If the floor temperature exceeds the pre-set maximum temperature, the relay will be disconnected and the floor heating will
be disabled. The relay will be connected again when the floor temperature drops to the maximum temperature minus
hysteresis.
Example 2 – Comfort mode:
Minimum floor temperature:23°C Hysteresis: 2°C
When the floor temperature reaches 23°C, the relay is connected. It will be disconnected again at the temperature of 25°C.
If the floor temperature drops below the pre-set minimum temperature, the relay will be connected and the floor heating
will be enabled. The relay will be disconnected again when the floor temperature reaches the minimum temperature plus
hysteresis.
5.7. CALIBRATION
Floor sensor calibration should be performed while mounting or after the regulator has been used for a long time, if the
external temperature displayed differs from the actual temperature. Calibration setting range is from -10°C to +10°C with the
accuracy of 0,1°C.
6. HYSTERESIS
Room sensor hysteresis defines tolerance of the pre-set temperature in order to prevent undesired oscillation in case of small
temperature fluctuation (within the range 0,1 ÷ 10⁰C with the accuracy of 0,1 ˚C. ).
7. CALIBRATION
Room sensor calibration should be performed while mounting or after the regulator has been used for a long time, if the
external temperature displayed differs from the actual temperature. Calibration setting range is from -10°C to +10°C with the
accuracy of 0,1°C.
8. THERMOSTATIC ACTUATORS
8.1. 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.
8.2. VALVE ACTUATORS
This option is used to remove the actuators STT-868 or STT-869 from the controller memory.
8.3. INFORMATION
After this option has been selected, the display shows information about the actuator version, battery level, range and the
actuator opening level (%).
8.4. SETTINGS
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.
