programming block
Input function terminal 3-4
This block (1) can be activated to display all the parameters without
modifying them. Pressing buttons
or
displays
“OFF”
.
WARNING:
The activation block can be deactivated temporarily by pressing buttons
and
simultaneously; a confirmation sign appears on the display.
At this point press simultaneously the buttons
and
for at least 5
seconds.
To permanently remove the activation block, set parameter 63 on 0.
The freely programmable input (terminals 3-4) allows three different functions
to be activated. The parameter has the following significance:
1
= If an external sensor is connected, the display will show the temperature
of the external sensor ( _ _ = no sensor connected, function disabled).
2
= With an external contact, it is possible to switch-over to "reduced pre-
set value of the ambient temperature".
3
= With an external contact, it is possible to switch-over to "reduced pre-
set value of the antifreeze ambient temperature" (short circuit 0 0 0 or
interruption _ _ _ ). The display shows the current status of the external
contact.

SERVICE VALUES
DOMESTIC HOT WATER SETTINGS
Reduced domestic hot
water pre-set value
Domestic hot water load
The reduced pre-set value of the temperature of the domestic hot water allow
the required water temperature to be obtained outside the programmed
usage times (daily programme 8).
0
= 24 hours/ day - Hot water is always available at the temperature set
with user parameter n°3.
1
= standard - Hot water according to the daily heating programme.
In the comfort areas of heating the temperature of the boiler unit is regu-
lated to the value set with user parameter n° 3.
In the reduced areas of heating the temperature of the boiler unit is
regulated to the value set with parameter n° 61 of the service level.
2
= service disconnected
3
= second daily programme (8) - Every day of the week the temperature of
the hot water is set according to programme 8. In this case there is a
single programming for all the days of the week and three time zones are
available. In the time spans set the temperature of the boiler unit is regu-
lated according to that set in parameter n°3. In the remaining hours the
boiler unit is controlled to the temperature set with parameter n° 61 the
of service level.

Modo de acção do contacto externo

am externa
Anti-bacterial function
Se a entrada (bornes 3 e 4 do ropadé) está ligada a um contacto externo de
potencial zero (parâmetro 64 = 2 ou 3), pode ser determinado o modo de
acção do contacto (tele-interruptor do telefone ou contacto janela). O modo de
acção especifica o estado de contacto no qual a função desejada está activa.
Display:
modo de acção fechado (curto-circuito)
0 0 0
modo de acção aberto (interrupção)
_ _ _
Determina o coeficiente de mistura entre a sonda ambiente interna e exter-
na, quando o parâmetro 64 = 1.
0 %
= activa só a sonda interna (0% externa - 100% interna)
50 %
= valor médio da sonda e interna
100 %
= activa só a sonda externa
Para a regulação ambiente e a visualização, é utilizada a mistura programa-
da. Se a sonda externa apresenta um curto-circuito ou uma interrupção
prossegue-se com a sonda interna.
This function allows the hot water to be brought to a high temperature once
a week in order to eliminate eventual pathogenic agents.
It is active every Monday for a maximum duration of 2.5 hours at a delivery
temperature of 65°C.
0 = not active 1 = active
