Explanation of terms/legend
Universal button UT
The switching state of a universal button is not clearly defined after operation. The only thing that occurs is that one contact
switches over from one state to the other. For example, a contact changes from closed state to open state. In the case of a dimmer,
what is meant is the changeover from bright to dark by holding down the button.
Similar terms include single button, changeover switch, toggle, switch back and forth; these terms are used to describe the change-
over from two possible states to the other state. The 4-channel wireless pushbuttons can be assigned with up to 4 universal push-
buttons.
Direction button RT
The mode of functioning of the direction button is the specific switching to a desired switching state. As there are 2 switching states
(ON/OFF or UP/DOWN), two signals are required for direction control and therefore means that button design is highly complex.
Direction buttons are more convenient since switching or dimming is direct. 4-channel wireless pushbuttons can be assigned with
2 direction pushbuttons (double rocker). 1-channel wireless pushbuttons cannot be used for this. It is sufficient to operate the ON
(UP) button to teach in the two direction commands. The opposite command OFF (DOWN) is taught in automatically.
Central commands ZE and ZA
Central control is always used when more than one actuator must be switched to a specific state at the same time. Just as for
the direction button, a separate control signal is required to achieve each switching state. Here are some application examples:
– Central lowering of blinds when the sun shines too hot;
– Central switch-on for panic lighting;
– Central OFF function to save energy when owners leave the house empty;
Central buttons with priority (safety functions) have priority. They are required to control blinds in case of wind, rain or frost, for
example. Activation by local buttons is no longer possible as long as this signal is present.
Scene pushbutton
An existing lighting setting can be saved to a light scene button and recalled exactly at any time later. The switching states (ON/
OFF) or the dimming values are saved in each of the actuators. The lighting setting can be reproduced by simply pressing the
button briefly.
The same applies to sunshading adjustments. Blinds, awnings or venetian blinds can be moved to saved positions. Important:
When a scene is recalled, the previous switching states are not saved. It is therefore not possible to switch a scene on and then
off again later using the same button.
Switch functions
The ON switch function corresponds to the UP switch function (for blind control).
The OFF switch function then corresponds to the DOWN switch function.
ES
Electronic impulse switch
ESV
Electronic impulse switch with off delay
ER
Electronic relay, switching relay
