1.5 Wireless sensors
Up to five wireless sensors can be connected to one
UltraLink using a smart device and the Lindab OneLink app. After successful pairing of a sensor, its readings are available both in the app but also in the registers where they are accessed under the following modbus registers:

Register| Reading|
---|---|---
3×2012| Presence| Sum
3×2021
3×2022
3×2023| Temperature| Min
Max
Average
3×2034| Airflow| Sum
3×2041
3×2042
3×2043| Humidity| Min
Max
Average
3×2051
3×2052
3×2053| CO2| Min
Max
Average

If you connect more than one sensor that reports the same variable type (for example two temperature sensors) then you can choose to read either the max, min or average value according to the table above.
1.6 Room regulation
The regulation will not strive to always reach a given set point. It will maintain the climate within the allowed deviation that is configured.
It can only maintain a climate where the supply air has the possibility to support it. It means that it can not give a lower temperature than the temperature in the supply air, if not connected to any cooling source.
The room regulation works by applying a multiplication factor to the normal flow.

As long as the regulation is within its deadband the regulation factor is 1.0. As soon as it move outside the deadband a multiplication factor is applied to the normal flow – meaning that the flow will increase. Before the system applies to the factor a check is automatically made to make sure that an increase of the flow actually improves the conditions. It will for example not increase the flow if the indoor temperature is too low and the supply air temperature is even l owe r.

1.7 Presence regulation

The multiplication factor from presence is always used when the room is unoccupied and it either overrides the other factors (Economy mode) or it is multiplied with the highest factor from the other regulation types (Comfort mode).
When the room is occupied its factor is treated just like the factor from temperature, CO2 and humidity and will only be used if it is the highest among the enabled regulation types.
The graph below (graph 1) shows the global set point factor that will be used in a case where regulation is active for all of the four regulation types mentioned above. Each regulation type is producing its own multiplication factor and at any given moment the highest of them will be used (as long as the room is occupied). The red areas shows the effect you get by activating Comfort mode.

Graph 1

1.8 Temperature, CO2 and humidity regulation

Each regulation type that is used for the room regulation will produce its own multiplication factor. The system will always be governed by the regulation type and the multiplication factor that demands the highest amount of air.

1.9 Signal for controling heating and cooling sources

Control of heating and cooling sources can be added using analog signals from the Ultralink. The signals on the analog ports AO1 and AO2 can be configured for heating and/ or cooling using the OneLink app. If heating and/or cooling is enabled on the analog ports, the same control curve that controls the temperature by air is used, but with one important difference. The max scale factor used to calculate the signal is always 100% and the minimum factor is 0%.
This means that the proportional regulation on the analog ports will always vary between 0-100%. The percentage is converted to the corresponding voltage level based on what type of control signal we have specified when configuring the analog ports (0-10V, 2-10V, 10-0V or 10-2V). The analog signals can be used for any passive heating or cooling source with an analoge actuator.

The UltraLink has a smart programming which prohibits both heating and cooling at the same time.
1.10 Airflow regulation
When regulation on airflow is used all other regulation types are deactivated. It can only be used alone. In this case the product will act as a slave to other airflow sensors of type FTMU or FTCU.

4.2 Temperature control

4.3 CO2 control

• Since the UltraLink has no CO2 measurement we need to add an estimated value to the supply air. This estimate will be the comparison to the value registered from the sensor in the room and will determine if the multiplication factor will be applied or not.
  Typical CO2 value for outdoor air is 400 ppm.

4.4 Relative humidity control

• Since the UltraLink has no relative humidity measurement we need to add an estimated value to the supply air. This estimatisation will be the comparesion to the value registered from the sensor in the room and will determine if the multiplication factor will be applied or not.

