External Extension - Viessmann VITOTRONIC 200 Service Instructions Manual

Parameter group System definition
700F Output control strategy, cascade
To control the output of the heat pump cascade the
flow temperature in the secondary circuit is captured.

7010 External extension

Areas of application for EA1 extension:
Swimming pool heating
■
External changeover of the operating status
■
■ External demand/external mixer OPEN or control
function
■ External blocking/external mixer CLOSE or control
function
Defaulting the set flow temperature in the case of
■
external demand by analogue voltage signal 0 to
10 V
■ Minimum heating water temperature (secondary cir-
cuit flow temperature)
■ Smart Grid
Note
For swimming pool heating, the following functions
cannot be achieved:
■ External changeover of the operating status
■ External demand to the heat pump/external mixer
OPEN
Note
With Smart Grid, the following functions cannot be
achieved:
■ External changeover of the operating status
■ External demand
■ External blocking
7011 System components for external changeover
Selection of system components for which the operat-
ing status should be changed for a certain period of
time. With a ventilation unit, the ventilation level is
changed.
■ Heating circuits, DHW heating, buffer cylinder:
The operating status to be selected is specified by
parameter "Operating status for external change-
over 7012".
■ Ventilation:
The ventilation level to be set is specified with
parameter "Effect of OM changeover to ventila-
tion 701F".
The duration of the changeover is specified by
■
parameter "Duration of external changeover
7013".

Setting in the bit field (see chapter "Setting parame-
ters"): Several bits can be selected.
Note
opens the setting assistant.
Bit Meaning
"Bit 1" EA1 extension
"Bit 2" AM1 extension
"Bit 3" Do not adjust.
The setting results from the combination of selected
bits.
!
Note
The function "Effect of external demand on heat
pump/heating circuits 7014" has a higher priority
than the function "System components for external
changeover 7011".
Setting in the bit field (see chapter "Setting parame-
ters"): Several bits can be selected.
Note
opens the setting assistant.
Bit Meaning
"Bit 1" Heating circuit without mixer A1/HC1
"Bit 2" Heating circuit with mixer M2/HC2
"Bit 3" Heating circuit with mixer M3/HC3
