The hot water may be set to a reduced temperature value, such as
61
40°C, which is outside the comfort zone, such as 60°C (daily pro-
gramme 8).
0 = 24 hours/ day - Hot water is always available at the temperature set
62
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.
This block (1) can be activated to display all the parameters without modif-
63
ying them. Pressing buttons
WARNING: The activation block can be deactivated temporarily by pressing
buttons
and
display. At this point press simultaneously the buttons
5 seconds.
To permanently remove the activation block, set parameter 63 on 0.
The freely programmable input (terminals 3 and 4 of the socket) allows three dif-
64
ferent 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.
If the entrance (terminals 3 and 4 of the base) is connected to a zero potential
65
external contact (parameter 64 = 2 or 3), the operating mode of the contact
can be determined (remote telephone switch or window contact). The operating
mode specifies the status of the contact in which the required function is active.
Display:
Operating mode closed (short circuit)
Operating mode open (interruption)
Determines the mix ratio between the internal and external ambient sensor

when parameter 64 = 1.
0 %
= internal sensor only active (0% external - 100% internal)
50 % = mean value of external + internal sensor
100 % = external sensor only active
The set mix is used for ambient control and display.
If the external sensor is short circuited or interrupted, the operation conti-
nues with the internal sensor.
