Time programs Pro1 and Pro2
You can specify the comfort mode start and end times with time
programs Pro1 and Pro2. During this time period, the appliance
heats to the set comfort temperature. Outside this specified time
period, the appliance operates in setback mode. This results
in a comfort phase and a setback phase, which are repeated
daily (Pro1) or on every working day (Pro2).
Theses phases are factory-set as follows:
- 08:00 h - 22:00 h: Comfort mode
- 22:00 h - 08:00 h: Setback mode
Note

ates at weekends exclusively in setback mode.

display description
P1 Room temperature offset
P2 Time format
P3 Temperature display units
P4 Reset time programs (timer mode).
P5 Reset relative heating time

relevant parameter. Press "OK".
As soon as the "Editable parameter" symbol appears, you can

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. f
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 to the factory
setting.
