Description
Selectable value
FORCE HEAT
Used to force the snow melting to start. Snow melting is
activated for the time given under the heading
Afterrun
.
Select ON or OFF.
SELECT SCALE
Indicates the temperature scale to be used
Select C or F.
SET TEMP 1
For the unit to start, the temperature must be below the
given value. (The value refers to ground sensor 1.)
Select between -20 - + 50 ºC.
D 3 ºC
SET TEMP 2
For the unit to start, the temperature must be below the
given value. (The value refers to ground sensor 2.)
Select between -20 - + 50 ºC.
AFTERRUN 1
Indicates how long the unit continues to operate after ground
sensor 1 perceives the ground surface as dry.
Select from 0 minutes to 18 hours.
AFTERRUN 2
Indicates how long the unit continues to operate after ground
sensor 2 perceives the ground surface as dry.
Select from 0 minutes to 18 hours.
SET TEMP 1
Lowest start temperature for ground sensor 1.
Select between -20 up to the adjusted
SET TEMP 1 or OFF (OFF = no limit.)
SET TEMP 2
Lowest start temperature for ground sensor 2.
Select between -20 up to the adjusted
SET TEMP 2 or OFF (OFF = no limit.)
OFFSET T1
Used to calibrate ground sensor 1, see

heading. Select between -5 to + 5 ºC
OFFSET T2
Used to calibrate ground sensor 2, see
Calibration
heading. Select between -5 to + 5 ºC
OFFSET OUT
The function is not used for snow melting.
-
MIN WATER
Indicates the lowest return temperature for the system. On
delivery, the unit is provided with a resistor instead of a re-
turn temperature sensor. The resistor corresponds to a fixed
return temperature of 30 ºC.
Select between 0 and 40 ºC.
D 3 ºC
MAX WATER
States the highest supply temperature for the system.
NOTE!
MAX VALUE is 50 ºC for LK Snow melting.
Select between 0 and 60 ºC.
FACTORY RESET Reset the unit to factory setting.
Select EXIT or RESET
Sensor Heat Auto
When snow melting is activated, the heat-supply to the
sensor is switched off. In case of extreme circumstances,
heating of the sensor may occur continuously.
Select Auto or ON
MOIST CTRL
The ground sensor's moisture sensor can be switched off.
Then the power on/off of the snow melting is controlled only
on the basis of the set temperature.
NOTE!
When OFF is selected, the energy consumption
increases significantly.
Select ON or OFF
SENSITIVITY
The sensor's moisture sensitivity has five settings.
MN, LOW, NORM, HIGH and MAX
REINSTALL
