Note
To use a time program, select the required time pro-
gram from the standard menu (See section 7.3, "Standard
menu", pg. 7).
Note
Ensure the day of the week and the time are set correctly
when setting the time programs.
Note
The following applies to all time programs (Pro1, Pro2,
Pro3):
If the end time is later than 23:59 h, the end time will
automatically be moved to the next day of the week. The
comfort phase is maintained past midnight and will end
on the next day at the set end time.
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 heater heats
to the set comfort temperature. Outside this specified time period,
the heater operates in night mode. This results in a comfort phase
and a night phase, which are repeated daily (Pro1) or on every
working day (Pro2).
Theses phases are factory-set as follows:
- 08:00 am - 10:00 pm: Comfort mode
- 10:00 pm - 08:00 am: Night mode
Note
When time program Pro2 is enabled, the heater operates
during weekends exclusively in night mode.
To adapt time programs Pro1 and Pro2 according to your needs,
proceed as follows:
In the configuration menu, use "+" and "–" to call up the re-
quired time program.
Press "OK".
The start time for comfort mode is displayed.
Use "+" and "–" to set the required start time.
Press "OK".
The end time for comfort mode is displayed.
Use "+" and "–" to set the required end time.

P1: Room temperature offset
Uneven temperature distribution in the room can result in a differ-
ence between displayed actual temperature I1 and the room tem-
perature you measure. To compensate for this difference, a room
temperature offset of ±5 °F (±3 °C) can be set via parameter P1.
Example: The heater indicates I1 = 70 °F (21.0 °C). You have mea-
sured a room temperature of 68 °F (20.0 °C). There is a difference
of 2 °F (1.0 °C).
To compensate for the difference, select an offset of P1 = -2.0
(-1.0).
