TEMPERATURE CHART
The Roma programmable chronothermostat has a temperature chart that
shows a diagram made up of 24 columns that represent the HOURS of the
day.
Two temperatures can be programmed for each HOUR:
-the temperature of the FIRST HALF HOUR (e.g. from 00:00 to 00:29)
-the temperature of the SECOND HALF HOUR (e.g. from 00:30 to 00:59)
The heights of the columns change only when setting the temperatures for
the FIRST HALF HOURS of each hour.
BASICS
• In the WEEKLY PROGRAMMING screen, the target temperature flashes.
• To exit the WEEKLY PROGRAMMING, touch the ON/OFF button.
• Functions can be turned on by touching the display, pressing the touch areas.
GENERAL DESCRIPTION
Roma is a touch-screen, wall-mounted programmable chronothermostat that
lets you easily set the temperature of your home. Roma has a backlit display to
graphically display the target temperatures, which can be changed using sim-
ple and practical commands that make programming it very easy.
Roma can control heating and cooling systems. It avoids energy waste by run-
ning the heating or air conditioning system only when needed.

POWER ON/RESET
After inserting the batteries and selecting the RESET function, the program-
mable chronothermostat performs a checkup by turning on all parts of the
display and activating the load for a few seconds (Fig. 8). After a few sec-
onds the programmable chronothermostat goes into STAND-BY ON mode
(Fig. 9). Roma is pre-programmed with a weekly temperature program,
which can be modified at will.
Fig.8 Fig.9 Fig.10
The programmable chronothermostat’s RESET function can be accessed
from the Home Screen (Fig. 10) by pressing the measured temperature
area and the TIME area together.
-Each COLUMN is made up of three temperature CURSORS (Fig. 8):
Fig. 8
In WINTER mode “ ” :
The 3rd CURSOR includes temperatures from 20.0°C to 30.0° C.
The 2nd CURSOR includes temperatures from 16.1°C to 19.9°C.
The 1st CURSOR includes temperatures from 5.0°C to 16.0°C.
In SUMMER MODE “ ” :
The 3rd CURSOR includes temperatures from 29.0 °C to 35.0 °C.
The 2nd CURSOR includes temperatures from 27.0 °C to 28.9 °C.
The 1st CURSOR includes temperatures from 15.0 °C to 26.9 °C.
Let’s assume you want to set the temperature of the “0”hour:
By setting the temperature to 18°C for the FIRST HALF HOUR, the col-
umn of HOUR “0” will change its height with respect to the pre-set program
(Fig. 12). If you set the temperature to 25°C in the SECOND HALF HOUR,
the “0” HOURS column will not change (Fig. 13).
Fig.12 Fig.13
Therefore: Setting the temperature of the SECOND HALF HOUR of each
HOUR does not make the corresponding HOUR column change, even you
set it to a different temperature with respect to the temperature of the FIRST
HALF HOUR of that HOUR. The display will show the trend of the target
temperatures throughout the day. The temperature CURSOR of the cur-
rently selected HOUR flashes.

MAINTENANCE RANGE
The MAINTENANCE RANGE is the range beyond which the program-
mable chronothermostat calls for heating/cooling. The range is centred on
the TARGET TEMPERATURE.
You can make it smaller or greater, depending on how the room’s tempera-
ture changes (size of the room and influences from outside).
In WINTER mode ( ) the programmable chronothermostat turns on the
heating system when the temperature measured in the room is:
SET TEMPERATURE - 1/2 OF MAINTENANCE RANGE
The heating system is turned off when the measured temperature is:
SET TEMPERATURE + 1/2 OF MAINTENANCE RANGE
Conversely, in SUMMER mode ( ) the cooling and/or air conditioning
system
is turned on when the measured temperature is:
SET TEMPERATURE + 1/2 OF MAINTENANCE RANGE
The cooling and/or air conditioning system is therefore turned off when the
measured temperature is:
SET TEMPERATURE - 1/2 OF MAINTENANCE RANGE
The MAINTENANCE RANGE is pre-set in the programmable chrono-
thermostat to 0.4°C or the WINTER mode ( ) and to 0.8°C for the
SUMMER mode ( ).
Therefore, for example:
Program: WINTER ( )
- SET TEMPERATURE: 20.0 °C
- MAINTENANCE RANGE: 0.4°C
TEMPERATURE MEASURED:
20.0 – 0.2 °C = 19.8 °C HEATING SYSTEM ON
MEASURED TEMPERATURE:
20.0 + 0.2 °C = 20.2 °C HEATING SYSTEM OFF
You can access the Home Screen from STAND-BY ON mode by simply
touching the display.
To change the MAINTENANCE RANGE (dt) from the Home Screen,
press the TEMPERATURE area on the display for 2 seconds (Fig. 49).
"dt" will be shown in the lower area of the display and the maintenance
range value currently set for the relative program will be shown in the up-
per area. You can then adjust the dt between 0.2°C and 2°C using the +C
or
-C
buttons (Fig. 50).
