Programmable thermostats for energy savings and comfort
Room thermostats from Siemens are easy to install and to use. Siemens’ patented control technology ensures constant room temperatures. A comfortable room environment means having the right temperature at the right time. This is why the room thermostats feature settable time programs. They enable users to heat or cool rooms only when needed, which is both costand energy-efficient. Also, the time programs offer a choice of settings. If a room is used differently every day, the heating and cooling phases can be set individually for each weekday. If room usage is always the same, the weekday/weekend program is the perfect choice. With room thermostats from Siemens, you can cover a wide variety of applications:

  • Fan coils
  • Heat pumps
  • VAV
  • Domestic hot water
  • Floor heating
  • Radiators
  • Electric heating
  • Ventilation systems for heating/cooling
  • Chilled ceilings


Temperature sensors
Symaro offers temperature sensors with all important active and passive output signals. The active sensors can be quickly adapted to the situation at hand using a number of different, easily adjustable measurement ranges.

Humidity sensors
When it comes to energy-optimized control concepts, Symaro humidity sensors guarantee fault-free operation for years, even in critical applications. Thanks to the capacitive measurement element, they feature excellent long-term stability with high accuracy, freedom from maintenance and high precision.

Air quality sensors
The air quality sensors cover all requirements and are suitable for every type of building. The high-precision multisensors (CO/VOC), CO₂/T and CO₂/ T/r.h.) are available for room and duct applications, and also with an attractive display.

Pressure sensors
Symaro covers the entire range of requirements for pressure measurement. It comprises sensors for measuring very low to high pressures in all kinds of different media such as liquids, gases, water, refrigerants and air.
