ThemostimportantruleforlocatingtheOutdoorTemperatureSensoristhatitshouldhavethesametemperature,wind,and
solarconditionsastheoccupiedrooms.Inmostcases,theOutdoorTemperatureSensoristobemountedonthecoldestside
of the building (N–NW side) so as not to be affected by direct sunshine. This is to ensure that it will be warm enough in each
room of the house. Only when the windows of all the rooms to be regulated face in the same direction can the sensor element
be mounted onto the outside of this same wall. This can also be the south side of the house. The Outdoor Temperature
Sensor’s protective housing prevents the sun’s rays from affecting the sensor. If the sensor has been mounted on the south
sideofahousewithlargewindowsfacinginthisdirection,itisrecommendedthatyouremovethesunguard.Donotmount
theOutdoorTemperatureSensorinaprotectedarea,suchasawallnicheorunderthebalcony.Itshouldbeputonanopen
façade so that it can detect all weather conditions. Avoid mounting the sensor above doors and windows since warm air
movementsmayotherwiseinuencethemeasurementresults.TheTemperatureSensorshouldbemountedabout2/3the
wayupthewallonbuildingsofnotmorethan3stories;ontallerbuildings,betweenthesecondandthirdstories.
