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 Installation, commissioning and maintenance must only be carried out by a qualified person in accordance with applicable regulations and standards. Mounting For the optimum operation of the Wx8xxP Series, it is necessary to ensure their vertical position. Models without external probes or sensors may loosely stand on their bottom base as required, other... - 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: •...

Cloud is an internet storage of data. You need a PC with internet connection and a web browser to work with. Navigate to the cloud address you use and sign in to your account - if you use COMET Cloud by a transmitter manufacturer, enter www.cometsystem.cloud... - Page 10 The function can only be used once every 24 hours. If you use COMET Cloud and you want to be informed about the change of alarm status, eg by e-mail, it is necessary to set at least one alarm profile correctly.

Page 11: Alarm Functions
Alarm functions The transmitter sends the measured values in regular messages, according to the set sending interval. In addition, the transmitter can also send extraordinary alarm messages when a new alarm is generated on a tracked channel or the alarm in progress is extinguished. This feature allows you to extend the battery life by setting a longer sending interval for regular messages, and the user is informed about changes in the alarm status by extraordinary messages according to the current situation. - Page 12 After a new alarm is triggered, an extraordinary alarm message is sent within 10 minutes at the latest. Temporary interruption of the current alarm (max. 10 min) is not indicated. After ended of alarm, an extraordinary alarm message is sent within 10 minutes at the latest. (A) regular message sent in sending interval (B) extraordinary message - start of alarm (C) extraordinary message - end alarm...

Page 13: Manufactured Models
Manufactured models COMET's Wx8xxP transmitters differ in the type of measured quantities (temperature, relative humidity, DC voltage) 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 battery. - Page 14 (indication of wind gusts, maximum minut electrocity consuption…). The obtained counter values can be recalculated in COMET Cloud according to the entered conversion relation and displayed directly in the values of the measured quantity.
- Page 15 The input can also be used to connect sensors of various quantities with a standard output, eg 0-10 V. In the COMET Cloud (after entering the conversion relationship) the measured voltage signal is recalculated and displayed directly in the values of the measured quantity.
- Page 16 Digi/E probes The transmitter measures the temperature, relative humidity and dew point temperature from the COMET Digi/E external probe (the probe is not part of the instrument). Response to jump-change of temperature and relative humidity is significantly faster than models with internal sensor.

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 Problems with measurement accuracy ___________________ Incorrect measured values of temperature and relative humidity are most often caused by inadequate probe position or measurement methodology. Some notes on this issue are listed in the chapter Operation of transmitter in various applications. Another group of problems are random peaks in the measured values.

In this case, it is not necessary to change the battery. A critically weak battery that can fail at any time is indicated by a blank battery symbol in the COMET cloud and on the front panel of the device by double flashing of the LED with an interval of 10 s. - Page 20 Make sure that the seal in the cover groove is clean. Carefully tighten the cover of the device. The batteries can be purchased under their designation (SL2770/S) or, if purchased from the device manufacturer (COMET SYSTEM, s.r.o.), under order code A4206. Service Recommendations ____________________________ Technical support and service are provided by the distributor of this device.
