1. General The ASH 2200US radio climate sensors make it possible to determine values for temperature and humidity at the location of the sensor and to transmit the data by radio to a reception station suitable for this purpose, for example to the ELV BA 1010US. The sensors can be flexibly mounted at different locations: outdoors, in the green house, in the cellar, garage, storage room and many other places. This permits you to install a complete monitoring system consisting of diverse locations.
2. Safety and maintenance information - The device has no user-serviceable parts. - Avoid extreme moisture (e.g. it should not be directly splashed with or immersed in water), direct sunlight, and extremely dusty environments. - Clean the display device and the external sensor using a dry linen cloth, which may be slightly dampened to remove obstinate soiling. Do not use solvents for cleaning - The device should be kept out of reach of children.
3. Commissioning 3.1. Inserting the batteries Remove the protective cap on the external sensor and open the battery compartment as shown in the picture below. 1 2 Insert two 1.5 V Mignon batteries (LR 6 / Mignon / AA alkaline) into the battery compartment, ensuring that the polarity is correct (see illustration), and then close the battery compartment. Place the protective cap back on to the stop.
3.2. Sensor addressing Each sensor in the weather monitoring system is assigned an address which enables the receiver to integrate the sensor trouble-free into the system. The factory setting for each sensor is address 1. Eight addresses are available (1 to 8, corresponding to the display). You can carry out addressing yourself using the jumpers on the sensor circuit board. To do that, the protective cap must first be taken off of the sensor housing and the batteries removed.
The jumpers can now be placed according to the address table. The black areas represent a jumper inserted at one of the points (1, 2, 3). Adresse 321 8 7 6 5 4 3 2 1 3.3. Installation and dismounting of the external sensor The external sensor can be very easily installed on a vertical surface using the supplied mounting base.
The mounting base is fastened onto a vertical surface with a screw as shown in the following figure. Make sure that the notch in the housing points up as in the drawing. Notch points upward Screw hole Now the external sensor can be inserted vertically to the stop in the mounting base. If the external sensor needs to be dismounted (e.g. to change batteries), it is pulled out to the front.
4. Range and reception interference The free field range (i.e. the range of the line of sight contact between the transmitter and the receiver) is 100 m under optimum conditions. Walls and even reinforced concrete can be penetrated, which does, however, reduce the range. In the event of interference, turn the display unit slightly until it is again receiving data from the required sensor.
5. Changing the batteries The batteries in the sensors have a life of up to three years (alkaline batteries). They must be changed when the respective sensor does not appear in the display unit and there is no general and long lasting interference of the radio path, which can usually be recognized when there is no data transmission from other, neighbouring sensors either (see Section 4 “Range and reception interference”). Batteries are changed as described in Section 3.1.
7. FCC Information FCC ID: RNT-ASH2200US Changes or modifications not expressly approved in writing by ELV Electronics Limited may void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
