WARNING !
When the display shows the symbol blinking, the supply batteries are running down.
CHANGE THEM IMMEDIATELY.
If the battery charge drops under the minimum level, the timer-thermostat output relay automati-
cally switches OFF and it is no longer possible to perform any control operations by using the
device.
Flat batteries and their renewal do not delete the programs or the settings; after changing, it will
in fact be necessary to reset only the date and time.
In addition, if the timer-thermostat is not used for a long period of time, it is always recommended
to remove the batteries so as to prevent any acid leaking out that would damage the device.
For the battery life to be assured, it is always necessary for the front of the timer-thermostat to be
closed after opening to access the vertical temperature sliders.

1. THE TIMER-THERMOSTAT 01911
The Vimar 01911 timer-thermostat is able to assure ideal tempera-
ture conditions for every hour of the day.
It is equipped with a large display for viewing the temperature and
the settings, a push-button and knob for selecting and programming
the functions and a set of vertical sliders that are used to adjust the
temperature extremely simply.
The timer-thermostat can work in different modes, also timed, and
with two types of automatic operation (during which it is also pos-
sible to change the programmed temperature temporarily).
The device is powered with two AA LR06 1.5 V penlight batteries
that are easily found on the market and assure a power supply for
the device for over a year.

means that the timer-thermostat is keeping the air-conditioning
on.
If the display does not show either of these two symbols, it
means that the heating or air-conditioning is off at that time.

control (heating and air conditioning), changeover relay output 5(2)
A 250 V~, power supply with penlight batteries AA LR6 1.5 V (not
supplied), surface mounting, white.
4. FIELD OF APPLICATION
The appliance is designed to control room temperature by acting on
the control circuit of the burner or circulation pump (heating) or on
the control circuit of the air conditioner (air conditioning), ensuring an
ideal temperature, every day, throughout the week.
The large display shows the room temperature, day, time, system
operating status and the daily profile set for the current program.
5. INSTALLATION
The appliance must be installed on a wall at a height of 1.5 m off the
floor in a suitable position for correctly detecting the ambient tem-
perature. It must not be installed in niches, behind doors and curtains
or in areas affected by sources of heat or atmospheric factors. In
particular, it must not be installed on outer walls.
The base of the appliance has 4 slots for installation straight onto
a wall with screws and plugs ø 6 mm (not supplied) or for installa-
tion in recess-mounting enclosures with anchoring by screws with
centre distance 60 mm or 83.5 mm (3-gang joined rectangular
enclosures).
It should be used in dry, dust-free places at a temperature between
0 °C and +40 °C.

6.1 Phone dialler control
It is possible to control the timer-thermostat remotely with a phone
dialler connected to the dedicated terminals (see the figure below).
• By closing the contact, the timer-thermostat is forced onto Manual
operation and the keys are locked.
• On opening the contact the timer-thermostat is forced onto:
- Antifreeze mode if heating is on;
- OFF if air-conditioning is on.
Note: If the user has remotely forced timer-thermostat operation
onto Manual mode (closing the contact), to then be able to operate
on the device it will be necessary to make another phone call to have
the input contact open.

8. BUTTON FUNCTIONS
The surface-mounting timer-thermostat 01911 is used and pro-
grammed with:
• the selection button;
• the rotary knob;
• the vertical sliders.
8.1 selection button
The push-button, pressing it briefly, is used to confirm selections
when scrolling through the menus or to confirm actions of program-
ming; pressing and holding it down, instead, accesses or exits the
menu. In addition, in some cases, it can also be used to pass from
one operating mode to another (for example from Automatic to
Manual).
8.1.1 Pressing the selection button
• When the timer-thermostat displays the information related to a
general operating mode (Manual, Automatic, OFF, etc.), on quickly
pressing the push-button, the device:
- switches onto Manual if it was operating in a different mode;
- switches onto the previously active mode if the timer-thermostat
was operating in Manual mode;
- if it is on, it deletes the automatic temperature change.
Pressing the selection button for approximately 4 s when the
timer-thermostat display shows the information related to any
operating mode accesses the device’s programming menus.
• When the display shows the timer-thermostat programming
menus, quickly pressing the button confirms access to the menu
displayed, then accessing the related submenus.
Pressing the selection button for approximately 2 s when the
timer-thermostat display shows the programming menus exits
these menus and the device returns to the currently active
operating mode.

