THE PROGRAMMABLE THERMOSTAT
Roma Wi-Fi
semi-recessed Wi-Fi touch-screen programmable thermostat
BY

Roma Wi-Fi is a semi-recessed Wi-Fi touch-screen programmable thermostat with an APP to
control the temperature of your home simply and easily, using your smartphone or tablet.
Roma Wi-Fi
has a backlit display to graphically display temperatures, which can be changed using
simple and practical commands that make setting it up it very easy.
Roma Wi-Fi can control heating and cooling systems.
It avoids energy waste by running the heating or air conditioning system only when needed.
N.B. TURN OFF ELECTRICAL POWER BEFORE CONNECTING THE
Roma Wi-Fi PROGRAM-
MABLE THERMOSTAT.
Warning: Electrical connections must be made using subsurface ducted wiring.
N.B. Connect the electrical load before connecting the mains (Fig. 1).
The electrical connection terminals are located behind the Wallplate.
The
Roma Wi-Fi programmable thermostat must be powered by 230Vac - 50/60 Hz on terminals 1
and 2 (Fig. 1).

Roma Wi-Fi can be installed both in recessed 2-module junction boxes (502 type) and in recessed
3-module junction boxes (503 type). In both cases, the recommended height is 1,5m above the
floor, in a dry, draught-free place, away from heat sources. After making the electrical connections,
fasten the Wallplate to the recessed junction box using the included screws, making sure that the
Wallplate’s Locking Clip is on the bottom side (Fig. 2).

FIRST POWER-UP
When you power up your
Roma Wi-Fi programmable thermostat, it performs a check-up by turning
on all the parts of its display and turning on the load for a few seconds (Fig. 5).
Then the Roma Wi-Fi programmable thermostat shows the Home Screen (Fig. 6).
After about ten seconds it shows the STAND-BY screen (Fig. 7).
When powered up for the first time, Wi-Fi is off. N.B. After configuring the Wi-Fi module, every
time mains power resumes, the programmable thermostat will send your mobile device a push-
notification reporting: "Mains power present.”
Fig.5 Fig.6 Fig.7
Roma Wi-Fi is pre-programmed with a weekly temperature program, which can be modified at
will (Fig. 6).

TEMPERATURE CHART ON THE PROGRAMMABLE
THERMOSTAT’S DISPLAY
The
Roma Wi-Fi programmable thermostat can display a temperature chart that shows 24 col-
umns, to represent the 24 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.
-Each COLUMN is made up of three temperature CURSORS (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 column of HOUR 0 will change
its height with respect to the pre-set program (Fig. 9).
If you set the temperature to 25°C in the SECOND HALF HOUR, the 0 HOURS column will not
change (Fig. 10).
(Fig. 8).

11
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 currently selected
HOUR flashes.
SYSTEM CONTROL CONTACT
The heating/cooling system is turned on or off when the target
temperature is reached by switching the relay contact.
The “ ” symbol shows that the heating/cooling system is on (Fig. 11).

CORT
(Measured Temperature Correction)
Use the "Cort" Temperature Correction function if the room temperature is incorrectly measured
due to disturbing elements such as heaters, coolers, etc.
On Roma Wi-Fi, you can compensate the temperature measured by the programmable thermo-
stat in a range from -5°C to +5°C.
Example:
Let’s suppose you set the "Cort” “Temperature Correction” to: -2.0°C.
If Roma Wi-Fi displays a temperature of 20.0 °C while the real temperature is 22,5°C,
you can use the "Temperature Correction” function to set +2.5°C so that: 20°C+2,5°C =22,5°C
Access the Setup Menu from the Home Screen by pressing the measured TEMPERATURE area
and the TIME area together, for 2 seconds.
-Press the “
