i) Switching between display of the desired
temperature and the actual temperature (“t-An”)
In the works, the desired temperature (i.e. the maximum
temperature the heating control permits the room temper-
ature to reach) is displayed on the right side of the large
display of the “FHT8R” heating control. You can use the
special function “t-An” to activate a mode displaying the
actual temperature (i.e. the currently measured room tem-
perature).
In this mode the desired temperature is only displayed if
you turn the selection wheel. To indicate that the displayed
temperature is the desired temperature the temperature unit
(°Cor°F)ashes.
If the set value is not changed for several seconds, the
heating control automatically returns to the display of the
actual temperature.
