Digital inputs DE1 to DE3
Functions:
■ External operating program change-
over for heating circuits 1 to 3 sepa-
rately
■ External blocking
■ External blocking with fault message
input
■ External demand with minimum flow
temperature
■ Fault message input
■ Brief operation of the DHW circulation
pump
When connecting external contacts,
observe the requirements of safety cat-
egory II, i.e. 8.0 mm air-gap and creep
paths or maintain a 2.0 mm insulation
thickness against 'live' parts.
Input function assignment
Select the input functions by means of
the following codes in the "General"
group at the boiler control unit:
■ DE1: Coding address "5d"
■ DE2: Coding address "5E"
■ DE3: Coding address "5F"
Assigning the operating program
changeover function to the heating
circuits
The assignment of the operating pro-
gram changeover to the relevant heat-
ing circuit is set at coding address
"d8" in the "Heating circuit..." group:
■ Code "d8:1": Changeover via input
DE1
■ Code "d8:2": Changeover via input
DE2
■ Code "d8:3": Changeover via input
DE3
Select the effect of the operating pro-
gram changeover at coding address
"d5" in the "Heating circuit..." group:
Duration of the operating program
changeover
■ Contact constantly closed:
The changeover is enabled as long as
the contact is closed.
■ Contact only closed briefly via push-
button:
The changeover is enabled for the
time selected in coding address "F2" in
the "Heating circuit..." group.
DHW circulation pump runtime for
brief operation
The DHW circulation pump can be star-
ted outside the times when it is enabled
according to the time program.
The DHW circulation pump is started by
closing the contact at DE1, DE2 or DE3
by means of a pushbutton. Set the run-
time at coding address "12" in the "Gen-
eral" group.
