Functional Description

LK 110, LK 120 and LK 130 SmartComfort are electronic tempe-
rature controllers for hydronic radiator and underfloor heating
applications. All models are equipped with frost protection and
minimum/maximum limitation of the supply temperature.
LK 110 and LK 130 are equipped with an outdoor sensor. The supply
temperature is adjusted according to the outdoor temperature.

Installation

Installing the Actuator:

1. Rotate the axle on the mixing valve A counterclockwise and re-
move the knob without changing the position of the axle.
2. Screw the fixation bolt B in a suitable hole on the mixing valve
A. Remove any existing bolt. Push the adapter C on the mixing
valve axle so that the axle bottoms in the hole. The supplied
adapter C suits most valve axles. Other versions of this adapter
are available as accessories. Please contact LK Armatur AB for
more information.
3. Fit the actuator D to the adapter C. The bolt B should fit in the
intended hole on the actuator.
4. Fit the knob E so that the indicator points to the counterclock-
wise end position. Tighten the knob with the washer and the
bolt F.
5. Use a screwdriver to turn the disengaging button G to the posi-
tion with hand symbol

. Turn the valve with the knob E
LK 120 and LK 130 are provided with a room controller. The
controller can be set to the desired room temperature. To
save energy, there are programmes that have scheduled
temperature changes.
LK 130 is equipped with an outdoor sensor, a supply sensor and
a room controller to optimize the control of the heating system.

from one end position to the other. It is important that the motor
can be turned the whole turning angle (90°).
6. Turn the decoupling screw G back to the Automatik position
