3 INSERTION AND REPLACEMENT OF BATTERIES

Insert 2 AA 1.5 V alkaline long lasting batteries, of a good brand, paying attention to the marked polarities.

N.B. the life of the batteries is greatly affected by the type of use and the settings made by the user, especially the brightness of the display.

When the batteries are low, the symbol of the discharged battery flashes on the display: CH191 keeps working regularly.

If the batteries are completely discharged, the chronothermostat quits working (switching off the system) and the display reads "REPLACE BATTERIES", until the batteries are replaced.

To remove the batteries, extract CH191 from its housing pulling it upwards.

When you disconnect the chronothermostat, the text “Disconnected” is displayed for one minute as well as the symbol of the battery flashing (the battery symbol also flashes, but differently, when the batteries are charged, signalling that the body of the chronothermostat is disconnected from the base). The text “Connected” disappears when you press a key. All parameters remain stored while the batteries are being replaced.

4 MAINTENANCE

Use only a soft cotton cloth to clean the chronothermostat without any detergent. Do not use paper tissue to clean the screen.

KEYBOARD BLOCK

To make sure you don't change any settings on the chronothermostat unintentionally while cleaning, enable the keyboard block by pressing the middle of the display for 5 seconds. The text "BLOCKED" appears on the display when the keyboard has been blocked. The keys will re-enable automatically after 30 seconds.

5 QUICK GUIDE FOR PROGRAMMING

DESCRIPTION OF KEYS/DISPLAY

The chronothermostat is equipped with 6 keys, the function of which varies depending on the situation. It is described by the symbol which appears on the display next to the key.

N.B.: to switch on the display, press in the middle; if no other keys are pressed, the display switches off after 2 seconds; if other keys are pressed, the display will switch off after remaining idle when the time set in the parameter LIGHT ON expires (see Chap. 6 CONFIG. PG03).

SETTING TIME AND DATE

After the device switches on, press the key PROG briefly: the text "Setup" is displayed; now press ▶ to enter the "Hours" page. Set the hour by pressing ▲ and ▼ Then press ▶ to go to the "Minutes" setting.

Again press ▶ to select, in order, the Year, Month and Day.

Pressing again allows you to choose whether to disable automatic change of summer/winter time: initially this function is active can but can be deactivated by pressing "NO" using the keys ▲ and ▼ Pressing ◀ allows you to go back to the previous page. To exit the Setup menu, pressENTER.

OPERATING PROGRAMS

The CH191 chronothermostat has different operating modes, called programs:

■ "AUTO" WEEKLY PROGRAM:

one of the four programmable temperatures can be associated to each half hour for each day of the week. This is the program displayed when the chronothermostat is switched on and is generally the one most used.

■ "HOLIDAY" DAILY PROGRAM:

Like in the AUTO program, you may select one of the 4 programmable temperatures for each half hour, but the identical sequence will be repeated every day.

CH191

■ "JOLLY" TEMPORARY PROGRAM:

you may choose to hold a certain temperature for a certain number of hours, after which it will go back to the previously active program.

■ "MAN" MANUAL PROGRAM:

the chronothermostat maintains a fixed temperature, for an unlimited amount of time until another program is selected.

■ SYSTEM OFF OR WITH ANTIFREEZE PROGRAM "OFF/ANTIFREEZE":

the system remains off or else maintains a very low temperature (from 2 to 7°C) to prevent the fluid in the heating system from freezing.

SETTABLE TEMPERATURES

Four different temperatures can be set and one can be selected for each half hour of the day in the AUTO and HOLIDAY programs. Three of these temperatures (T1, T2 and T3) can have values from 2^ to 40^ C, while the fourth, T antifreeze (TA), can range from 2^ to 7^ C, or be set at “OFF” (system off). The manual program has its specific temperature (TMan), like the JOLLY program (Tj), which are set in the respective screens and can range from 2^ to 40^ C.

