*1 : Only available if APp a AF is selected under Application.
*2 : Only available if APp a Li is selected under Application.
*3 : Only available with external timer.
*4 : With no or disconnected sensor, - - is shown on the display.
*5 : Only available if PWM is ON under Control Method.
*6 : Only available if PWM is OFF under Control Method.
If Regulator (C) is selected under Application, the floor and room sensors are discon-
nected and heating is controlled on a scale of 0-10, corresponding to 0-100 % of full
power.
Settings
To set parameter values, press and hold the centremost button for
three seconds. SCA a Hi a 40 will appear on the display. Firstly,
SCA will be displayed for 1 second, followed by Hi, and finally 40.
The required value can now be set using the navigation buttons. To
access the next parameter, press the programming button again.
If no button is pressed for 30 seconds, the program returns to the
initial display.
Max. temperature
The highest temperature to which the thermostat can be set.
Min. temperature
The lowest temperature to which the thermostat can be set.

Max. limit temperature
Allows the highest permissible floor temperature to be set for
wooden and other floor types when control type has been set to
room sensor with floor limit (AF).
Min. limit temperature
Allows the lowest permissible floor temperature to be set for tiled
and other floor types when control type has been set to room sen-
sor with floor limit (AF).
Limit function
If application (APp) is set to limit (Li), the lowest temperature at
which heating is to be provided can be set.
Frost protection
The lowest temperature for frost protection when the function is
activated via an external signal (See instruction).
Example: The setpoint is 25 °C.
Frost protection = 8 °C means temp. setting = 8 °C.
Night setback / energy-saving function
The number of degrees the temperature setting is to be reduced.
The night setback setting must be preceded by a minus sign (-). Is
controlled via an external signal (See instruction).
Example: The setpoint is 25 °C.
Energy-saving function = -5 °C means temp. setting = 20 °C.
Energy-saving function = +3 °C means temp. setting = 28 °C.
Measured floor temperature
Displays actual floor temperature (if a floor sensor is fitted).
Measured room temperature
Displays actual room temperature.
Application
Sets thermostat function. Select the required control type.

Limit is an on/off function in which the
required limit is set in Limit low ("Li" a "Lo")
after selecting the Li option under APp. When
the recorded temperature is above the tem-
perature specified in "Li" a "Lo", temperature
is controlled in the usual way towards the
user-specified setpoint. If, on the other hand,
the temperature drops below that specified in
"Li" a "Lo", the relay cuts out and "Lo" ap-
pears on the display.
Limit function (APp a Li) should be selected if
a limit is required for when heating is permit-
ted to be activated. Only one sensor is used
for the limit function, and this sensor must
be connected to the floor sensor input of the
thermostat.
The thermostat controls room temperature
while respecting min. and max. limits for floor
temperature. A floor sensor must be fitted.
