Page 4: Introduction
Introduction The Sigfox network is used to transmit very short data messages and is optimized for low power consumption. It operates in the unlicensed radio band, which brings cheaper traffic, but also legislative restrictions - messages can not be sent faster than with a 10 minute interval. Ideal applications for transmitters working in the Sigfox network are those where it is sufficient sending measured values with longer intervals (eg 1 h or longer). -
Page 5: Safety Precautions And Prohibited Handling
Safety Precautions and Prohibited Handling Read the following safety precautions carefully before using the appliance, and keep it in mind during use! The device includes a radio transmitter operating in the non-license frequency band with the power specified in the Technical Parameters. This band and performance are used in the countries of the European Union. -
Page 6: Installation
Installation Instalaci Installation, commissioning and maintenance must only be carried out by a qualified person in accordance with applicable regulations and standards. Device Mounting For the optimum operation of the Wx8xx Series, necessary to ensure their Antenna vertical position, usually by screwing them on a wall or other suitable... - Page 7 Optimal positioning of the transmitter in terms of radio range: All materials absorb radio waves if they must pass through them. The most significant in terms of radio wave propagation are metal objects, concrete, reinforced concrete and walls. If you install the device at a greater distance from the base station or in locations where the radio signal difficult to penetrates, observe the following recommendations: ...

Page 8: Switching The Device On
Switching the device on The device is supplied with installed battery, but in off state. The CONFIGURATION button is used to turn on the device: models without waterproof cover (W0841E, W6810, W8810) have CONFIGURTION button accessible via a paper clip through the hole on the top of the device ... - Page 9 If the remote setting in the device is disabled, the bi-directional connection check to the cloud is not performed and the radio connection indicator remains off. Low Battery Symbol – Illuminates if the battery is already weak and flashes when the battery is in critical condition (see the How to replace the battery chapter for details) Information on the display –...

Page 11: Alarm Functions
___________________ Change of device settings by connecting to a PC The transmitter can be set directly from the PC using the SW COMET Vision and Communication Cable SP003 (Optional accessory). Software COMET Vision is downloadable on the web www.cometsystem.com, as well as a manual for its installation and use. - Page 12 after a new alarm is triggered (or an alarm is ended), an extraordinary alarm message is sent within 10 minutes at the latest. Temporary interruption of the current alarm (max. 10 min) is not indicated. See the examples in pics bellow. ...
- Page 13 No even a short-term alarm (i.e. with a duration of 1 to 10 min) will not be lost – the information will be sent no later than 10 min even if the alarm is currently inactive. Device in alarm message sends the maximum value measured during the alarm duration.

Page 14: Manufactured Models
Manufactured models COMET's Wx8xx transmitters differ in the type of measured quantities (temperature, relative humidity, atmospheric pressure, CO concentracion) and the location of the sensors (compact design with internal sensors or external probes on the cable). The enclosure covers electronic circuits, internal sensors, and a one or two batteries. - Page 15 W0841E Four inputs transmitter for external Pt1000 probes with Cinch connector The transmitter measures the temperature from four external probes of the Pt1000/E line (the probe is not part of the instrument). Response to the jump temperature change is usually much faster than the models from the internal sensor.
- Page 16 W8810 Compact temperature and CO concentracion transmitter The transmitter measures the temperature and the concentration by a sensors located inside the transmitter box, which is equipped with vents at the top. The device is characterized by a simple compact design, but a relatively longer response to a step change of measured quantities than those with an external probe.

Page 17: Application Notes
Application notes Operation of transmitter in various applications ___________ Prior to commissioning, it is first necessary to assess whether its use is appropriate for the purpose, to determine its optimum setting and, if it is part of a larger measuring system, to prepare a metrological and functional control. - Page 18 Measurement of atmospheric pressure __________________ Models with atmospheric pressure measurement allow display on sea level pressure readings. In order for the conversion to be correct, you must, during device configure, enter the altitude at which the device will be located. Altitude can be entered either directly, in the form of altitude data, or indirectly, as an offset of absolute pressure.

Page 19: Operating And Maintenance Recommendations
A critically weak battery that can fail at any time is indicated by a blank battery symbol in the COMET cloud and flashing the empty battery symbol on the device display. Replace the battery as soon as possible. Note: When operating the transmitter at very low temperatures, the flashing of the blank battery symbol may not be on the sensor display visible. - Page 20 Check the seal integrity in the housing (if equipped) and reinstall the cover. Batteries can be purchased under their designation (SL2770/S) or, if purchased from the manufacturer (COMET SYSTEM, s.r.o.), under order code A4206. Service Recommendations ____________________________ Technical support and service are provided by the distributor of this device.

Page 21: Technical Parameters
Technical parameters Power supply The device is powered by one or two an internal lithium battery, accessible after unscrewing the cover (see the section How to replace the battery). Some models can also be powered from an external power source. The internal battery then serves as a backup source in case of external power failure. -
