating valve is also opened for the air
treatment unit for selected fan mode OFF.
NOTICE!
The manual setting "OFF" for fan off has a higher priority than a
setting for the economy mode of a MATRIX.DI/Clock or
Matrix.LON, e.g. if "OFF"is set at the control panel fan, the unit
switches off and the unit furthermore remains OFF if switched
over via Matrix.DI/Clock or MATRIX.LON in the economy mode.
Use the "Operating mode" icon to display the current setting for operating the con-
trol system by one of three icons.

mode" menu.

mode" menu.

ation).

nal time program control (e.g. MATRIX.OP71) or control contact
with DI input module (MATRIX.DI) is switched off manually. The op-
erating mode setting remains for the time period up to withdrawal of
the "normal operation" entry.
