Mounting and installation notesThe QAW810 should be mounted in a location where the air temperature can be acquiredas accurately as possible without getting adversely affected by direct solar radiationor other heating or cooling sources..• Mounting height is about 1.5 m above the floor.• The unit can be fitted to a recessed conduit box.• The specified ambient conditions must be observed.• Only authorized staff may remove the QAW810 unit from its base.• Do not mount in recesses, shelves, or behind curtains or doors.• Refer to the Mounting Instructions included in the packaging box.When mounting the unit, fit the base first and then make the electrical connections. Toavoid damage during construction work, install the QAW810 only when all constructionwork is completed. The QAW810 must be mounted on a flat surface and in compliancewith local regulations.Local regulations for installation must be observedSTOP Note!The room unit is not protected against connection to AC 230 V!Commissioning notesResponse on startupSensor calibrationCommissioningWhen powering up, the QAW810 will display all LCD symbols for approximately 2 seconds.The LCD will then revert to normal display. There will be a delay before operationcommences due to polling of all values.Generally, there is no need to calibrate the sensor. However, the room temperaturedisplayed can be calibrated if there is a deviation from the actual temperature measuredby a certified thermometer.The calibration function can be accessed by pressing the and buttons simultaneouslyfor 2 seconds. The displayed value can then be readjusted, using the same buttons,in 0.5 K increments. The readjustment range is ±2 K.Initial installation-specific application setup is made by the setting of DIP switch positionson the RRV817 controller. DIP switches are located at the top of the RRV817controller’s PCB.The QAW810 features DIP switches for zone addressing. In addition to the QAX810master zone, using the QAW810, up to 6 further zones can be connected to theRRV817 controller. The QAX810 master room unit is always zone 1 (automatic - noaddress setting necessary).Siemens Zone Room Unit QAW810 AP1N2724enBuilding Technologies 28.08.20073/6