4.5 Presence control

4.6 Airflow control

• Set point calculation settings

Use summed airflow as set point| With this selection enabled the set point for the product will be calculated as the sum of the flows that are received as sensor data multiplied by the “Scale factor” and with “Flow offset” added.
New set point = (UltraLink sensor 1 + UltraLink sensor 2 +….) x Scale factor + Flow offset
---|---
Reduce products set point with summed airflow| With this selection enabled the set point that will be used corresponds to the products own set
point reduced by the summed flows that are received as sensor data multiplied by the “Scale
factor” and with “Flow offset” added.
New setpoint = (Setpoint – (UltraLink sensor 1 + UltraLink sensor 2….)) x Scale factor + Flow offset
Add summed airflow to products set point| With this selection enabled the set point that will be used corresponds to the products own set
point added with the summed flows that are received as sensor data multiplied by the “Scale
factor” and with “Flow offset” added.
New setpoint = (Setpoint +(UltraLink sensor 1 + UltraLink sensor 2….)) x Scale factor + Flow offset

Set UltraLink to control heating and cooling sources via analog signal

5.1 Run cable between UltraLink and heating/cooling source
5.1.1 Cut the power supply to the UltraLink.
5.1.2 Install analog actuator onto the heating/cooling source
5.1.3 Run cable between actuator and UltraLink AO1 or AO2

5.1.4 Restore the power supply to the UltraLink and turn it on.
5.2 Make settings to analog output signal inside OneLink app
5.2.1 Inside OneLink app; Go to “Configuration”.

5.2.2 Go to “Device settings”.

5.2.3 Go to “Setting of analog output AO1″/”AO2”

5.2.4 Click on “Variable” and select “cooling” or “heating”
If you are not able to select cooling or heating as analog output, you need to do a firmware update to your UltraLink. See “1.11 Firmware update” on page 5.

5.2.5 Click on “Voltage range” and select the voltage range according to the actuator.

To enable additional heating and/or cooling steering the following steps are also mandatory:

• Pairing temperatur sensor to supply UltraLink.

You can choose to read the room temperature via wireless sensor placed in the room, or via the extract UltraLink.
To read temperature via wireless room sensor, see paragraph (“3.1 Pairing of presence, temperature, relative humidity and/or CO2 sensor to supply UltraLink.” on page 7.
To read temperature via extract UltraLink, see paragraph: “3.2 Pairing UltraLink to UltraLink” on page 8.

• Enable room regulation via temperature, see paragraph: “4.2 Temperature control” on page 11

5.3 Disable increased airflow when heating/cooling
If your setup is based on disabling increased airflow when heating/cooling you need to set the “Max scale factor” for temperature control to 100%. By doing so, the temperature will be adjusted using only the heating/cooling source.

Give the end user control to adjust the room climate

The end user may control the room temperature via Lindab OneSet application.
To get access for controling the room the end user need to scan a QR-code connected to the room (generated from commissioning app OneLink).
6.1 Generate QR-codes associated to different rooms in the comissioning app OneLink™
The QR codes are generated in the commissioning app OneLink.
6.1.1 Go to “Configuration > Device info”

6.1.2 Go to “End user application access”

6.1.3 Fill in end-user permissions and generate QR code.
The QR code can be generated with different access per-missions (read only or read and write) and different duration of validity. This feature allows for flexibility and you can, for example, generate 24h codes for hotel rooms, but in a residential application you can generate codes that gives eternal access.

6.1.4 Save to phone gallery by clicking “Save to gallery”.

When everything is set up for use, download the end-user app OneSet for easy control of the temperature in the room.
The OneSet app can replace a traditional wall mounted room controller.

End-user app OneSet™

Ultra BT comes with an optional end-user app where it is possible to monitor the room and make some personal settings, for example room temperature. To be able to access the specific room control settings from this end-user app, you can easy scan the QR-code associated with the room you want to control.
The code is created via the commissioning application OneLink. See chapter “6.0 Give the end user control to adjust the room climate” on page 15

As soon as a QR-code is scanned, access- duration- and validity rights to the specific room is stored locally in the app. As long as you have right to access the room control settings, all stored rooms will appear in a list view in the OneSet end-user app. Access to these rooms can now be made without need of scanning the code again until the duration rights has exceeded. As soon as the duration is exceeded the room will be removed from the list view and you need to scan the code again to get new access.

Most of us spend the majority of our time indoors. Indoor climate is crucial to how we feel, how productive we are and if we stay healthy.
