ACTUATOR, FUNCTIONS AND SETTINGS

Indication
Above the knob on the actuator, there are two
indicators for hot (red) and cold (blue). At normal
operation, both indicators shine. If the angle of
rotation is changed, the indicator blinks in the
turning direction The blinking shifts to fixed
light shortly after the motion has stopped.
Temperature Display
The temperature can be displayed in °C or °F. The factory setting is
°C. To change temperature unit, press plus and minus buttons simul-
taneously for at least 3 sec.
Manual Operation
The actuator can be disengaged to allow manual operation of the
mixing valve. Turn the disengaging button 90° clockwise to the hand
position symbol . The symbol will now start flashing.
Automatic Selection of Direction
Adaption to mixing valves with different opening directions is done by
an actuator test to determine if the valve opens clockwise or counter-
clockwise. The test takes some minutes and occurs at first startup.
The actuator selects and saves the opening direction. Automatic selec-
tion of only works when there is heat in the system. If the automation
cannot decide direction, a manual choice should be made.
Manual Selection of Direction
Check the opening direction of the mixing valve. Adapt the opening
direction of the actuator in the following way:
Clockwise direction: Push the plus button
the actuator. The display counts down 3-2-1. Let go of the plus button.
The direction is indicated by a red light to the right on the actuator. The
automation selects clockwise direction and the indication switches to
fixed light.
Counter-clockwise direction: Push the minus button
power up the actuator. The display counts down 3-2-1. Let go of the
minus button. The direction is indicated by a red light to the left on
the actuator. The automation selects counter-clockwise direction
and the indication switches to fixed light.
Min. Temperature (Antifreeze)
The working range of the actuator can be limited to prevent the tem-
perature from falling below a set value (provided that there is heat in
the system). Step to the symbol for min. temperature by using the
function selector. Increase or decrease the value by using the plus or
minus button. The min-value cannot be set above the max- value. The
max-value will automatically increase as soon as the min-value reaches
the max-value. The max-symbol will flash to indicate that the tem-
perature setting has been changed.
Max. Temperature
The working range of the actuator can be limted to prevent the tem-
perature from rising above a set value. Step to the symbol for max. tem-
perature by using the function selector. Increase or decrease the value
by using the plus or minus button. The max-value cannot be set below
the min -value. The min-value automatically decreases as soon as the
max-value reaches the min-value. The min-symbol
cate that the temperature setting has been changed.
This temperature limitation can be used e.g. to protect sensitive
building structures such as wooden floors with underfloor heating.

Curve Control
For model LK 110 and LK 130. This operation converts the meas-
indicators
ured outdoor temperature to an internal setpoint with the help of
a curve control. The curve must be adjusted and parallel shifted to
match different buildings and the operation of the heating system.
In model LK 130, the setpoint is also affected by the difference between
the indoor temperature (measured by the room controller) and the
setpoint in the room controller (the desired room temperature).
Curve Setting
For model LK 110 and LK 130. The curve can be adjusted from
1.0 to 9.9. Step to the symbol for curve
selector. Increase or decrease the slope of the curve with the plus
or minus button.

Parallel shift of the Curve
For model LK 110 and LK 130. With the parallel shift of the
curve the flow line temperature can be changed +-10°C/+-18°F.
To change the room temperature by 1°C, the supply temperature
should be changed 2 - 4°C. Step to the symbol for parallelshift
by using the function selector. Change the position of the curve
with the plus or minus button.
Reset to Factory Settings
Press the plus and minus buttons simultaneously during power-up.
The display counts 0-9-8-7-6-5-4-3-2-1-0. Let go of the buttons.
