User Interface The device has one LED in the upper right corner to communicate with the user. To interact with the device a magnet switch is present inside the product. To use this switch the user must be in possession of a Magnet Key which should be placed as instructed below. The Magnet Key can be held in position for different actions in the process. Magnet Key The Magnet Key is a magnet that can be used to: 1. 2.
During calibration / resetting of the calibration: ● ● ● Blue → user action required YellowUncalibrated (steady) → measuring / wait… (keep magnet away from the device) Calibrated Yellow (blinking) → connecting / wait… User action required Uncalibrated Measuring / wait... Calibrated Connecting / wait... Fig. 6: User action required Fig. 7: Measuring / wait... Fig. 8: Connecting / wait... When Operational: Open The handle is turned to the open position (greater than 2.
Troubleshooting When the device is being calibrated or when the device is operational, in exceptional cases certain steps in the process might not succeed. When the device is successfully connected to the network and problems occur, the troubleshooting should be performed on the network side. The device is working correctly. Time-out A time-out is a time limit for the completion of a certain process step.
Device State The device state tells the user if it is calibrated or not. This can be recalled using the magnet key. Request the device state 1. Tap the magnet key on the indicators of the device (Fig. 3 Page 4) ● Red → uncalibrated OR ● Green → calibrated Shut Open Tap Magnet Key Shut Shut Open Open Calibrated Uncalibrated Fig.11: Request the device state 7 TWTG R&D B.V. 2019 V1.
Calibrating the device 1.1 To ensure an accurate measurement, the device needs to be calibrated correctly. This process contains 4 steps: 1. 2. 3. 4. Shut valve Hold magnet → device state → hold magnet for 4 more seconds → connecting to the network → measure shut valve Open valve → tap magnet key → measure open valve Shut valve → tap magnet key → measure shut valve → connecting to the network → calibrated Shut Open Shut valve Step 1: Shut valve 1. Completely shut the valve Fig.
2. Keep holding the magnet key for 4 more seconds ● Yellow (blinking) - connecting / wait… (max. 2 min.) ● ● Yellow (steady) - measuring / wait…(max. 30 s) (keep the magnet key away from the device) ● ● Red → connection failed / time-out → uncalibrated → check network Red → measurement failed / time-out → uncalibrated → go back to step 1 Blue → user action required (max. 30 s) → go to step 3 ● Red → time-out → uncalibrated → go back to step 1 2.
Step 3: Open & measure 3.1 1. Open the valve by turning the handle more than 2.5 degrees 2. Tell the device that the valve is opened by tapping the magnet key Shut Open Open valve ● Yellow (steady) - measuring / wait…(max. 30 s) (keep the magnet key away from the device) ● ● Red → measurement failed / time-out → uncalibrated → go back to step 1 Blue → user action required (max. 30 s) → go to step 4 ● Red → time-out → uncalibrated → go back to step 1 3.2 Shut > 2,5° Fig.
Step 4: Shut, measure & send 4.1 1. Completely shut the valve 2. Tell the device that the valve is shut by tapping the magnet key ● Yellow (steady) - measuring / wait…(max. 30 s) 4.2 User action required Red → measurement failed / time-out→ uncalibrated → go back to step 1 Yellow (blinking) - connecting / wait… (max. 2 min.) ● ● Open (keep the magnet key away from the device) ● ● Shut Red → connection failed / time-out → uncalibrated → go back to step 1 Fig.
Resetting the calibration In some cases it might be necessary to reset the calibration of the device: 1. 2. 3. When the device is being reinstalled, relocated or removed When the network has changed When the device does not work correctly Procedure 1. Hold the magnet key on the indicators of the device (Fig. 3 Page 4) and keep holding it, after 1 second the device will show its state ● Green → calibrated → keep holding the magnet key and go to step 2 ● 2.

General notes for installation 1. 2. For accurate temperature reading both the sensor and the object it is installed on need to be insulated. The sensor measures the temperature of the outside surface it is installed on. The relation to the inside temperature is installation and content dependent. Installation options Installation is divided in two options: 1. Installation without adhesive 2.
Installation without adhesive The Temperature Sensor may be placed without adhesive when: • • The device is mounted behind insulation The mounting surface is sufficiently magnetic Necessities • • • • Sandpaper / Putty Knife Cleaning Supplies Temperature Sensor Magnet Key (P18-023-M_KEY) Sequence 1. If the surface is not smooth remove any irregularities using a putty knife or sandpaper 2. Clean the surface - make sure dirt and grease is removed 3.
5. The Temperature Probe should make full contact with the surface, if this is not the case repeat step 1 and 2 Contact A DETAIL A Fig. 14: Temperature Probe Contact 6. Replace original insulation 11 TWTG R&D B.V. 2019 V1.
Installation with adhesive The Temperature Sensor must be placed with adhesive: • • Mounting surface is not sufficiently magnetic When the product is installed at 2m or higher above ground level, the adhesive should always be used Necessities • • • • • Sandpaper / Putty Knife Cleaning Supplies Temperature Sensor Adhesive Magnet Key (P18-023-M_KEY) Sequence 1. If the surface is not smooth remove any irregularities using a putty knife or sandpaper 2.
4. Turn on the Temperature Sensor (see chapter “User Interface”) 5. Mount the Temperature Sensor using the adhesive and the internal magnets 6. The Temperature Probe should make full contact with the surface, if this is not the case repeat step 1 and 2 Contact B DETAIL B Fig. 16: Temperature Probe Contact 7. 13 Replace original insulation TWTG R&D B.V. 2019 V1.
