Most technical installations need room sensors to operate optimally for the users. We have a broad range of sensors for ModBus installations. E.g. our standard white ModBus sensor 70x70 cm 30mm deep for measuring either temperature and CO2 or temperature, CO2 and humidity.

However, many users do not like the sensor to be that visible. Therefore, we have developed a new very flat sensor in a discreet white design, only 10mm deep, making it almost invisible on the wall. This new flat sensor is completely maintenance free and can be mounted in a standard wall box or with a wall bracket. It comes in 2 variations, 1 measuring temperature and humidity and 1 measuring temperature, humidity and CO2.

Finally we have a range of sensors for installations where wiring is not optimal. Our range of ModBus Wireless Sensors uses standard Alkaline 1.5V AA batteries and with their low voltage use the batteries last up to 2 years. The signal range in normal circumstances is 75-100m and it is possible to setup up to 16 sensors in one network.

PressureBox is much more than just a versatile pressure sensor equipped with 1 or 2 pressure sensors and available in various pressure areas.

If you want to measure flow instead of pressure, you simply enter the K-factor into the PressureBox.

And by setting an internal setpoint he PressureBox can be used as a simple VAV/CAV controller.

You may use the PressureBox to just read out the measured pressure. It can be read through the 0-10V output signal or via ModBus protocol.

However, if you use the ModBus protocol, the PressureBox can be used as compilation point for 2 temperature sensors (NTC or PT1000) and digital inputs such as filter guard etc. All readable through Modbus.

Furthermore, PressureBox is available both with and without display.

We have displays and operating panels for both built-in and wall mounting. All for ModBus communication.

The traditional way of having displays is horizontal. For these configurations we offer both 4” and 7” high resolution graphical displays with either resistive or capacitive touch.
Resistive touch is highly recommended for environments where operation is carried out with tools or gloves on. Furthermore, the foil over the display ensures a seal of IP54 or more can be obtained.

A more modern way to look at a display is having a vertical display with the feel and orientation of your mobile phone. The vertical display makes it possible to have the same design as if it was an app on a mobile. And with our 4.3” vertical display you will experience a fast graphical display with an incredible performance. The graphical interfaced used gives an endless number of possibilities to the design the graphic exactly to your wishes.
Furthermore this display is very flat, only 10mm deep and can be mounted in a standard European wall box or built-in your product.

If these displays are a little too big for your configuration, we also have a small 2.8” flat graphical display. This display comes with a glass panel and in principle it has the same possibilities as the larger 4.3” vertical display. However, the smaller size must be considered when designing the user interface.

Sometimes a graphical display / operating panel is a too advanced or expensive user interface for a product. For those products / configurations we have developed an operating panel in the same slim design as the 4.3” and 2.8” display, only 10mm thick. The oprating panel can be mounted in a standard European wall box, built-in the product or mounted on the wall with a wall bracket. The user interface can consist of up to 6 touch “buttons” and LCD indicators.

The TopBox is a ModBus Controller especially designed for fans in groups and grids.

It is very suitable for retrofit of ventilation, where efficiency is improved by installing modern ventilators.

TopBox is equipped with 2 separate ModBus outlets. One can be used for controlling e.g. a group of air supply fans and the other one for controlling a group of air extraction fans.

Technically TopBox receives a signal from an existing controller, either ModBus signal or 0-10V signals, which converts to ModBus controlling of ventilators / fans in groups. Also, a feature of regulation by signal from a pressure transducer is available. This control by pressure can be combined with calendar and outdoor temperature compensation.

Monitoring the operation can be done in LS Config app, by connecting a display to the TopBox or by choosing TopBox with built-in display. Also, it can be done in the BMS / CTS if such is part of the installation.

TopBox can be connected to the internet using LAN connection and thereby get access to LS SmartConnect Center.

Setup is easily done using the Bluetooth connection to access our LS Config app which is included in the product.

With LS Config App you get a service tool for technicians and a user app for the end-user at the same time.

The LS Config App consist of a base platform which is easily adapted to the requirements of most product configurations including colors, style, menu options and values. It is a data base driven app, meaning that updates including logo, colors and functionalities are updated right in the app without the user having to reinstall the app.

Let us worry about Apple and Google requirements and updates and share the cost for keeping the app in compliance and get new functionalities automatic.

How Does It Work?
To use the app to control o setup a product, the product needs to be connected to the app. The connection is very simple, just scan the QR-code on the product. The app then collect all functions for that particular product and present it as designed in the app. The product can be controlled and current status be read in the user-friendly app, as long as you are within Bluetooth range.

What Are the Options Within the App?
Which options the end-user have to control the product is completely up to you as manufacturer of the product. And the possibilities are many. E.g. adjusting set points, set calendar for different operation on different days and times, enable holiday function, update firmware etc. etc.

However, you may choose that some options should only be allowed to be performed by a service technician, Those options can be hidden behind a pasword protection, or maybe need login - it is all up to you.
