display description
P1 Room temperature offset
P2 Time format
P3 Temperature display units
P4 Reset the time programs (Pro1, Pro2, Pro3).
P5 Reset relative heating time
To change the value of a parameter, use "+" and "–" to call up the
relevant parameter. Press "OK".
As soon as the "Editable parameter" symbol appears, you can
change the parameter value with "+" and "–". Press "OK" to save
the selected value.
P1: Room temperature offset
Uneven temperature distribution in the room can result in a dif-
ference between displayed actual temperature I1 and the room
temperature you measure. To compensate for this difference, a
room temperature offset of ±3 °C can be set via parameter P1.
Example: The appliance indicates I1 = 21.0 °C. You have measured
a room temperature of 20.0 °C. There is a difference of 1.0 °C.
f To compensate for the difference, select an offset of P1 = -1.0.
P2: Time format
Parameter P2 allows you to specify whether the time is displayed
in the 12 hour or 24 hour format.
P3: Temperature display units
Parameter P3 is used to specify whether the room temperature is
displayed in degrees Centigrade [°C] or Fahrenheit [°F].
P4: Reset time programs
Activating parameter P4 resets all time programs (Pro1, Pro2,
Pro3) to the factory setting.
P5: Reset relative heating time
Activating parameter P5 resets the counter for relative heating
time (I2).
6. Cleaning, care and maintenance
