[. . . ] switching a light ON and then OFF. unit fan mode room temperature F Fig. Default Display thermometer symbol 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. The function in effect at any particular moment is indicated by the presence in the LCD of the function indication bar (see Fig. [. . . ] 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 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 (" "), meaning that the user wishes to 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 (" "), meaning that the user wishes to override 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 (" "), meaning that the user wishes to override 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. 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). 3 EN1B-0398GE51 R1207A T7270B2009 WALL MODULE NOTE: This design solution was chosen to avoid confusion stemming from the fact that the T7270B2009 is not capable of receiving (and therefore displaying) information from the W7070A2000 about the actual occupancy state currently in effect. Cycling with the UP button results in the following sequence of displays: "crescent moon", then nothing, then "half-sun", then "full sun". NOTE: The OCCUPANCY function can be disabled (see section "PA: Disable/Enable OCCUPANCY Function" on page 6). When cycling with the "F" button, this function and the corresponding display in the LCD sequence will then be unavailable to the user. Default Function The LIGHT function is the default function. After the LCD test is then automatically performed, the name of the current software version in the T7270B2009 (e. g. "1. 03") 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 transmitted. Default Display and Default Function If there is no user action for more than 4 sec, the T7270B2009 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. EN1B-0389GE51 R1207A 4 T7270B2009 WALL MODULE CONFIGURATION MODE By configuring the T7270B2009, 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. 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 T7270B2009 is now ready for configuration. Then press the "F" button again and, while still pressing it, rotate the setpoint wheel to the desired parameter (e. g. RESULT: The LCD cycles through the various different parameters (P1 through PB) together with their current configurations. Release the "F" button and rotate the setpoint wheel to select the parameter value (e. g. [. . . ] Remove any discharged batteries, if necessary. 2. NOTE: Batteries should not be disposed of in the household garbage. You may be required by local law to dispose of discharged batteries in a certain manner. Insert the supplied (or replacement) batteries into the battery compartment. Low Batteries If the batteries are nearing the end of their useful life, the word "BATT" will appear in the LCD. This means that the batteries must be replaced (see section "Inserting Batteries" above). 7 EN1B-0398GE51 R1207A T7270B2009 WIRELESS WALL MODULE DIMENSIONS 86 100 68 97 99 85 F 104 2 Honeywell 30 Fig. [. . . ]
