Fig. 2. Default Display
The function in effect at any particular moment is indicated by
the presence in the LCD of the function indication bar (see
Fig. 2), and a corresponding symbol; e.g. the fan symbol.
OPERATING MODE
Selecting Functions / Adjusting Settings
The user can select the LIGHT, SUNBLINDS, OCCUPANCY,
or FAN functions by pressing the "F" button, whereupon the
current room temperature will disappear from the LCD and be
replaced by the corresponding function symbol. The setting of
the selected function can then be adjusted as desired using
the UP button and the DOWN button.
To adjust a setting, press, as often as necessary (referred to
as "cycling"), the "F" button until the symbol representing the
desired function appears in the LCD. Once selected, this
symbol will be displayed for 4 sec. During this time, the user
can use the UP or DOWN buttons to adjust the setting. If
there is no user action for more than 4 sec, the function
symbol will disappear, and the T7270B2009 will revert to the
default display and the default function.
The SETPOINT OFFSET function is selected and its settings
adjusted using the large setpoint wheel located on the right
side of the T7270B2009 (see section "SETPOINT OFFSET
Function" below).
SETPOINT OFFSET Function
If the SETPOINT OFFSET function is selected (by rotating
the setpoint wheel), the current temperature setpoint offset,
accompanied by the degree symbol and corresponding temperature unit (°C or °F), will appear in the LCD.
NOTE: The SETPOINT OFFSET function can be configured
so as to be disabled whenever the user has used the
OCCUPANCY function to manually force the
controller into the "unoccupied" state and parameter
P8 (see page 6) has been set to 2 or 4. In this case,
the setpoint offset is fixed to 0.0 °.
Adjusting the Setting
The SETPOINT OFFSET function setting can be adjusted by
rotating the setpoint wheel clockwise or counterclockwise,
thus increasing or decreasing (respectively) the setpoint offset
over a range of max. -5...+5 K in steps of 0.5 K.
The setpoint offset range may be adjusted via parameter P4
(see page 6).
NOTE: A snowflake displayed in the lower right corner of the
LCD indicates that the T7270B2009 is transmitting
data. During transmission, the function keys are
disabled; you will thus have to wait approx. 1 sec
between e.g. switching a light ON and then OFF.
LIGHT Function
The LIGHT function is the default function (see section
“Default Function” page 4). The LIGHT function can be
selected by pressing the "F" button until the letters “”LI” are
displayed in the LCD and the function indication bar appears
underneath the light symbol imprinted on the housing.
NOTE: See also section "Default Function" on page 4.
Controlling a Single Light Group (P6:1)
If the T7270B2009 has been configured to control only a
single group of lights (see section "P6: Light Groups" on page
5), the LIGHT function settings are performed as described in
the following sections.
Pressing the UP Button
• Briefly pressing the UP button once turns the light group
ON and causes the word "ON" to appear in the LCD.
• Pressing the UP button for more than 2 sec turns the light
ON and starts dimming the light group. Once 0% is
reached, it starts brightening from 0% to 100%
(100%…0%…100%….). In the LCD, a vertical bar next to
the word "ON" moves continuously from the left to the
right. Releasing the UP button stops the process and
causes the LCD to revert to the default display mode.
Pressing the DOWN Button
• Briefly pressing the DOWN button once turns the light
group OFF and causes the word "OFF" to appear in the
LCD.
• Pressing the DOWN button for more than 2 sec turns the
light OFF and starts brightening the light group. “ON” is
displayed once the brightening starts. Brightening
continues until 100% is reached. Then it starts dimming
from 100% to 0% (0%…100%…0%….). In the LCD, a
vertical bar next to the word "ON" moves continuously
from the right to the left. Releasing the DOWN button
stops the process and causes the LCD to revert to the
default display mode.
NOTE: If, after dimming / brightening the light group, the
user uses the DOWN button to turn it OFF and subsequently back ON, it will be turned back ON at a
brightness level of 100%.
Controlling Two Light Groups (P6:2 and P6:3)
Dimming / brightening is not possible if the T7270B2009 has
been configured to control two light groups (see section "P6:
Light Groups" on page 5). In this case, it is possible only to
turn each group of lights ON or OFF.
The UP and DOWN buttons can be configured by setting
parameter P6 to 2 or 3.

NOTE: The UP and DOWN buttons can also be configured
by setting parameter P6 to 4 or 5 (special custom
models, only).
