Optimum control requires accurate measurements A control operation is only as good as the measuring accuracy of the sensors which detect the control variable (temperature, humidity, pressure, etc.) and transmit it to the controller as an actual value. While this process hasn’t changed, the measuring technology and methods for mounting sensors are more cutting-edge than ever before. Legal regulations increasingly appeal for the economic use of energy. At the same time, the indoor climate must meet stringent requirements. Both requirements can be fully met only if all necessary measured data...

Future-proof building control Everything you need for a good working climate Working concentrated while saving energy – products from Siemens improve the atmosphere in rooms and facilitate more economical operations. The result: perfectly temperature-controlled and air-conditioned rooms with good lighting and reduced energy consumption. Mounting guidelines up to 30 percent energy with individual room control and energy saving functions ■ ■ rotects investments on the basis of reliable products and P the ability to add third-party devices via KNX ■ ■ asy commissioning and adaptation to...

Outdoor temperature sensors Depending on the application, place outdoor temperature sensors as follows: For control The sensors should be mounted on the outer walls with the windows of the main living areas. However, they should not be exposed to morning sunlight. In case of doubt, you can mount these sensors on the north or northwest wall. For optimization not expose to direct sunlight ■ ■ Do not mount on facades with a great deal of ascending heat ■ ■ Do not attach to walls in front of a chimney ■ ■ Do not mount on eaves or a balcony ■ ■ Do not place over windows ■ ■ Do no mount over...

Presence detectors (incl. brightness sensors) Mounting guidelines for presence detectors ■ ■ ake M sure that the workplace is right in the detection zone of the presence detector – without any obstacles such as shelves, plants, glass walls, etc. blocking the detector ■ ■ eep in mind that moving machines, plants and animals in K the detection zone will be interpreted as movement ■ ■ void sources of rapid changes in temperature or light, such A as fans, incandescent or halogen lamps; air flows and light in the detection zone simulate movement ■ ■ ount at least 50 cm away from cables and...

Room sensors for temperature, humidity and air quality To ensure accurate readings, it is a good idea to keep the following in mind during installation: When mounting on massive walls (1) made of steel, concrete, etc., you need to place thermal insulation (2) between the room sensor (3) and the wall. 1 Mounting guidelines for room sensors Clearances between the cable (4) or plastic hose and the installation pipe (5) need to be sealed. Otherwise, inefficient air circulation will occur, causing measuring errors. room sensors in the living area at a height of approx.1.5 meters and a distance...

Outdoor brightness sensors Mounting guidelines for outdoor brightness sensors ■ ■ hen W selecting the mounting site, consider the part of the building (heating zone) for which the outdoor brightness sensor is to detect the incident sunlight; attach the sensor to the wall that contains the windows of the rooms to be affected ■ ■ ount sensors in an accessible location (so they can M be checked) ■ ■ Avoid shade due to trees, neighboring houses, etc. ■ ■ Never paint over sensors ■ ■ Mount the sensor at least 3 m from the ground ■ ■ Mount the sensor at least 0.3 m from the window Mounting...

Wind sensors Mounting guidelines for wind sensors ■ ■ Mount on the facade with the main wind direction a site on the building where the sensor can detect the wind unhindered ■ ■ ount sensors in an accessible location (so they can M be checked) ■ ■ Do not mount under eaves or balconies ■ ■ Do not place in alcoves ■ ■ Consider interference factors such as trees, shrubs and snow ■ ■ Best mounted on a pole ■ ■ Mount the sensor at least 60 cm from interference factors ■ ■ elect S Main wind direction Mounting guidelines Contents Outdoor temperature sensors Motion detectors Presence detectors Bus...
