The programmable periods for each zone are 7 and they can be
selected by changing the number that appears beside "Program
Confort period".
The "Comfort Setpoint" is the setpoint that is set for the area
served by the zone in the active time band established within
the period and can be set between ten and forty degrees.
Setting the "Comfort Setpoint" at a default of 20°C, the climat-
ic curve that regulates the setpoint of the zone is exactly that
which was set in paragraph Setting zone's climatic curve pa-
rameters (accessible only with installer password) on page 117
126.
By changing the "Comfort Setpoint" the climatic curve is moved
upwards or downwards depending on whether the setpoint is
higher or lower than 20°C. The curve will shift by two degrees for
each degree of difference between the value of the setpoint and
the value 20.
The "ECO Setpoint " is a setpoint that can be set between 5 and
20 degrees and can be selected as a setpoint for the area served
by the zone outside the active time band.
The "Out of the interval Setpoint" defines how the zone outside
the active time bands are managed (within which the setpoint
of the area is always set on "comfort").
The selections for the "Out of the interval Setpoint" are the fol-
lowing:
− Eco: the ambient setpoint is set to ECO. The zone setpoint
is changed by two degrees less for each degree of dif-
ference between the ECO setpoint and the value 20 (for
example, if at 20° I have a setpoint of 50, at 18 degrees I
have a setpoint of 50+2*(18-20)=46.
− Night-time: the zone setpoint is lowered by 10 degrees
with respect to the value of the zone setpoint set.
− Antifreeze: the ambient setpoint is set at 10°C, thereby
achieving a reduction compared to the zone setpoint of
20°C.
− Off: in this case the delivery of heat is interrupted.
− Comfort: the setpoint remains the same as that for the
active time bands. This choice clearly makes no sense
when scheduling is desired, but it can be useful if you
want to provide heat continuously without changing the
programming itself.

So that the zone programming works the "heat request"
contact should be closed. Otherwise the zone will ignore
any request from the schedule timer.

Using the option "Active Day(s)" it is possible to select the sched-
uling period. You can select a day of the week or else one of
these three groups of days:
− Mon-Sun
− Mon-Fri
− Sat-Sun
This facilitates weekly scheduling or else scheduling that is dif-
ferent during the work week and the week-end.
There are three active time bands for each period. The time res-
olution is 10 minutes.
