T7270B1009 WIRELESS WALL MODULE
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 wall module 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 wall module (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 tem-
perature 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 wall module 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 5). 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 5.
Controlling a Single Light Group (P6:1)
If the wall module has been configured to control only a single
group of lights (see section "P6: Light Groups" on page 6), 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 sub-
sequently 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 wall module has
been configured to control two light groups (see section "P6:
Light Groups" on page 6). 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 sent only after
the UP button is finally released. Thus, only one light
group can be turned ON/OFF at a time.
