LK 130 SmartComfort is an electronic, weather compensated, indoor temperature controller for hydronic radiator and underfloor heating systems. By measuring the supply, outdoor and indoor temperatures LK 130 SmartComfort regulates the mixing valve to provide the system with the exact amount of heat required in the building at any given time.
Temperature controller LK 130 SmartComfort has an automatic choice of direction to adapt to the direction of the mixing valve. LED-indicators show if the controller is opening or closing the valve. The supply temperature can be limited with a minimum and a maximum value. Symbols on the controller show the chosen function and the LED display shows the setting or value of the function. Adjustments are easily made with the push buttons marked “+” and “- “.
Dependent on the dimension of the heating system and the insulation of the building, the heating curve may need to be adjusted in order to achieve the desired room temperature. The curve slope and the parallel displacement are easily adjustable with the push buttons.
Temperature controller LK 130 SmartComfort is delivered with a room temperature unit allowing easy setting of the desired indoor temperature.
The room temperature unit is available in two versions; with fixed cable SmartComfort RT or wireless receiver SmartComfort RTW. For further energy saving and increased comfort there are nine preset programs with scheduled temperature changes.
You can also create your own programs. Additional functions such as holiday and timer settings are available. The current outdoor temperature can be read on the room temperature unit.
The room temperature unit is adaptive which means that it memorizes, upon installation, how long it takes for the system to reach a desired temperature. This guarantees that the different temperature settings occur at the programmed time. After a temperature setback a booster function briefly increases the supply temperature in order to quickly reach the desired room temperature. Should the room temperature unit sense a sudden change in temperature, such as when airing a room, the unit disregards this change for the following half hour.
Temperature controller LK 130 SmartComfort is easy to install onto new as well as existing mixing valves.
The plug-in adapter provides quick and easy do-it-yourself installation. In case of a power outage the controller will keep its settings and the actuator will stop in its current position. By disengaging the controller, the mixing valve can be manually operated.
For further energy saving a pump control, SmartComfort PC, can easily be connected to the controller. SmartComfort PC stops the circulating pump
when no heat is required and exercises pump and mixing valve separately every two days, thus eliminating the risk of pump or mixing valve stalling after an intermission.
