• Temperature controller

• Adapter 24 VDC

• Mounting kit for mixing valve

• Supply temperature sensor with 1 m cable

LK SmartComfort is an electronic controller that 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. LED-indicators show

if the controller is opening or closing the valve. Adjustments

are easily made with the push buttons marked “+” and “- “. The

selected value will be shown on the LED-display.

LK 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.
