Modes of operation The chronothermostat CH150/151/152 has 4 different modes of operation — Manual, Automatic, Holiday and Jolly — and OFF mode. Manual mode of operation In the Manual mode of operation, the chronothermostat regulates the operation of the heating or cooling plant to maintain the same temperature always. To select Manual, press the key MAN.
Holiday Mode of Operation In the Holiday mode of operation, the chronothermostat CH150 regulates the operation of the heating or cooling system following a single temperature pattern which is the same each day. To select Holiday mode, press the HOLIDAY key.
«Programming the chronothermostat». Jolly Mode of Operation In the Jolly mode of operation, the chronothermostat CH150 interrupts its current mode and regulates operation of the heating or cooling system to maintain the “Jolly” temperature during the whole time entered (from 1 hour to 99 days and 23 hours, in one hour steps).
To set the hours («h») of duration of Jolly operation, central rotary selector switch. The hours can be set in the range from 0 to 23. To set the days («d») of duration of Jolly operation, use the top rotary selector switch.
The plant switches off completely and the wording OFF appears on the display, with no temperature pattern. Preset Programmes The chronothermostat CH150 is supplied with two preset programmes, one winter and the other summer, so that it can be put into operation quickly. Winter programme – weekdays (Monday to Friday) Winter programme –...
Programming the chronothermostat It is possible to personalise the temperature patterns for Automatic and Holiday modes to bring them into line with one’s personal requirements. To enter new temperature patterns, proceed as follows. 1. Enter the main page of the programming menu; the current mode of operation is temporarily interrupted.
5. Press the ENTER key to move to the next day and repeat the steps from point 2 for the other days of the week; the Holiday pattern is indicated as DAY 8. To return to the main page of the programming menu, use the ENTER key to scroll all the eight days or keep the ENTER key pressed for 3 seconds.
Statistics The chronothermostat CH150 provides a set of statistical data on operation of the plant. To access these data proceed as follows: 1. Enter the main page of the programming menu. The mode of operation in use is temporarily interrupted. Select the statistics function.
5. Page 4: maximum temperature reached during the current day and the hour when it was reached (in the diagram 22.5 °C at time 21.08). 6. Press the ENTER key twice to return to the mode of operation previously in use. Maintenance To clean the chronothermostat, a soft cotton cloth with no detergent is recommended.
Installation Note. Installation should be performed only by qualified personnel, complying scrupulously with current regulations. Installation of the chronothermostat comprises the following stages. • Fixing of the base • Electrical connection. • Insertion of the batteries. • Fixing the chronothermostat to the base. •...

Period of regulation Imposes the duration of the regulation cycle (period on + period off) when the proportional temperature regulation mode is chosen. Select 5 minutes for low inertia plants (such as fan coils), 10 minutes for medium inertia plants (such as aluminium radiators), 20 minutes for high inertia plant (such as cast iron radiators).
Display of relative humidity 20% - 90% The device Chronothermostat CH150 conforms to standards CEI EN 60730-1 and second parts. Fantini Cosmi S.p.A. reserves the right to make all the technical and construction changes it considers necessary, with no obligation to advance notice.
