N9ZTTX201MRF WIRELESS TRANSMITTER / LONG RANGE THERMO SENSOR

Thermo sensor Model: TTX201 Instruction Manual Congratulations on your purchasing of our new outdoor thermo senor which can cover up to 50m range in an open area. This sensor is designed for everyday use for the home or office and used to monitor the temperature change of outdoor sites. Description of buttons The remote sensor has 2 function buttons inside the battery compartment 1. [CH] button After the battery installation, the LED blinks slowly every 1.5 seconds and channel number shows ‘1’ to indicate it is now under channel setting mode and is set to channel 1 by default. If the user presses no key within ten seconds, the unit will auto-exit the channel setting. If the user press [CH] button once during the channel setting, the channel number is changed to ‘2’ to indicate the unit is set to channel 2. If the user press [CH] button again, the channel number will be advanced to channel ‘3’ and so on. The maximum channel number is ‘5’ and the unit will be scrolled back to channel ‘1’ at the 5 th press of the [CH] button. 2. [ RESET ] Button Press to hardware reset the unit to factory setting LED indicator Setting procedure to link up with a receiving unit This device is designed for easy set up with no wire installation. The following steps are required to be done in proper sequence to link up with a receiving unit. Please insert batteries for the receiving unit before doing so for the remote unit. 1. Lift off the bracket stand of the RF remote sensor, use a small screw driver to remove the battery cover screws. 2. Insert 2 pieces AAA size batteries according to polarity marking on the battery compartment. 3. The LED blinks slowly to indicate it is under the channel setting mode and the user can set it to other channel by press [CH] key. 4. The temperature of the sensor will appear on the selected channel of the receiving unit if it is linked up with the receiving unit successfully. 5. Screw the battery cover back to the Rf remote sensor. Follow the same procedure (1 to 5) to register other remote sensors. Note: For the user purchasing more than one remote sensor, he must set the sensors to different channel in the start up to avoid conflicts. Precautions a. Do not clean the unit with abrasive or corrosive compound. It may scratch the plastic parts and corrode the electronic circuits. b. Do not subject the unit to excessive force shock, dust, temperature or humidity, which may result in malfunctioning, shorter electronic life span, damaged battery and distorted parts. c. Do not tamper with these units’ internal components. Doing so will invalidate the warranty on the unit and may cause unnecessary damage battery and distorted parts. d. Do not subject the unit to excessive exposure to direct sunlight. The remote sensor is splash proof. Never immerse it in water or expose to heavy rain. e. Always read the users manual thoroughly before operating the unit. Specification Displayed temperature range : -50.0°C to +70.0°C (-58.0°F to +158.0°F) Proposed operating range : -20.0°C to +60.0°C (-4.0°F to +140.0°F) Temperature resolution : 0.1°C (0.2°F) RF transmission frequency : 433MHz RF transmission range : Maximum 75 meters in open area Batteries : Use 2 pieces UM-4 AAA size 1.5V alkaline battery Caution This device could be sensitive to electrostatic discharge, If electrostatic discharge or malfunctioning occurs please reset this unit. 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. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the 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 from that to which the receiver is connected. --Consult the dealer or an experienced radio/TV technician for help.
