External demand
When the contact is closed, burner operation is load-
dependent. The boiler water is heated to the set value
selected in coding address "9b" in the
"General"/1
group. The boiler water temperature is limited by this
set value and by the electronic maximum limit (coding
address "06" in the
"Boiler"/2
group).
The external connection is switched via a floating con-
tact.
Connection options:
■
Plug
lH
■
EA1 extension (accessories)

■
The function is selected via code 4b:1 in the
"Gen-
eral"/1
group.
■
The effect on the circulation pump for cylinder heat-
ing is selected with code 5F in the
"DHW"/3
group.
■
The effect on the relevant heating circuit pump is
selected with code "d7" in the
"Heating circuit"
group.
EA1 extension
The "External demand" 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 codes:

■
The effect on the relevant heating circuit pump is
selected with code "d7" in the
"Heating circuit"
group.
■
The minimum set boiler water temperature for exter-
nal demand is selected in coding address "9b".
Screed drying
The screed drying function enables screeds to be
dried. For this, observe the screed manufacturer's
instructions.
When screed drying is activated, the heating circuit
pump of the mixer circuit is switched on and the flow
temperature is held in accordance with the selected
profile. After completion (30 days), the mixer circuit will
automatically be regulated via the set parameters
again.
Observe EN 1264. The report to be provided by the
heating contractor must contain the following details
regarding heat-up:
■
Heat-up data with the relevant flow temperatures
■
Max. flow temperature achieved
■
Operating state and outside temperature during
handover
The various temperature profiles are adjustable via
coding address "F1".
The function continues after a power failure or after the
control unit has been switched off. "Heating and DHW"
is started if screed drying is finished or if code "F1:0" is
set manually.
