Siemens Building Technologies Division launches a new generation of its proven line of RAA and RAB room thermostats. The products are of modern, ergonomic design and ensure a high level of energy efficiency thanks to improved switching accuracy.

Room thermostats of the RAA line have an on/off switch and a large, ergonomic setting knob for adjusting the desired room temperature. The room thermostats of the RAB line, which have been developed for use with 2-pipe fan coil units, feature an operating mode selector and a manual switch for controlling a 3-speed fan – in addition to the setting knob.

The products are suited for all types of standard applications in the heating and cooling field and are used in connection with thermal and zone valves plus fans.

The larger temperature setting knob of the new generation affords more accurate operation, resulting in better switching accuracy and thus in higher levels of energy efficiency of heating or cooling plants.

What's more, the new products are accommodated in more compact housings. Thanks to their optimized design, the room thermostats require less space in the room and are less noticeable.

Owing to their rugged construction, the new room thermostats are suited not only for residential and non-residential buildings, but also for use in light industrial buildings.

The room thermostats of the RAA and RAB lines are part of Siemens' Environmental Portfolio. In fiscal 2010, revenue from the Portfolio totaled about €28 billion, making Siemens the world's largest supplier of ecofriendly technologies.

In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by 270 million tons, an amount equal to the total annual CO2 emissions of the megacities Hong Kong, London, New York, Tokyo, Delhi, and Singapore.​
