2. 1 0.3 Gradient of the characteristic
heating curve
The gradient of the characteristic heating
curve is imposed on the current value "15"
of Logica. Increasing the gradient as shown
in the drawing of fig. 18, the delivery tempe-
rature increases in correspondence to the
outside temperature.
2. 1 1 EXTERNAL TEMPERATURE
SENSOR
The "Logica Remote Control" can be connec-
ted to an external temperature sensor availa-
ble a an optional extra (code 8094100). This
configuration ensures and maintains the
required temperature constant in the room.
The ambient temperature is, in fact, indicted
and evaluated as the calculated mean of the
value measured inside and outside the dwel-
ling. For installation, follow the assembly
instructions inserted in the package.
The freely programmable input (terminals 3-4) allows three different functions
64
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.
Se a entrada (bornes 3 e 4 do ropadé) está ligada a um contacto externo de
65
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)
modo de acção aberto (interrupção)
Determina o coeficiente de mistura entre a sonda ambiente interna e exter-
66
na, quando o parâmetro 64 = 1.
0 % = activa só a sonda interna (0% externa - 100% interna)
50 % = valor médio da sonda externa + 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
69
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
Example: Choosing a gra-
dient of 15 with an outsi-
de temperature of –10°C
we shall have a delivery
temperature of 60°C.
