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.
Note:
* Room sensor not in use.
Floor (F):
The thermostat controls floor temperature
alone.
A floor sensor must be fitted.
Room (A):
The thermostat controls room temperature
alone.
Limit (Li):
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.
Room/limit (AF):
The thermostat controls room temperature
while respecting min. and max. limits for floor
temperature. A floor sensor must be fitted.
