Operating Instructions
Roller shutter timer
Timer U26
The timer U26 is an electronic roller shutter timer for operating a 230 V tubular
drive. If more than one drive is controlled using the U26, the drives must be de-
coupled by relay controls. There is no need for decoupling in the case of drives
with electronic limit switching.
The U26 timer can easily be extended to form a convenient sun protection con-
trol unit, providing additional light-dependent control for the roller shutter, using
the LS26 light sensor, which anyone can attach without difficulty. You can obtain
the LS26 light sensor, as well as other control elements, from your roller shutter
dealer.
Caution
• Please keep the instruction manual safe!
• Risk of injury due to electric shock.
• Connections to the 230 V mains must always be performed by a spe-
cialist.
• Disconnect the connecting cable from the power prior to installation.
• Always comply with regulations of local energy supply companies as
well as VDE 100 provisions for wet and damp rooms during installa-
tion.
• Only use in dry rooms.
• Only use unmodified original parts from the control unit manufac-
turer.
• Keep people out of the system’s range of travel.
• Keep children away from control units.
• Observe all pertinent country-specific regulations.
• If the system is controlled by one or several appliances, the system’s
range of travel must always be visible during operation.
• When connecting the control cables (protected extra-low voltages),
only use cables with sufficient electrical strength.
• Device contains small parts that can be swallowed.
The U26 is designed for fitting in a flush-mounted switch box or a surface-
mounted housing. Install as follows:
• Remove the front plate by pulling it off.
• Pull the connecting terminal off from the rear of the timer (plug-in terminal),
and make the electrical connections according to the connecting diagram
(Fig. 1). Avoid unnecessarily long connecting wires.
• Push the connecting terminal on.
• Fasten the timer by inserting the two screws supplied in the holes of the
flush-mounted box (Fig. 2).
• Then switch on the power supply. Please note that the first time the unit is
operated, there may be a delay in switching on the timer, as the timer must
first must initialise itself. The number
(Fig. 3) will appear flashing on the
display within 10 seconds.
If, after a power failure (5 hours), or at the time of initial installation, nothing ap-
pears on the display within 10 seconds, press the "Reset" button illustrated on
Fig. 2.
now appears flashing on the display.
• Now check the direction in which the drive is operating using the UP (
)
and DOWN (
) buttons. If the roller shutter moves in the opposite direction
to the button you have pressed, turn off the power to the system and swap
the connecting wires for the UP and DOWN commands at the connecting
terminal.
• After you have made the settings for the time, the switching times and the
sunlight-twilight parameter (the sunlight-twilight parameter can only be ad-
justed when the sensor is connected), fit the front plate.
