41. GeneralThe ASH 2200US radio climate sensors make itpossible to determine values for temperature andhumidity at the location of the sensor and to transmitthe data by radio to a reception station suitable for thispurpose, for example to the ELV BA 1010US. Thesensors can be flexibly mounted at different locations:outdoors, in the green house, in the cellar, garage,storage room and many other places. Thispermits you to install a complete monitoring systemconsisting of diverse locations.Functional features:ASH 2200US- Freely addressable, battery operated, radio universaltemperature and humidity sensor for the temperaturerange -30.0 ˚C to +70 ˚C and the humidity range 5 %to 95 % relative humidity.Please read these instructions fully and thoroughlybefore initial commissioning; they contain informa-tion for the correct use of this device.Intended useThe external sensing device ASH 2200US can be usedoutdoors in a temperature range of -30 ˚C to +70 ˚C anda maximum humidity of 95 %. Please observe theinstructions regarding the choice of installation location.The manufacturer does not accept any liability for theconsequences of improper use; all rights under thewarranty will be forfeited.
52. Safety and maintenance information- The device has no user-serviceable parts.- Avoid extreme moisture (e.g. it should not be directlysplashed with or immersed in water), direct sunlight,and extremely dusty environments.- Clean the display device and the external sensorusing a dry linen cloth, which may be slightlydampened to remove obstinate soiling. Do not usesolvents for cleaning- The device should be kept out of reach of children. Itis not a toy!
63. Commissioning3.1. Inserting the batteriesRemove the protective cap on the external sensor andopen the battery compartment as shown in the picturebelow.Insert two 1.5 V Mignon batteries (LR 6 / Mignon /AA alkaline) into the battery compartment, ensuring thatthe polarity iscorrect (see illustration), and then close the batterycompartment.Place the protective cap back on to the stop.CAUTION! Observe regulations for the disposal of12batteries!Used batteries and rechargeable accumulatorsmust not be thrown away with householdrubbish!Please take exhausted batteries and recharge-ables to your local dealer or to a collection pointfor hazardous waste or batteries.
73.2. Sensor addressingEach sensor in the weather monitoring system isassigned an address which enables the receiver tointegrate the sensor trouble-free into the system.The factory setting for each sensor is address 1. Eightaddresses are available (1 to 8, corresponding to thedisplay).You can carry out addressing yourself using thejumpers on the sensor circuit board.To do that, the protective cap must first be taken off ofthe sensor housing and the batteries removed.You then remove the two screws on the back which areon the left and right of the wall holder, remove the screwabove the battery compartment, and take off the fronthalf of the housing.

8The jumpers can now be placed according to theaddress table.The black areas represent a jumper inserted at one ofthe points (1, 2, 3).3 2 1Adresse876543213.3. Installation and dismounting of the externalsensorThe external sensor can be very easily installed on avertical surface using the supplied mounting base.CAUTION!Choose an installation location that is not exposed todirect precipitation, direct sunlight, or is extremelydusty! Outdoor installation under a roof overhang, forexample, would be a suitable location.
9The mounting base is fastened onto a vertical surfacewith a screw as shown in the following figure. Make surethat the notch in the housing points up as in the drawing.Notch points upwardScrew holeNow the external sensor can be inserted vertically to thestop in the mounting base.If the external sensor needs to be dismounted (e.g. tochange batteries), it is pulled out to the front.
104. Range and reception interferenceThe free field range (i.e. the range of the line of sightcontact between the transmitter and the receiver) is100 m under optimum conditions. Walls and evenreinforced concrete can be penetrated, which does,however, reduce the range.In the event of interference, turn the display unitslightly until it is again receiving data from therequired sensor.A reduced range can have the following causes:●High frequency interference of all kinds●Buildings of all types or vegetation●The distance of the transmitter or receiver fromconductive surfaces or objects (even to the humanbody or the ground) has an effect on the radiationcharacteristics and therefore the range.●Wide band interference in built up areas can reachlevels that reduce the signal-noise ratio throughoutthe frequency band which reduces the range.●Devices working on adjacent frequencies can alsoaffect the receiver.●Badly shielded PCs can radiate into the receiver andreduce the range.
115. Changing the batteriesThe batteries in the sensors have a life of up to threeyears (alkaline batteries). They must be changed whenthe respective sensor does not appear in the displayunit and there is no general and long lasting interfer-ence of the radio path, which can usually be recognizedwhen there is no data transmission from other, neigh-bouring sensors either (see Section 4 “Range and re-ception interference”).Batteries are changed as described in Section 3.1.Following a battery change, the sensor is ready foroperation again after a test run in test mode (see“Technical data”).6.

127. FCC Information FCC ID: RNT-ASH2200USChanges or modifications not expressly approved in writing byELV Electronics Limited may void the user’s authority to operatethe equipment.NOTE: This equipment has been tested and found to comply withthe limits for a Class B digital device, pursuant to Part 15 of theFCC Rules. These limits are designed to provide reasonableprotection against harmful interference in a residential installation.This equipment generates, uses and can radiate radio frequencyenergy and, if not installed and used in accordance with theinstructions, may cause harmful interference to radiocommunications. However, there is no guarantee that interferencewill not occur in a particular installation. If this equipment doescause harmful interference to radio or television reception, whichcan be determined by turning the equipment off and on, the useris encouraged to try to correct the interference by one or more ofthe following measures:- Reorient or relocate the receiving antenna.- Increase the separation between the equipment and receiver.- Connect the equipment into an outlet on a circuit different fromthat to which the receiver is connected.- Consult the dealer or an experienced radio/TV technician forhelp.The internal antenna used for this mobile transmitter mustprovide a separation distance of at least 20 cm from allpersons and must not be co-located or operating inconjunction with any other antenna or transmitter.This device complies with Part 15 of the FCC Rules. Operationis subject to the following two conditions:(1) this device may not cause harmful interference,and(2) this device must accept any interferencereceived, including interference that may causeundesired operation.
