9. DESIGNING A PROGRAM
Execution of a daily of weekly program means that the thermostat
will be ON and the temperature will follow the pre-designed plan. Up-
to 10 different temperature variations can be programmed in a 24
hour day cycle.
In the top right corner you can see the desired temperature whereas
in the top left corner you can see the time for this temperature. This
largest portion of the screen shows the design field.
The horizontal axis shows the time scale from 0 to 24, whereas the
vertical axis shows the temperature from 5 to 30
o
C.
The design is done using a cursor as shown in the diagram.
The cursor shows that at the time 16:15 the desired temperature is
21,0
o
C. With the keys
and
you can move the cursor
horizontally
,
while simultaneously you can view the time and the
temperature for that specific point where the cursor is.
On the right side of the screen you can see the indication
“Μ3” which
shows how many temperature variations are in the program. If
we
design a new program we must first erase the old program.
With the key
move the cursor to the time 00:00. Press the
ENTER
,
key for the desired temperature to become 0,0
o
C. Press the
ESC
key and the cursor will change
shape and become “=”. Now with the
key
move the value 0,0
o
C up-to the time 23:45. Press the
ESC
key in order for the cursor to change to its original shape and then
using the key
move the cursor to the time 00:00.
Now the design field is empty and the cursor is in the time 00:00,
where the desired temperature is 0,0
o
C.
We will design a program where for the time 00:00 to 06:30 the
desired temperature will be 18
o
C, and from 06:30 to 08:00 will be 21
o
C, from 08:00
έως τις 16:30 will be 18
o
C, from 16:30 to 23:00 will be
21
o
C and finally from 23:00 to 24:00 will be 18
o
C.
With the keys
(and
) adjust the temperature setting until is
becomes 18
o
C.
Press the
ESC
,
the cursor will become “
=
”. With the keys
and
move the cursor and carry the same temperature up-to the time
06:15.
Observe that in order to set 18
o
C, from 00:00 to 06:30, in reality
we moved the cursor up-to 06:15. This is done because the
design field is divided into 96 sections (96 quarters of an hour).
The first section starts from 00:00 and ends at 00:15, the second
section starts at 00:15 and ends at 00:30 and so on. In this way,
in order to select the second section we move the cursor to
00:15 and not 00:30.
Next, using the keys
and
adjust the temperature setting until is
shows 21
o
C and with the
key move this value until the time 07:45.
Next, using the keys
and
adjust the temperature setting until is
shows 18
o
C and with the
key move this value until the time 16:15.
