Time schedule profile programming.
A time schedule profile accepts Comfort and Economy
(Day and Night) modes only.
-
Programming of set point temperatures for heat and
cool in Occupied, Comfort or Day Modes.
-
Programming of set point temperatures for heat and
cool in Stand-by, Economy or Night Modes.
-
Programming of set point temperatures for heat and
cool in Unoccupied Mode.
Also used to define the number of days the thermostat will
remain off.
Plus and minus keys
These are
and
.
Pressing one of these two keys in Normal Mode accesses
the Setting Mode, displaying present temperature set point,
with the icon flashing (as long as the unit is not in OFF
mode).
If pressed and held for over 1 second, or released and pressed
again while still in the Setting Mode, said set point will be
increased or decreased in steps of 0.5° C or 1° F.
If in AUTO PROG MODE
icon will appear flashing, indi-
cating set point change is temporary. This change will remain
valid until a change is made in the occupation of the time
schedule profile. When this change in the time schedule pro-
file is made, the programmed set points are restored. Also, if
a change is made in the occupation status mode (Day/Night),
the programmed set point is re-established.
In the remaining air conditioning modes these changes are
made on the programmed set point values by means of the
programming menu.

AUTO
PROG
If the thermostat is in the AUTO or AUTO PROG mode, in the
Setting Mode one of the heat or cool icons only will appear. If
the Setting Mode is accessed with the
key, the heat
set point is displayed; if entered with the
key, the cool
set point. Once in the Setting Mode, the set point of the mode
not displayed (from cool to heat or vice versa) can be changed
by pressing the
MODE
key.
There is a total of six programmable temperature set points
that correspond to the heat and cool modes of the three occu-
pation modes (Day, Night and Unoccupied). These set points
must follow a descending order:
1. Cool set point in Unoccupied mode.
2. Cool set point in Night mode.
3. Cool set point in Day mode.
4. Heat set point in Day mode.
5. Heat set point in Night mode.
6. Heat set point in Unoccupied mode.
There should be a 1° difference between two consecutive set
points. If when moving one of the set points we come to less
than one degree centigrade from the following set point, it will
be "dragged" so as to avoid the unsuitability of the set points.
When this happens, the thermostat will flash the icon of the
occupation mode of this set point. Upon exiting the Setting
Mode these flashes and icons of the dragged set points dis-
appear.
If while in the Normal or Setting Mode both
and
keys are pressed simultaneously, the temperature reading goes
from °C to °F, and vice versa.
In the Programming Mode these keys allow changing the value
of the selected parameters.
Air conditioning mode key
It has the word
MODE
printed on the key itself, and the
symbol, related to the Programming Mode, printed on the plas-
tic over it.
Pressing this key in Normal Mode leads to the Setting Mode,
changing the present air conditioning mode (OFF, COOL,
HEAT, AUTO, AUTO PROG, EMERG HEAT). After pressing
this key the air conditioning mode will be displayed and flash
for 5 seconds, indicating the change, and then go back to the
Normal Mode.
In the Programming Mode , this key allows selecting the
previous option on the option list and move backwards through
the time schedule profile when programming same.
Occupation mode key
It has the symbol
printed on the key itself, and the
symbol, related to the Programming Mode, printed on the plas-
tic next to it.
Pressing this key in Normal Mode leads to the Setting Mode,
changing the present occupation or comfort mode (Day/Night)
and displaying the set point temperature next to the flashing
thermometer. If pressed once again while still in the Setting
Mode, each occupation mode will be accessed one by one in
a sequential and cyclic manner.
If while in the AUTO PROG (time schedule profile) mode the
occupation mode is changed and same does not coincide
with the mode programmed in the time schedule profile, the
icon of the selected mode will be displayed flashing, along
with the
icon, also flashing, indicating this is temporary.
