Technical specifications
T-Valve is a smart LoRaWAN® water valve used in residential or commercial buildings. 3/4″ and 1″1/4 versions available, certified for Drinking Water. It has 10 years of battery life calculated with daily on/offs. It also measures water and environment temperature. It has multiple tamper protection mechanisms – tracking magnetic interference and if the device is being physically abused. Optionally a wired flood sensor and external power supply can be installed. T-Valve gives you the opportunity to stop potential water damage from happening, by being able to control the main water supply in your property from a distance. No more floods and damages.

Device operating voltage: 2.7 – 3.6VDC
Device parts
Commissioning
-
Open your LoRaWAN® Network provider access panel and add the device using the supplied Serial Number, DevEUI, AppEUI (JoinEUI) and AppKey.
**** The data is example. Do not use. -
Continue the Installation with the instructions of your LoRaWAN® Network provider.
You can get DevEUI, AppEUI (JoinEUI) & AppKey information from the LoRaWAN® credentials .csv file we sent you with the fulfillment confirmation. -
Out of the factory, T-Valve comes in deep-sleep mode and it has to be initially activated in order to start normal operation. In deep-sleep mode the device is not transmitting or receiving any data in order to preserve the battery before being installed.
In order to activate T-Valve, press the OK button 5 times quickly.
-
If T-Valve is NOT connected to a network, when one presses the OK button, an alternating animation of the Flood, Leak, CLOSE & OPEN LEDs will be shown. Once the device has received Join Accept from the LoRaWAN® Network, it will not show the above-described animation. Instead, if one presses the OK button, the LED of the corresponding valve state will be activated shortly – e.g. OPEN LED or CLOSE LED.
LEDs and behaviour
On the side, you can see an illustration of T-Valve’s LEDs and buttons. The LEDs have the following purpose:
| # | Name | Purpose |
|---|---|---|
| 1 | OPEN | Activates when one presses the OPEN button or the OK button and the |
valve is currently open.
2| CLOSE| Activates when one presses the CLOSE button or the OK button and the
valve is currently closed.
3| Leak| Activated through a downlink command indicating the customer there’s
a small leakage detected in the system. T-Valve DOES NOT detect small leakages
itself.
4| Flood| Activated in case a wired flood sensor is installed and a flood is
detected.
Warning: Opening and closing the valve uses a lot of current. If you press the buttons OPEN and CLOSE fast consecutively, T-Valve may indicate that there’s not enough to perform the desired action. Inside, a large capacitor is charged, which takes approx 1s to recharge. If you try to OPEN or CLOSE the T-Valve and this capacitor is not yet fully charged, the OPEN or CLOSE LED will blink 3 times.
Optional installation of external accessories
T-Valve offers optional installation of a wired flood sensor, which can close
the water supply immediately after sensing a flood. T-Valve also offers
optional external power supply installation. The power supply DOES NOT charge
the battery inside T-Valve. In order to install an accessory, you will need
an appropriately IP-rated cable-gland, which can be supplied by MClimate.
In order to install a cable-gland, one has to first press with a screw-driver
the openings on the bottom of T-Valve and remove the excess plastic. Whichever
cut-hole can be used for the installation of the cable-gland. If required, two
cable-glands can be used. 
In order to install the cable-gland, one must disassemble the device using the four Phillips screws. If the device is connected to a network, the anti-tamper protection will be activated and the device will signal in the uplink that the device is opened.
Optional installation of external accessories
a. Installation of a wired flood sensor
The wired flood sensor can detect whether a cable is broken or cut. Feed the
connector through the cable-gland and install it on T-Valve PCB as described
in the picture below.
Optional installation of external accessories
a. Installation of external power supply
The external power supply is also fed through a cable-gland and installed on
the T-Valve PCB according to the picture below.
Pwr and GND pins from P10 connector.
Pwr pin voltage range: 5-9Vdc
