Due to the tolerances of sensors, deviations of
+/- 2K (2°C) are normal between various
temperature displays. Temperatures which change
rapidly can have higher deviations for short periods
due to the different time-related behaviour of various
sensors.
!
The display of the current heating program applies
to the device's first heating circuit.
In case of having two heating circuits the display can
be set to the 2nd circuit
Explanations
A Current
time
B
Freely selectable display
(refer to "DISPLAY SEL" parameter)
C
DCF reception OK
(only if receiver is connected via eBUS)
D
Bus icon (if this icon does not appear, check data
line to connected CAN controllers
=> check eBUS via DISPLAY level)
E
Display of the active heating program for the first
heating circuit
(here: 6:00 to 08:00 hrs and 16:00 to 22:00 hrs)
F Status
display:
H
internal burner 1 relay ON;
D
heating mode;
F
hot water preparation
G
Mode selector switch, the display applies to all
internal heating circuits for which a separate
operating mode has been selected via the "MODE"
set value (here:
F
2
=> Heating according to timer
program 2).
H
Display of current temperature of HS 1 or header
temperature in the case cascades
I
Display of numbers of active heat generators
(only applies to cascades)