The ANTIFREEZE/OFF program, on the other hand, follows the temperature TA which, as we have said, can range from 2° to 7°C; or else, it can be set at “OFF”, switching the plant completely off.

SETTING OPERATING PROGRAMS

→ PROGRAM SELECTION

press SEL to select, in cyclical sequence, the different operating programs: AUTO -> MAN -> OFF -> HOLIDAY.

PLEASE NOTE: the JOLLY temporary program is not included in the program sequence, but can be selected directly by pressing the JOLLY key.

→ SETTING THE TEMPERATURES

press TEMP in the AUTO, HOLIDAY and OFF programs to change the value of the 4 programmable temperatures: when you pressTEMP several times, the values T1, T2, T3, Ta appear in sequence; stop at the T you want to change and use the arrow keys ▲ and ▼ to increase or decrease the temperature by

a tenth of degree at a time. Press ◀ to go back to the initial status. Remember that T1 will always be less than T2, and T2 than T3.

Pressing TEMP in the JOLLY program allows you to modify its temperature using the keys ▲ and ▼Press to go back to the page displaying the hours, allowing you to modify them using ▲ and . ▼

The MAN program allows you to modify the fixed temperature TMan using the keys ▲ and ▼

→ EDITING CURRENT DATE AND TIME

Press PROG briefly to enter the "SETUP" menu. Using ◀ and ▶ allows you to modify: winter/summer, hours, minutes, year, month, day, summer time.

These values can be changed using the keys ▲ and ▼

→ CUSTOMISATION OF WEEKLY "AUTO" PROGRAMMING AND DAILY "HOLIDAY" PROGRAMMING

Keep the key PROG pressed until the text "Config" is displayed. This menu allows you to program the weekly profiles (AUTO program) and daily profiles (HOLIDAY program) and to set the advanced functions (see the following paragraphs for their description).

PLEASE NOTE: if the text "Setup" appears instead of "Config", you did not press the key long enough and you must press ENTER to go back to the normal operating condition and try again.

When you enter the “Config” menu, a page appears which allows you to choose the desired temperature (T1/T2/T3/Ta) for each half hour of the indicated day (from 1 to 7 indicating the days from Monday to Sunday).

PLEASE NOTE: T1/T2/T3/Ta are displayed on the right of the screen with the symbols

$$ \varepsilon 1 - \varepsilon 2 - \varepsilon 3 - \varepsilon 8 $$

Pressing ◀ and ▶ allows you to move one half hour at a time to the right or to the left.

Pressing ▲ and ▼ allows you to go from one programmed temperature to another.

Pressing PROG (briefly) switches you to the next day (DAY 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> H).

PressCOPY to copy the temperature profile of the current day on the following day.

After H (profile of the Holiday daily program) you go to the Correction parameter page.

Then pressing ENTER from the Correction page allows you to the exit the "Config" menu.

N.B.: press ◀ at the start of day 1 to go right to the Correction page.

→ "JOLLY" PROGRAM SETTING

In all programs, except MAN, pressing the key JOLLY selects the temporary program: this program allows you to define the desired temperature and its duration in hours (up to a maximum of 240, so to say 10 days).

For example, you may want to keep a lower temperature during the entire weekend when no one is home.

When you enter this program, you may modify the duration, which initially is one hour, and increase the number of hours by pressing ▲, or decrease them by pressing ▼.

Pressing TEMP allows you to view and modify temperature Tj, again using the keys ▲ and ▼

Pressing ◀ sends you back to view the duration of the JOLLY program.

When this time elapses, you go back to the initial program.

→ "OFF/ANTIFREEZE" PROGRAM SETTING

Pressing OFF from any program switches the chronothermostat to the off/antifreeze status. The antifreeze temperature (Ta) can be programmed by pressing TEMP, from OFF (boiler always off) to an interval between 2.0 and 7.0°C, using the arrow keys ▲ and ▼

Go back to the OFF status by pressing ◀.

Pressing OFF again sends you back to the previous operating status.

