Functional Description
LK 100 SmartComfort CT
is an electronic constant temperature con-
troller for water supplied heat in radiators and underfl oor heating
systems. It can also be used for solid fuel boilers connected to an ac-
cumulator tank. The SmartComfort adjusts the mixing valve so that
the heating always has the supply temperature that has been set.
Installation, use and maintenance must be carried out by tech-
nical qualifi ed personnel. All instruction in this manual should
be observed and understood before starting any work with the
SmartComfort. For safety reasons no modifi cations or amend-
ments are allowed. Only original AC adapter is allowed.
Delivery Check
Check that the delivery includes the following components:
• Actuator
• Mounting kit (Fixation bolt, fi xing screw, lockwasher,
adapter)
• Knob with indicator
• Flow line sensor with 1 m cable
• AC adapter 100-240 VAC, 50/60 Hz with 1.8 m cable
• Cable
ties
Warning!
Risk of personal injury!
Before starting installation work disconnect power supply.
Make sure to adhere to valid safety regulations.
Installation of the Supply Sensor
Use the supplied cable ties to clamp the supply sensor on an uninsu-
lated part of the supply line aproximately 1 m after the mixing valve.
If necessary, thermal conductivity paste can be applied. The pipe then
must be insulated to obtain the best temperature measurement.
Connect the sensor cable to the notch marked
on the actuator.
Warning!
Risk of burns!
Avoid touching the hot supply line pipe when clamping
the supply sensor.

Installation
Installing the Actuator:
1. Turn the axle of the mixing valve A counterclockwise and re-
move the knob without changing the position of the axle.
2. Screw the fi xation bolt B in a suitable hole on the mixing valve A.
Remove possible 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 fi t in the
intended hole on the actuator.
4. Fit the knob E so that the indicator points to the counterclockwise
end position. Tighten the knob with the washer and the screw F.
5. Use a screwdriver to turn the decoupling screw G to the posi-
tion with hand symbol
. Turn the valve with the knob
E from one end position to the other. It is important that the
motor can be turned the whole turning angle (90°).
6. Connect the AC adapter to the connector marked
on
the actuator. Important! The AC adapter must never be ex-
posed to water.
7. Connect the cable from the supply sensor to the connector
marked
on the actuator.
8. Use a screwdriver to turn the decoupling screw G back to the
Automatic position
.
