LK 110 SmartComfort is an electronic weather compensated temperature controller for hydronic radiator and underfloor heating systems
Warning: Last items in stock!
Optional Pump Control and Room Temperature Unit with cable or wireless receiver. By measuring the supply and outdoor temperatures LK 110 SmartComfort regulates the mixing valve to provide the system with the exact amount of heat required in the building at any given time. The current supply and outdoor temperatures can be read on the controller display.
LK 110 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.

LK 110 SmartComfort is easy to install onto new as well as existing mixing valves. Mounting kits for installation onto mixing valves of other brands are available - see separate page.
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 - see under Accessories. 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.
Room temperature unit SmartComfort RT alternatively SmartComfort RTW is available as an accessory. For more information see product sheets for LK 120 and LK 130 SmartComfort.