→ ALTERNATIVE DISPLAYS

Other information can be viewed in the AUTO and HOLIDAY programs in place of the temperature profile, by pressing the keyDISP several times.

The first time it is pressed the programmed temperature for the current half hour appears, the second time it displays the date, the third time it displays the temperature of the external probe and the fourth time it goes back to the initial temperature profile.

6 FUNCTIONS IN DETAIL

AVAILABLE PROGRAMS

CH191 has several operating modes (programs):

■ "AUTO" weekly program
■ "HOLIDAY" daily program
■ “JOLLY” temporary program
■ “MAN” manual program
■ system off or with antifreeze "OFF" program

→ "AUTO" WEEKLY PROGRAM

4 temperature levels can be used in the AUTO operating mode (Ta, T1, T2, T3), according to a programming with 30 minute steps, 24 hours a day, 7 days a week. The days are numbered from 1 to 7 and correspond to the seven days of the week, starting from Monday.

To simplify programming, you may set the first day and copy it on the following days. The default for days 1 – 5 (Monday to Friday) is:

00:00 - 06:30 T1

06:30 - 09:00 T2

09:00 - 11:30 T1

11:30 - 14:00 T2

14:00 - 17:00 T1

17:00 - 22:30 T3

22:30 - 24:00 T1

while the default for days 6 and 7 (Saturday and Sunday) is:

00:00 - 08:00 T1

08:00 - 11:30 T2

11:30 - 23:00 T3

23:00 - 24:00 T1

The value of the 4 temperatures can be programmed using the TEMP function. The temperature profile (hourly variation) can be programmed using the PROG function.

→ "HOLIDAY" DAILY PROGRAM

4 temperature levels can be used in HOLIDAY operating mode, according to a programming with 30 minute steps, 24 hours a day.

This achieves a daily programming, regardless of the days of the week. The default temperature profile is:

00:00 - 08:00 T1

08:00 - 11:30 T2

11:30 - 23:00 T3

23:00 - 24:00 T1

The value of the temperatures can be programmed using the TEMP function.

The temperature profile (hourly variation) can be programmed using the PROG function.

→ JOLLY

The JOLLY mode allows you to set a programmable temperature (Tj) for a programmable number of hours (from 1 to 240). It is used when you wish to introduce a temporary variation to programming without changing the parameters, for example to maintain a high temperature for longer when spending an evening with

friends or to keep it low when no one is home the weekend.

If you enter JOLLY mode using the specific function key, when time is up it goes back automatically to programming in progress.

→ MANUAL

MAN mode allows you to set a fixed temperature manually (Tman), ranging from +2.0 to +40.0 degrees, without expiring and without needing to modify the weekly or daily program.

For example it can be used to keep the house at a different temperature than that of the daily program when no one is home, or to switch on the system remotely, bringing it to a constant temperature.

→ OFF

OFF mode is used when you want to switch the system off.

It uses the temperature TA (antifreeze) as a reference, to guarantee protection of the system at low temperatures.

TA is normally set at +5 degrees, but it can also be set at OFF, to switch the boiler completely off. Weekly or daily programs remain unchanged.

SETTABLE TEMPERATURES

The system can use 4 different temperature levels, three for normal use and one, called “antifreeze”, to be used when you wish to keep the boiler off, but without risking having the fluid in the system freeze.

Programming of the three T is conditioned by reciprocal values:

T1 cannot be higher than T2,

T2 cannot be higher than T3.

The temperatures are set using the keyTEMP and ▲ and . ▼

T1 ranges between +2.0 and +T2 degrees, with variations every tenth of degree [default 17.0].

T2 ranges between +T1 and +T3 degrees, with variations every tenth of degree [default 19.0].

T3 ranges between +T2 and +40.0 degrees, with variations every tenth of degree [default 20.0].

TA (antifreeze) ranges between +2.0 and +7.0 degrees, with variations every tenth of degree, or a can be OFF, when the boiler remains off [default 5.0].
