•
the "AUTO" symbol, meaning that the user does not wish
to override the fan setting automatically established by the
controller, or
•
the "MANU" symbol, meaning that the user wishes to
override the fan setting automatically established by the
controller, together with the numeral "0", "1", "2", or "3"
(representing the fanspeeds).
Cycling with the UP button results in the following sequence
of displays: "AUTO", then "MANU 0", then "MANU 1", then
"MANU 2", then "MANU 3". Cycling with the DOWN button
reverses the sequence.
After the selection has been completed, the "AUTO" / "MANU"
symbol will become part of the default display.
NOTE: The FAN function can be configured so as to be
disabled whenever the user has manually forced the
controller into the "unoccupied" state and parameter
P8 (see page 6) has been set to 3 or 4. When
cycling with the "F" button, the FAN function and the
corresponding display in the LCD sequence will then
be unavailable to the user. If the FAN function is not
available, check parameter P8 to see if it has been
disabled and/or change the occupancy state.
NOTE: The FAN function can be configured for "no fan",
"ON/OFF fan", "2-speed fan" or "3-speed fan" via
parameter P3 (see section "P3: Fan" on page 6). If
the fan does not work as expected, check the
settings of parameter P3.
Default Display and Default Function
If there is no user action for more than 4 sec, the wall module
will automatically revert to the default display and the default
function.
Default Display
In the default display (see for example Fig. 2), the current
room temperature (in °C or °F, as desired) with a resolution of
one-tenth of a degree is shown in the LCD. Further, the
temperature symbol – a stylized thermometer (" ") – is also
shown.
Default Function
The LIGHT function is the default function. Thus, the user can
adjust the setting (i.e. dim, brighten, or turn a light group
ON/OFF) simply by using the UP and DOWN buttons, and
without having to cycle through the other function symbols.
Power-Up / Teach Commands
After power-up, an LCD test will be carried out (i.e. all LCD
segments will be activated for approx. 1 sec).

After that, two teach commands will be triggered. Please
refer to W7070A Receiver – System Engineering (Product
Literature No.: EN0B-0286GE51) on how to perform a teach-
in. A special LCD sequence "t 1", then "t 2" will be shown
while the given teach command is being sent.
Checking the Software Version and Sending
Teach Commands
To check the version of the software currently loaded in the
wall module, the user must press the "F" button and the
DOWN button simultaneously for approx. 5 sec.
After the LCD test, the name of the current software version
in the wall module (e.g. "1.01") will appear in the LCD and a
special LCD sequence "t 1", then "t 2" will be shown while the
given teach command is being sent.
CONFIGURATION MODE
By configuring the wall module, the user can alter its functions
/ displays to better reflect the actual operating environment
(e.g. the presence of a fan, the number of speed levels it has,
the number of light groups, etc.) in which it is used. To
configure the wall module, proceed as follows:
1.
Press the "F" button and, while still pressing it, press the
UP button (for at least 5 sec).
RESULT: "P-:--" appears in the LCD, indicating that the
wall module is now ready for configuration.
2.
Release both buttons. Then press the "F" button again
and, while still pressing it, rotate
desired parameter (e.g. PA).
RESULT: The LCD cycles through the various different
parameters (P1 through PB) together with their current
configurations.
3. Release the "F" button and rotate the setpoint wheel to
select the parameter value (e.g. "1" or "2").
4. Confirm your selection by pressing the UP button
5. You may now continue configuring – or leave the con-
figuration mode and permanently store your configurations
by pressing the DOWN button.
Configuration Parameters
P1: Temperature Unit
With this parameter, the user can configure the unit (°C or °F)
in which the room temperature and (relative) temperature
setpoint offset are displayed:
•
P1:1 → Temperatures are displayed in °F.
