Correction selector for comfort mode.
Range of adjustment from -25% to +25%.
Factory setting: correction = 0%.
The selector determines a parallel displacement of the
characteristic curve according to the new percentage value
selected in the comfort range (red indicator).
Example: if the selector is set to +25%, its effect on the flow
temperature will be as follows:
+25% ∆Y = 0,25 · 25 = 6,25°C.
The characteristic curve is then moved upwards by 6,25°C.
This has no effect on the cooling function.

Correction selector for set-back mode.
Range of adjustment from 0% to -50%.
Factory setting: correction = -25%.
The selector determines a parallel displacement of the
characteristic curve according to the new percentage value
selected in the set-back range (blue indicator).
Example: if the selector is set to -25%, its effect on the flow
temperature will be as follows:
-25% ∆Y = -0,25 · 25 = -6,25°C.
The characteristic curve is thus moved downwards by 6,25°C.
In addition, if, following this move, the flow temperature has to
be lower than the minimum heating start temperature (Tmin Y),
the following state will be obtained:
circulator OFF and mixing valve closed.
This has no effect on the cooling function.

13)Daily or weekly analogue clock, used to select the heating and
cooling phases required with:
the red indicators for heating comfort and set-back and the blue
indicators to start and stop cooling.
Factory configuration: daily mode, minimum selection interval 15 min..
The changeover from daily to weekly mode, with a 60 min. minimum
selection interval, is carried out as follows:
raise the outer ring and move the
drive ring to the required position;
to do this, turn the pointer clockwise
until the innermost notch coincides
with one of the outer notches.
Reposition the outer ring, making
sure that the reference day shown
on it falls in the operating sector
of the switching point.

Minimum outside temperature (Tmin X), adjustable from -5°C
to -20°C, to which the set maximum flow temperature
corresponds (Tmax Y). Factory setting: -10°C.
2)
Set-back mode exclusion selector, adjustable from
0°C to -20°C. Factory setting: -15°C.
If the outside temperature falls below the set value, the heating
is reactivated according to the characteristic curve of the
comfort mode.
3)
Maximum outside temperature to start heating, or summer
limit, (Tmax X), adjustable from 14°C to 22°C.
Factory setting: 18°C.
An outside temperature higher than the set value will cause the
following state: circulator OFF and mixing valve closed. An outside
temperature 4°C higher than the set value will cause activation of
the cooling, if this outside temperature is greater than the value set
on the front panel, item 10. - e.g.: T
on PCB=22°C.
Activation will take place at T
4)
Selection microswitch for screed setting drying program.
Factory setting: OFF (1234).
This program is used for carrying out correct drying of the
screed, above which the final flooring will be laid (its activation
excludes all other functions).
The program has a duration of seven days: during the first three
days, the flow temperature is maintained at 25°C, whilst for the
remaining four days, the flow temperature is raised and maintained
at the maximum temperature value set at point 9 on the front panel.
The activation of this program is displyed by the flashing LED
on the front panel, point 1.
The frequency of flashing indicates the number of drying days
which have passed: one pulse every 8 seconds indicates
day 1, two pulses every 8 seconds indicates day 2, etc. If the
electricity has to be switched off in this phase, the controller will
start its drying cycle again from the beginning. The front panel
LED, point 1, continuously lit, indicates the end of the drying
program. At this point the microswitch should be turned to OFF.
Note: In manual mode
activated.
When cooling, this series of microswitches has the function of
limiting the minimum temperature transmitted to the panel. This
minimum temperature depends on the characteristics of the
system and the type of air conditioning adopted. The different
activation configurations are shown below.
Factory configuration: 16°C.