“UP” = ON and “DOWN” = OFF usage (P6:2)
Pressing the UP Button
Pressing the UP button will turn ON the two light groups as
follows:
• Pressing the UP button once turns ON light group 1, and
the characters "ON 1" appear in the LCD.
• Pressing the UP button twice turns ON light group 2, and
the characters "ON 2" appear in the LCD.
NOTE: The corresponding ON command is transmitted only
after the UP button is finally released. Thus, only one
light group can be turned ON/OFF at a time.
Pressing the DOWN Button
Pressing the DOWN button will turn OFF the two light groups
as follows:
• Pressing the DOWN button once turns OFF light group 1,
and the characters "OFF 1" will appear in the LCD.
• Pressing the DOWN button twice turns OFF light group 2,
and the characters "OFF 2" will appear in the LCD.
NOTE: The corresponding OFF command is transmitted
only after the DOWN button is finally released. Thus,
only one light group can be turned ON/OFF at a
time.
“UP” = Light 1 and “DOWN” = Light 2 usage (P6:3)
Pressing the UP Button for Light Group 1
Pressing the UP button the first time will turn ON light group
1, and the characters “ON 1” will appear in the LCD. Pressing
the UP button again will turn OFF light group 1, and the
characters “OFF 1” will appear in the LCD.
Pressing the DOWN Button for Light Group 2
The DOWN button has the same effect upon light group 2 as
the UP button upon light group 1.
Disabling the Light Function (P6:6)
The LIGHT function can be completely disabled by setting
parameter P6 to 6 (in this case, the SUNBLINDS function
then becomes the default function).
SUNBLINDS Function
The SUNBLINDS function can be selected by pressing the "F"
button until the corresponding function symbol – a stylized
representation of sunblinds (= = = =) – appears in the LCD
and the function indication bar appears underneath the
sunblind symbol imprinted on the housing.
The SUNBLINDS function can be configured via parameter
P5 ("sunblind runtime") as well as by setting parameter P9 to
1 ("no sunblind") or to 2 ("one sunblind").
NOTE: The value of the sunblind runtime must be the same
in the T7270B2009, the W7070A2000, and in the
connected controller (e.g. an XL12).
NOTE: The SUNBLINDS function can also be configured by
setting parameter P9 to 3 or 4 (special custom
models, only) as well as via parameter PB (special
custom models, only).
Refer to section “Configuration Parameters" on page 5 for
details.
Raising/Lowering One Set of Sunblinds (P9:2)
Pressing the UP Button
• Briefly pressing the UP button will completely raise the
sunblinds; in the LCD, the "sunblinds" symbol (= = = =)
moves upwards. Briefly pressing either the UP or the
DOWN button while the sunblinds are rising will stop the
sunblinds, and the LCD will revert to the default display.
• Pressing the UP button for more than 2 sec will raise the
sunblinds only as long as it remains pressed; in the LCD,
the "sunblinds" symbol (= = = =) moves upwards.
Pressing the DOWN Button
• Briefly pressing the DOWN button will completely lower
the sunblinds; in the LCD, the "sunblinds" symbol
(= = = =) moves downwards. Briefly pressing either the UP
or the DOWN button while the sunblinds are descending
will stop the sunblinds, and the LCD will revert to the
default display.
• Pressing the DOWN button for more than 2 sec will lower
the sunblinds only as long as it remains pressed; in the
LCD, the "sunblinds" symbol (= = = =) moves downwards.
When changing directions, the blinds will first stop, tilt, and
then move.
OCCUPANCY Function
If the OCCUPANCY function is selected (by pressing the "F"
button twice), one of the three following function symbols will
appear in the LCD:
• A crescent moon ("
override the occupancy state automatically established by
the controller and manually force it into the "unoccupied"
state, in which it will remain until overruled by a central
control unit or until the user himself changes this by again
invoking the OCCUPANCY function.
• A full sun ("
the occupancy state automatically established by the controller and manually force it into the "occupied" state, in
which it will remain until overruled by a central control unit
or until the user himself changes this by again invoking
the OCCUPANCY function.
• A half-sun ("
the occupancy state automatically established by the controller and manually force it into the "occupied" state for a
limited time (set using the controller's plug-in).
At the same time, the function indication bar will also appear
underneath the printed occupancy symbol. Thereafter, the
T7270B2009 will automatically revert to the default display,
i.e. it will no longer be apparent that the OCCUPANCY function had been invoked.
