External operating program changeover
The "External operating program changeover" function
is implemented via the EA1 extension. There are 3
inputs available at the EA1 extension (DE1 to DE3). The function is selected via the following coding
addresses in the
"General" group:
Heating program changeover Code
Input DE1 3A:1
Input DE2 3b:1
Input DE3 3C:1
Select the operating program changeover function for
the respective heating circuit at the boiler control unit,
via coding address "d8" in the
"Heating circuit"
group:
Heating program changeover Code
Changeover via input DE1 d8:1
Changeover via input DE2 d8:2
Changeover via input DE3 d8:3
You can select the direction of the operating program
changeover in coding address "d5" in the
"Heating
circuit" group:
Heating program changeover Code
Changeover towards "Continually reduced" or "Continuous standby mode" (subject
to the selected set value) d5:0
Changeover towards "Continuous heating mode" d5:1
The duration of the operating program changeover is
set in coding address "F2" in the
"Heating circuit"
group:
Heating program changeover Code
No operating program changeover F2:0
Duration of the operating program changeover 1 to 12 hours F2:1 to
F2:12
The operating program changeover stays enabled for
as long as the contact remains closed, but at least as
long as the duration selected in coding address "F2".
External blocking
The functions "External blocking" and "External block-
ing and fault message input" are implemented via the
EA1 extension. There are 3 inputs available at the EA1
extension (DE1 to DE3). The function is selected via the following coding
addresses in the
"General" group:
External blocking Code
Input DE1 3A:3
Input DE2 3b:3
Input DE3 3C:3
