In the first step is set the starting time by pushing
the + and ‐ buttons at intervals of at least 15
minutes and you confirmby pushing OK. If you
want to quit the programming of the selected day,
push ESC.
In the second
step, pushing
the
◄
and
►
you select
which of the
four
programmed
temperatures will be associated to the time slot.
Push OK to confirm or ESC to return
In the third step
you select the
ending time.
The final time
cannot be less
than the initial
time.
The last item on
the
“Programming”
menu allows you
to copy the
program day to
another day.
At the top you select the source day in the lower
you select the destination day, You can also copy a
program of the day all week and have the same
program every day, to do this select as target the
"ALL". When you press OK, a message confirms
your copy of the program.
Time
setting
Allows the
adjustment of
the current time
and day of the
week.
Pushing the ↓
and ↑ buttons you select the item you want to
change, while pushing the + and ‐ buttons you
change the value. Pushing the OK button confirms
the changes.
Language
setting
Allows to
select the
language on
the chrono‐
thermostat.
As seen above
this setting is required when you first start or after
a reset of the chronothermostat.
Heating
control
This submenu
concerns the
method used by
the chrono‐
thermostat for controlling room temperature.
This menu allows you to set the differential, which
can vary between 0.2 º C and 5.0 º C (default value:
2.0 º C). d is the thermal differential, Max is the
maximum rate, Ti and Ta stand for respectively
room temperature set and room temperature
measured.
The required percentage P is calculated as follows:
if Ta ≤ Ti ‐ d then P = Max
if Ti – d < Ta < Ti then P = ( Max / d ) x ( Ti – Ta )
if Ta ≥ Ti then P = 0
Example
1
:
Ti = 20,0ºC
Max = 100%
d = 0,5ºC
If Ta ≤ 19,5ºC then P = 100%;
If 19,5ºC < Ta < 20,0ºC then P = (100 / 0,5) x (20 – Ta) %
if Ta ≥ 20ºC then P = 0
.
On the same page you can enter the hysteresis
value (asymmetric) in order to avoid frequent
restart heaters. Hysteresis may vary in steps of 0.1
º C between 0.1 º C and 50% of the set differential
value.
After reaching the set temperature Ti, the
chronothermostat controls the switching off of the
heaters, the following restart will take place only if
the temperature falls under the set temperature
decreased hysteresis (Ti‐hysteresis). The default
hysteresis is 0.1 º C
Example
2:
Ti
=
20,0ºC
Max
=
100%
d
=
0,9ºC
hysteresis
=
0,4ºC
(hysteresis
can
vary
between
0,1ºC
e
diff/
2
=
0,4ºC)
When
Ta
≥
20ºC
then
P
=
0,
and
the
heaters
are
turned
off.
A
restart
occurs
if
Ta
≤
(Ti
–
hysteresis)
=
19,6ºC;
in
particular
if
19,1ºC
<
Ta
≤
19,6ºC
then
P
=
(
100
/
0,9
)
x
(
20
–
Ta
)
%,
while
if
Ta
≤
19,1ºC
then
P
=
100%.
From software version 1RZ005 on, it is possible to
set an OFFSET temperature between ‐5.0°C and
+5.0°C (defaut = 0.0°C)
