Lindab UltraLink Heating and Cooling Control Instruction Manual

Lindab UltraLink Heating and Cooling Control Instruction Manual

Function overview

Introduction

The heating and cooling feature is accessible from Linda Ultra Links type ≥4.
You can read the type number on the Ultra Link product label.

This commissioning instruction describes the functionality and commissioning steps of the heating- and/or cooling feature where you can control your heating and cooling sources from the registered values of an Ultra Link.

The configuration is done in Linda One Link application via a smart device.

Feature description

By reading the temperature of the extract air or the room temperature via a wireless sensor, this feature will enable your Ultra Link to control your heating and/or cooling sources via analog output signals. The signals on the analog ports AO1 and AO2 will be configured for heating and/or cooling from the OneLink app.

When heating and/or cooling feature is enabled on the analog ports, the control curve that control the temperature by air will convert the max scale factor to 100% and the minimum factor to 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 and/or cooling source with an analoge actuator.
The Ultra Link has a smart programming which prohibits both heating and cooling at the same time.

Commissioning application – Linda One Link™

Wireless sensors

Up to five wireless sensors can be connected to one Ultra Link using a smart device and the Linda One Link 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|
---|---|---
3×2021| Temperature| Min
3×2022| Max
3×2023| 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.

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 lower.

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, e.g. Lindab APR 40405.

Ultra Link to Ultra Link as temperature sensor or slave unit

If you wish to use the extract Ultra Link as temperature sensor to the supply Ultra Link, you need to pair the extract Ultra Link to the supply Ultra Link.

To complete the commissioning of the heating and cooling control function we recommend to also pair the supply Ultra Link to the extract Ultra Link so that the extract Ultra Link acts as slave unit to the supply Ultra Link.

The steps in this paragraph describes the pairing steps.

Open One Link application.

Scan for devices and connect to your Ultra Link.

When pairing extract Ultra Link to supply Ultra Link as temperature sensor – connect to the extract Ultra Link in this step.
If pairing extract Ultra Link to extract Ultra link as slave – connect to the supply Ultra Link in this step.

**Copy the Ultra Link MAC address.

Disconnect Ultra Link.
**

Scan for devices again and connect to the other Ultra Link.

When pairing extract Ultra Link to supply Ultra Link as temperature sensor – connect to the supply Ultra Link in this step.
If pairing extract Ultra Link to extract Ultra link as slave – connect to the extract Ultra Link in this step.

Go to “Configuration”.

Go to “Wireless sensors”.

**Tap on one of the available (grey colored) sensor slots.

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 Ultra Link. See “1.7 Firmware update” on page 4.

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 temperature sensor to supply Ultra Link.

You can choose to read the room temperature via wireless sensor placed in the room, or via the extract Ultra Link.

To read temperature via wireless room sensor, see paragraph (“2.1 Wireless temperature sensor to supply Ultra Link.” on page 5.

To read temperature via extract Ultra Link, see paragraph: “ 2.2 Ultra Link to Ultra Link as temperature sensor or slave unit” on page 6.

• Enable room regulation via temperature, see paragraph: “ 3.2 Temperature control” on page 9

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.
