Detailed view of a ThermoValve thermostat

General

Model

The model of the ThermoValve thermostat.

Device EUI

The device EUI is used to uniquely identify the device. You can also find the device EUI on the label on the back of the device.

Last Connection

Indicates when the device last connected to the Avelon server.

Activation Date

The date the device was registered on the system.

Energy Harvesting

Indicates whether energy harvesting is currently active. Thermoelectric energy harvesting converts heat flow created by a temperature difference into electrical energy, which can be used to power the device.

LoRaWAN

LoRaWAN Network Provider

Indicates which LoRaWAN network provider the device is currently registered with. To learn how to change your network provider, see LoRaWAN network provider.

Application EUI

The EUI of the application on the LoRaWAN server to which this device is assigned. Only available if the device is self-managed.

Application Key

The key of the application on the LoRaWAN server to which this device is assigned. Only available if the device is self-managed.

Application ID

The ID of the application on the LoRaWAN server to which this device is assigned.

Allow access to this device in the public web app without login

If you want to use the QR code on the device to quickly access its measurements, keep this option enabled. However, this will make the device accessible on iot.avelon.cloud to anyone who has access to the QR code. If you deactivate the option, the device and its measurements can only be accessed when you’re logged in. You can change this setting at any time.

Location

Address

The location address of the device. If you fill in this field, the device will be displayed on the map widget and in the map navigation.

GPS

If the address input above is insufficient, you can also specify the location of the device using GPS coordinates.

Configuration

Set Point Temperature

The set point temperature to which the thermostat should regulate the room temperature. Also see Data points below.

Flow Sensor Compensation Offset

Due to thermal transitions, an offset occurs between the flow sensor installed in the thermostat and the actual temperature in the water circuit. This offset is compensated by the automatic offset correction function in the thermostat. The temperature control circuit input value is therefore the flow sensor value corrected by the respective offset. You can change the default offset (+ 5°C) here.

Radio Communication Interval

Configure how frequently the thermostat should send messages.

Use Temperature Data Point From

Even though the thermostat has an integrated ambient sensor, it is strongly recommended to always use an external temperature sensor to measure the room temperature, because the integrated sensor is influenced by self-heating of the metallic device housing during heating operation.

You can assign a Wisely room sensor or a My LoRa Device to your ThermoValve thermostat as an external temperature sensor. The external sensor will measure the room temperature and send it to the ThermoValve thermostat via LoRaWAN, which will use this value instead of the one from its internal ambient sensor. The same external sensor can be assigned to multiple ThermoValve thermostats.

For Wisely sensors, the room temperature will be linked to ThermoValve automatically. For My LoRa Devices, you have to make sure that the key of the temperature data point on its respective IoT profile is set to temperature, so that the ThermoValve knows which data point of the LoRa device corresponds to the room temperature.

Warning

If a Beetle has been assigned to the ThermoValve thermostat as its LoRaWAN network provider, the external sensor has to be assigned to the same Beetle.

Drop Detection

Devices with firmware version 2.4 or newer have an option to detect temperature drops and temporarily close the valve. Note that the Radio Communication Interval of the device must be set to 5 or 10 minutes for the drop detection to work properly.

Action Upon Temperature Drop

• None

• Close valve for 30 minutes

• Close valve for 60 minutes

Depending on your selection, the valve will be closed for the specified amount of time if the device detects a temperature drop of more than 1.5 °C within 10 minutes. After the specified time period, the device will resume normal operation.

Required Consecutive Temperature Drops

You can specify whether a drop should be reported right away after one temperature drop, or only after two consecutive temperature drops.

Select the option Beep upon resuming normal operation if you want the device to emit an acoustic signal when the valve is reopened after a temperature drop.

Device access

Here you configure which user groups are allowed to access the device and its data points. If users should see data points or their recordings or live values, they need to have access to the respective device on which these data points are located.

To add a user group, click on Add User Group and select a user group from the list. All users in that user group will get access to the device. To remove a user group, click on Remove next to the corresponding user group.

Granting access to a device also enables access to the device via our public API.

Note that users with the action right “Show all devices” can see all devices of the client, regardless of their respective user groups.

Data points

The data points of the device are displayed on the Data Points card, but they can also be found on the Data Points and Filters tab at the top.

Communication failure

Indicates whether the system received an uplink message from the device within the given communication interval.

Ambient temperature

The room temperature measured by the thermotat directly.

Battery

The battery capacity of the thermostat.

Device failure

Indicates whether there are issues with the Thermostat:

• Motor error

• Flow sensor failure

• Ambient sensor failure

• Device is in mounting position and turned off

Flow temperature

The average flow temperature over 30 minutes. This includes the offset configured in Flow Sensor Compensation Offset.

Room temperature

The room temperature that was measured by a Wisely and sent to the thermostat.

Set point temperature, written

The set point temperature that was set by the user. This can either be set manually in the field Set Point Temperature in the card Configuration above, or you can create a surrogate BACnet object to set it via a BACnet schedule.

Set point temperature, recorded

The set point temperature that is currently configured on the device.

Valve position

The current position of the valve in percent.

Alerting

Enable Watchdog

Activate the watchdog to be notified if the device does not report in for a longer period of time. This allows you to react in time in the event of a device defect or insufficient transmission power. Select the desired alarm chain from the dropdown.

Warning

Watchdog alarm tickets cannot be closed until the device sends an acknowledgment that the alarm is gone and that the connection with the server is reestablished. As a result, when trying to close a ticket prior to device acknowledgment, the following error message is displayed: “This ticket cannot be closed. The alarm must be acknowledged by the device first”.

Enable Battery Alarm

Activate the battery alarm to be notified if the battery falls below a certain threshold. Select the desired alarm chain from the dropdown.

Write set point temperature via BACnet

It is possible to create a surrogate BACnet object for the set point temperature, which can then be written to via BACnet. This gives you finer control over your set point temperature, and you can use a BACnet schedule to set your set point temperature.

To set this up, you need to assign a Beetle as the LoRaWAN network provider of your ThermoValve thermostat.

Note

Note that the following licenses are required on your Beetle to support this feature:

• BACnet/IP

• IoT (LoRaWAN Server)

1. On the configuration page of your ThermoValve thermostat, click on More ▸ Configure LoRaWAN Network Provider.

2. On the following dialog, select Beetle in the dropdown LoRaWAN Network Provider.

3. In the dropdown Beetle, select the Beetle that you want to assign to the ThermoValve thermostat.

4. Make sure that the option Create Surrogate BACnet Objects is enabled.

5. Confirm the dialog with OK.

New BACnet objects will be created for the data points of the ThermoValve thermostat and added to the Beetle. You can use the BACnet object Set Point Temperature, written in your BACnet schedules.

In order to use the set point temperature on your schematic, you need to reconcile the BACnet object and place the reconciled data point.

Schematic link

It is possible to jump directly from the IoT app, which you can open via the QR code of one of our IoT devices, to a specific schematic, for example to control the parameters of the air conditioning system. You can specify which schematic is to be opened under Schematic Link.

If you also select a data point filter, the system will try to dynamically fill the data points on the schematic using this data point filter. However, this only works if the system names in the shapes used are set in such a way that a unique assignment of data points from the selected data point filter to the shape is possible.

As soon as the link is set up, a corresponding link to the schematic appears on the IoT app.
