Room actuator

The room actuator is used to control electrical loads of three different building systems that are typically used in a residential, office or hotel room:The first four relay outputs of the room actuator can be set in the ETS software configuration either to blinds operation or alternatively to switching operation; mixed operation of these two modes of operation is also possible on the device. In blinds operation the relay contacts of the room actuator can be used to control electrically driven blinds, shutters, awnings, venting louvers or similar curtains for 230 V AC mains voltage. Alternatively, the actuator can switch electrical loads such as lighting systems in switching operation. The relay contacts are bistable, which means that the last switching state set remains unchanged even in the event of a mains voltage failure.

Furthermore, the room actuator has two additional electronic switching outputs, which allow si-lent control of electrothermal valve drives for heating or cooling systems. Up to 4 electrothermal valve drives can be connected to each of these electronic outputs, which are protected against overload and short-circuit.

By combining the functions of the room actuator´s outputs, in many cases it is possible to plan and execute electrical installations on a room-specific basis.

The functionalities that can be preset with the ETS independently for each output channel in blinds operation include, for instance, separately parameterizable travelling times, enlarged feedback functions, assignment to up to 5 different safety functions, an extensive sun protection function, and incorporation into scenes or forced-position applications. Centralized control of all blind outputs is also possible.

In switching operation the functionalities for each output include, for example, extensive time functions, logic operations, scenes, disabling functions or alternatively forced positions, expan-ded feedback telegrams, cyclical monitoring of the incoming telegrams and an operating hours counter. Here, too central switching of all switching outputs is possible.

Each of the electronic switching outputs has the following scope of functions: conversion of con-stant command value telegrams into a pulse-width modulated output signal (PWM). This provides quasi-constant activation of the the connected valve drives. Alternatively, conversion of switching command values. Status messaging for valve position and cyclical monitoring of the command value telegrams. Emergency operation in the event of bus voltage failure or bus and mains voltage return and forced position via bus telegram in summer and winter mode. Alarm message in case of short-circuit or overload of the switching output and anti-sticking protection for the valves. Valve drives that are closed or open when deenergized can be connected.

What is more, the room actuator monitors the mains voltage and makes it possible to transmit an alarm message to the bus in the event of a fault. The status messages "all valves closed" and "largest command value" can be transmitted to the bus in common for the two electronic switching outputs for further processing or displaying the information on other bus devices.

The controls (4 pushbuttons) on the front panel of the device permit switching the relays and also the electronic switching outputs on and off by hand even without bus voltage or in a non-programmed state. This feature permits fast checking of connected loads for proper functioning.

ETS3.0d is recommended for configuration and commissioning of the device. The advantages with regard to downloading (shorter loading times) and parameter programming are available only if this new ETS patch version or later versions are used. For ETS2 and older versions of ETS3, a separate product database is available.

The room actuator has its own mains voltage connection that is independent of the connected drives or loads. For activation of the outputs the 230 V mains voltage must always be switched on. The device electronics (BCU with application program) are supplied with power from the bus or from the mains. The device is designed for being mounted on DIN rails in closed compact boxes or in power distributions in fixed installations in dry rooms.
