FLOOR HEATING
7.1.
REGISTRATION
Activate Registration option in L-8 external controller and press the communication button in the selected floor temperature
sensor C-8f. If the registration has been completed successfully, L-8 display will show an appropriate message and C-8f control
light will flash twice to confirm.
7.2.
OPERATION MODE
Floor protection – this function serves to maintain the floor temperature below the maximum temperature value in
order to protect the system against overheating. When the floor temperature reaches the maximum temperature,
the zone heating is disabled.
Comfort profile – this function serves to maintain comfort floor temperature. The controller monitors the floor
temperature and disables the zone heating when zone temperature reaches the maximum temperature in order to
prevent overheating. When the floor temperature drops below the pre-set minimum temperature, the zone heating
will be enabled.
8.
HYSTERESIS
This function is used to define tolerance of the pre-set temperature in order to prevent undesired oscillation in case of small
temperature fluctuation. The setting range is 0,1 - 10⁰C with the accuracy of 0,1°C.
9.
CALIBRATION
Room sensor calibration should be performed while mounting or after it has been used for a long time, if the external
temperature displayed differs from the actual temperature. Calibration setting range is from -10
O
C to +10
O
C with the accuracy
of 0,1
O
C.

ACTUATORS
10.1.
REGISTRATION
This option concerns wireless actuators STT-868 or STT-869 - the registration process is described in detail in the user manual
for particular actuators.
Next to Registration icon, the display shows the number of registered valves (max.6).
10.2.
VALVE ACTUATORS
This option is used to remove the actuators STT-868 or STT-869 from the controller memory.
10.3.
SETTINGS
Sigma - SIGMA function enables smooth control of the thermostatic actuator. The user may define the maximum
and minimum valve opening – the level of valve opening and closing will never exceed these values.
Moreover, the user configures Range parameter, which defines the room temperature at which the valve starts
closing and opening.
NOTE
SIGMA function is available only with STT-868 and STT-869 actuators.
