Operating the outputs
In the manual control mode, the outputs can be
operated directly. Depending on programming, the
operation of switching one output may also affect
other outputs.
The device must in the permanent or temporary
manual control mode.
- Press the
key repeatedly until the desired
output
is
selected.
The LED of the selected output A1...A8 is flashing.
The ON /3 and the OFF / 4 LEDs indicate the
status.
- Output operation with the ON /3 or the OFF / 4
key.
• Heating/cooling outputs : opening or closing
the valve.
• Fan outputs : selecting the fan stage.
• Switching outputs : switching on or off.
The selected output switches on or off.
The ON /3 and the OFF / 4 LEDs indicate the
status.
H
• Depending on programming and selected
output, several outputs are switched at the
same time.
• Heating and cooling of a fan coil output are
never activated at the same time.
• When the heating or the cooling output is
active, at least the first fan stage is active as
well.
• Temporary manual control: after all outputs
have been selected one after another, the
device quits the manual control mode with
the next brief press.
Switching off all outputs
The device must in the permanent manual control
mode.
- Press the ALL OFF key.
All outputs are switched off.
Disabling individual outputs
The device must in the permanent manual control
mode.
- Press the
key repeatedly until the desired
output
is
selected.
The LED of the selected output A1...A8 flashes.
- Press the keys ON /3 and OFF / 4 simultane-
ously for at least 5 s.
The selected output is disabled.

Outputs that are not used for fan stage control
can be used for simple switching. Assignment
of output terminals see project design data.
1- Connect the bus line to the bus terminal 4.
2- Connect the mains supply 5.
3- Connect the fan coil units to the actuator outputs
as provided for in the project design.
