Novasina nSens probe. The probe is not included. Page 10. The available radio modules are: FT10-RT433 Radio transmitter for Nokeval’s 433 MHz “MTR series”. The combined product is named Flex- RT433-T for example. Details on page 11. Ovazone-Flex- Radio transceiver for 2.4 GHz mesh known as Radio or “Ovanet”, “Ovazone”, or “Zone”. - Page 5 The wireless settings are stored and retained in the radio module. Exchanging the measurement module does not affect them, which allows easily exchanging the measurement module to a recalibrated unit, especially with the T and T-RH models. Also some of the other settings are stored in the radio module, e.g.

Page 6: Installation
Installation Opening the measurement module Opening the module is necessary only for replacing the battery and for wiring the internal connector on the ES model. • Detach the measurement module from the radio module. • Use a large flat-bladed screwdriver to push the measurement module cover off via the rectangular hole (see picture). -

2. Detach the modules. 3. Connect a Nokeval DCS772 programming cable to the 3.5 mm jack in the measurement module. 4. Launch the Nokeval Mekuwin software (freely downloadable from http://www.nokeval.com/). Select your DCS772 from the list, then select Protocol=SCL, Baud=9600, Address=0, and click Direct. -

Page 9: Flex-Cs And Flex-Es Modules
Flex-CS and Flex-ES modules Wiring In the CS model, the RTD sensor is connected to the M12 connector. The module has a female connector. A compatible male plug with screw terminals is supplied. The plug has small terminal numbers. A 4-wire sensor should be used, connect its one end to terminals 1 and 2, and the other end to 3 and 4. -
Page 10: Flex-Nsens Module
Flex-nSens module Sensor probe The measurement module accepts a Novasina nSens-HT-ENS or an nSens-HT-CSS humidity and temperature probe. For that, the measurement module has a three-pole female connector. The Novasina probe can be attached directly to the measurement module, or an up to 2 m extension cable used in between. -
Page 11: Ft10-Rt433 Radio Module
The FT10-RT433 radio module has been originally designed for the FT10 series (e.g. FT10-RT433-IS transmitter) but it can be used in the Flex series too (since firmware 2.0). It allows using the Flex measurement modules with the Nokeval MTR wireless series devices, e.g. the RTR970 receiver, the FT20-RTC433-RECEIVER, and Ovazone-Wave-Link-MTR gateway. -
Page 12: Flex-Zone-Radio Module
About the wireless technology Ovanet is Nokeval’s second generation radio network. It uses Wirepas Connectivity technology and Nokeval’s own additions. It utilizes the 2.4-2.48 GHz band, which is available all over the world. The product names basically begin with the Ovazone prefix. - Page 13 Furthermore, if another radio module is connected to the measurement module, the measurement module will read the wireless settings to its memory so that they are visible in the configuration menu on the next Mekuwin session. Network: This setting determines the Ovanet network address. It must be the same on all the radio devices including the gateway device.

The Sky devices use the Semtech LoRa modulation technique that allows unforeseen wireless range in a battery powered transmitter. The protocol used is defined by Nokeval, called NLORA1, which means that the Sky devices are not compatible with the LoRaWAN infrastructure. - Page 15 Effort Bandwidth Spreading Estimated indoor range Estimated outdoor setting factor 40...35 dB/decade range 30 dB/decade 250 kHz 110...310 m 1300 m 250 kHz 120...370 m 1600 m 250 kHz 140...440 m 2000 m 250 kHz 160...520 m 2400 m 250 kHz 190...610 m 2900 m 250 kHz...

Normally the recalibration includes replacing the battery. The calibration certificate for the measurement module can be downloaded from www.nokeval.com. The nSens model is an exception. As the calibration data is stored in the nSens probe, it is sufficient to recalibrate the probe only. -
