Activating/Deactivating Phase Alignment; Activating/Deactivating The Single-Sensor Mode; Displaying The Heater Temperature In Single-Sensor Mode - Harvia SENTIO Professional B2 Instructions D'installation Et Mode D'emploi

Installation instructions, only for experts

8.2. Activating/deactivating phase alignment

Phase alignment is activated or deactivated using the function selection switch 3.
● The function selection switch 3 is set to the ON position as standard. Phase
alignment is therefore activated.
● If you wish to deactivate phase alignment, place the function selection switch 3
in the OFF position.

8.3. Activating/deactivating the single-sensor mode

In single-sensor mode, the sauna control unit is operated with the heater sensor
with an excess temperature fuse (F1) only. The single-sensor mode must be
activated above the function selection switch 5.
● The function selection switch 5 is set to the ON position as standard. Two-
sensor mode is therefore activated.
● If you wish to deactivate single-sensor mode, place the function selection
switch 5 in the OFF position.

8.4. Displaying the heater temperature in single-sensor mode

In single-sensor mode, the sauna control unit only displays the set temperature
as standard. The actual temperature is not displayed. Should the sauna control
unit display the temperature above the heater (F1) as an actual temperature in
single-sensor mode, it must be activated with the function selection switch 8.
● The function selection switch 8 is set to the ON position as standard. Therefore
only the set temperature is displayed.
● Should the temperature above the heater be displayed as an actual tempera-
ture, place the function selection switch 8 in the OFF position.
Ensure that the temperature above the heater is always higher than the
temperature in the area of the bench seat. With the heater temperature
as the actual temperature, the temperature displayed by the sauna con-
trol unit is higher than the temperature measured by your sauna room
thermometer.
