Room control for underfloor heating

The heart and brain of your underfloor heating system

LK Room Thermostat provides the correct temperature in all rooms. The thermostat should be placed in all rooms, in order to "monitor" and communicate the heating needs of the room to the manifold's valve actuator. The room thermostats are available in several different design models and are available in wired or wireless design.

LK Room Temperature Control ICS.2

LK Room Temperature Control ICS.2 is a control system designed for LK Underfloor Heating. The system is suitable for small, medium or large building installations. LK ICS.2 has been designed to provide a high level of comfort and an energy efficient heating system due to its advanced self-modulation technology.

LK ICS.2 includes a variety of intelligent features, such as adaptive weekly programming, holiday functions, fire place functions, and an option to connect an external sensor. The adaptive function means the system learns when it needs to turn on underfloor heating to achieve the desired temperature at the right time.

By using the LK Webserver ICS.2 accessory, you can control your heating system via the Internet from a mobile phone, tablet or computer. LK ICS.2 can communicate using the Modbus protocol RS485/RTU for connecting to general building automation.

LK ICS.2 is easy to mount and, if possible, even easier to program.

Remote control heating and water with our app LK AtHome

Our LK AtHome app allows you to control and monitor your underfloor heating and water safety system via your mobile phone, tablet or computer. The app has a user-friendly interface that makes it easy to control and monitor all functions, for example raising or lowering the temperature or shutting off water remotely. If something goes wrong, the app will alert you by sending a push notice. Safe and secure.

LK AtHome is compatible with LK’s ICS.2 heating regulation system when the LK Webserver accessory is installed.

The system can also communicate using the Modbus protocol RS485 for connecting to general building automation.

Building automation

LK Room Temperature Control ICS.2 is suitable for both small, medium or larger building installations. LK ICS.2 has been designed to provide a high  level of comfort  and an energy efficient heating system due to its advanced self-modulation technology.

The system can also communicate using the Modbus protocol RS485 for connecting to general building automation.

Remote control

LK Room Temperature Control ICS.2 enables you to easily control the underfloor heating system in your house, summer or winter cottage even from a remote location. This saves energy when you are not there, at the same time as you can be sure that it is warm and pleasant when you arrive. Relax and enjoy your holiday when you can easily check that all is well in the house even when it is empty. By using the accessory LK Webserver ICS.2, you can easily remotely control your system from a mobile phone, tablet or computer. 

The user interface is simple and intuitive and offers a good overview of the underfloor heating system. It is easy to make all the system settings using this user interface.

LK RadControl

LK RadControl - Intelligent room control with water-heated radiators

LK RadControl - Intelligent room control with water-heated radiators

If you choose to heat a building using radiators, these can be controlled by an electronic room thermostat, located centrally within the room for optimum control.​

The LK RadControl concept is based on two of our best-known systems: LK ICS (intelligent room temperature control for underfloor heating) and LK Universal (a unique PE-X system for both heating and water). We have combined the best features from​ both these systems, enabling you to achieve intelligent room temperature control with hot water radiators.​

LK Room Temperature Control Basic S1 & S2

Room control BAS is a wired control system intended for LK Underfloor Heating. For best energy efficiency, the system works with so-called self-modulation technology. The self-modulation technology adapts the delivered floor heating effect in relation to the set temperature. As the room temperature approaches the set temperature, the delivered power is gradually reduced to avoid overtemperatures.

LK Rumstermostat S1

LK Room Thermostat S1

Room thermostat S1 has a traditional design but still in a modern look with a high-gloss white polished surface. The room thermostat is extremely thin and blends easily into the room's environment. Also available without knobs for public environments. 

LK Rumstermostat S2

LK Room Thermostat S2

Room thermostat S2 has a modern design with a high-gloss glassy surface with a touch setting of the temperature. The thermostat is also suitable in public buildings as the temperature settings can be locked by pressing a button combination.

Analyze your heating system

Here, users of LK Room Control ICS/ICS.2 can download the LK Analyzer ICS.2 software. Using this application, you can easily  monitor reading from LK Receiver ICS-W8, LK Receiver ICS-RF8 and the newer LK Receiver ICS.2. With the application installed, you can easily see the set target temperatures and actual temperatures for the various room thermostats.

Measurement data is logged using the LK ICS MEM memory stick, which is plugged into the receiver unit’s MEM port. Measurement data from the LK ICS MEM stick is then loaded into the analyzer application. Alternatively, if it is a later model of the receiver unit with the model designation ICS.2 and it has an LK Webserver ICS.2 connected, it is possible to load data into the analyzer application directly via a local network or through Internet.

Control room temperatures from your smartphone

LK Webserver can be used in conjunction with LK Room Control ICS.2 or LK Water Safety System to monitor and control temperatures remotely over Internet or LAN.

The user interface is designed for cell phones, tablets and computers and can be accessed at https://my.lk.nu or by installing the LK AtHome app , available for Android and Apple iOS. This update will allow access to the new interface on older webserver generation 1 (black) models. Download the instructions first, and then the installation file.