12
8.2 Rotary knob
Turning the knob clockwise or anticlockwise scrolls through the vari-
ous menu items and allows setting the parameters during the phase
of programming (temperature, date, time, etc.).
• If the timer-thermostat is working in Manual mode, turning the knob
changes the temperature setting.
• If the timer-thermostat is working in Automatic mode, turning
the knob accesses the procedure for setting the Automatic
Temperature Change (see par. 9.4.2).
In the other operating modes, turning the knob produces no effect.
8.3 Vertical sliders
Using the 22 sliders that are accessed by opening the front of the
device it is possible to:
- set the desired temperature when the timer-thermostat is on daily
Automatic mode;
- set the desired temperatures, for each hour and for each day of the
week, while configuring the weekly automatic program.
Slider adjustment has immediate effect when the timer-thermostat
is working on daily Automatic mode; if this is not the case, there
will be no change.
Take care that, if the operating mode is then switched over onto
daily Automatic mode, the temperature values will adjust to the
current position of the sliders.
Whereas, if operating in weekly Automatic mode, the timer-
thermostat will set the temperature values defined in the program-
ming phase and changing the sliders will not make any change
(unless, after opening the front, you confirm the intention to edit
the program).

9. ACCESS TO MENUS AND OPERATING
MODES
This chapter illustrates the procedures to follow in order to set and
program the timer-thermostat and the related operating modes.
When the display shows a general operating mode, press the
selection button for approximately 4 s; this takes you to the main
menu whose items can be displayed by turning the knob:
• OFF
• OFF TIMED
• ANTIFREEZ.
• AUTO
• MANUAL
• MAN TIMED
• SETTINGS
• BACK
After entering a menu, if no operations are performed within a
time of approximately 40 seconds, the timer-thermostat will exit
this menu without saving any settings made in the meantime.
In all the menus, selecting the BACK, option will take you back
to the previous display.
Note: The SETTINGS. menu is the menu that enables setting the
language, date, time, operating mode of the automatic program
(daily or weekly), password, etc.

9.1 OFF
When the timer-thermostat is OFF, the device is off.
The display will in any case keep on showing the date, time and
room temperature.
Access the main menu and press the selection button in cor-
respondence with OFF; the timer-thermostat is switched off and
as a result you exit the menu. The device will no longer make any
adjustment and the display will show:
9.2 OFF TIMED
This option permits switching off the timer-thermostat for any length
of time at the end of which the device will switch on, going back into
the previously active operating mode (that is before switching off).
The OFF TIMED mode cannot be accessed if the timer-thermo-
stat is working in OFF or MAN TIMED mode.
Access the main menu and press the selection button in cor-
respondence with OFF TIMED; the display will show:
Figure 12 Figure 13

15
Using the rotary knob, set the desired time interval.
The value can be set in the range from 1 hour to 1 year in steps
of one hour; the first 6 hours are displayed as shown in figure 22
whereas after the 6 hours the display will show the date and time
within which the OFF TIMED operation will end.
The following figure, by way of example, shows the screen corre-
sponding to the OFF TIMED mode that will remain active until 18th
January at 11:30 a.m. after which the timer-thermostat will switch
over onto Manual mode.
The messages current date/time and date/time will appear alternate-
ly on the display as long as the OFF TIMED mode stays active.
Then press the selection button to confirm.
Note: To exit the OFF TIMED mode quickly, just briefly press the
; selection button; you will thus go into MANUAL mode (press-
ing the button a second time will set the OFF mode).

9.3 ANTIFREEZ.
This option, which can only be set on heating, permits setting a
minimum temperature level so as to avoid damage to the pipes or to
prevent the temperature from falling under a safety level; when the
room temperature drops under the set antifreeze value, the timer-
thermostat will switch on.
Access the main menu and press the selection button in cor-
respondence with ANTIFREEZ.; the display will show:
Using the rotary knob, set the desired antifreeze temperature; this
value can be set in the range from 4 °C to 15 °C in steps of 0.1 °C.
Then press the selection button to confirm.
9.4 AUTO
In the AUTO operating mode, that is automatic, the timer-thermostat
performs temperature control (both for heating and air-conditioning)
by comparing the room temperature with the setting for each hour
of the current day.
Access the main menu and press the selection button in cor-
respondence with AUTO; the display will show:
Press the selection button again to confirm.
