3 - INSTALLATION GUIDELINES

Chronothermostat installation: independent-fixed

• Wall mounting - in round box - semi-recessed in rectangular box of 3modules.
• Install the device approximately 1.5 m off the ground well away from sources of heat, windows and anything else that can affect its normal state of operation.

4 - ATTACHING THE BASE TO THE WALL

• Switch off mains power to device
• Using screws, attach the base to the wall, to the round or rectangular built-in box using the appropriate pairs of holes A.
• If the wall where the base of the chronothermostat is to be attached is metal, insert the insulating washers into the two screws.

A - attachment holes
B - wire passage from round, rectangular box
C - chronothermostat attachment teeth

To ensure the chronothermostat is correctly fitted to the base on the wall, it must not in any way be buckled due to over tightening the screws fixing to the rectangular or round box built into the wall.

5 - ELECTRICAL CONNECTIONS

Important: Installation and electrical connections of devices and appliances must be carried out by skilled people and in compliance with current regulations. The manufacturer declines all responsibility for the use of product that must conform to specific environmental and/or installation standards.

Note for the installer: If surface mounting (e.g. on a wall), have suitable raceways for the cables in compliance with current standards. Check that the relay load does not exceed the figure given in the technical data.

• Switch off mains power to the device.
• Connect the device to be controlled to the terminals:
  1 - common
  2-normally closed contact
  3-normally open contact

11 - DISPLAY/MODIFY SET TEMPERATURES (via knobs): tCOMFORT / t ECONOMY

The display normally shows room temperature detected or current hours and minutes.

upon first start-up of the chronothermostat or after reset operation, preset default temperatures are:

Comfort Temperature Set t ^* = 20.0 °C/68.0°F (upper knob) Economy TemperatureSet t C = 17.0 °C / 62.6 (lowerknob)°F

In any chronothermostat operating condition, to display the current settings, simply slightly turn the relative knob until the set itself blinks. After 5 sec., the display will return to normal operation visualisation. If settings do not meet user needs, it is possible to modify them as desired at any time, from +5°C to +30 °C(from +4°F to +86°F), as per procedure shown to the side.

Perform the same procedure to set the Seteconomy temperature with knob tc

12 - COMFORT AND/OR ECONOMY TEMPERATURE MAX SET LIMIT (LOCKED SETTING)

In some particular installations, for instance in public offices, hotels, etc., it may be useful to lock the chronothermostat temperature settings to avoid incorrect settings being entered by unauthorised personnel. It will then be possible to lock the maximum Set temperature values (comfort and/or economy) as

It will then be possible to look the maximum set temperature values (comfort and/or economy) as follows:

1 - Move the switch to anti-freeze mode t (set fixed at +5°C, not adjustable)
2- Press the h23 button on the ring and the ⏻/¶ button simultaneously for 4 sec.; the display will show: b i : - (i.e. default setting = no lock).
3- Slightly turn the desired set knob (t* or t c) to view the current setting.
4- The Set will start to blink. After 3 sec., set the block setting (limit) from +5,1°C to +29,9°C, turning the knob clockwise to increase or counter-clockwise to decrease (a variation of 0.1°C at a time will be obtained).
5- If desired, repeat the operations indicated in points 3 and 4 with the other hand piece.
6- Within 20 sec., save the setting/s and exit from programming, pressing the h 23 button on the ring and button Ⓞ/☐ simultaneously for 4 sec.
7- Bring the switch back to the desired operating mode.

The settings of the microswitches (dip-switches) on the back of the chronothermostat must be made by qualified personnel.

13 - TEMPERATURE DIFFERENTIAL

The chronothermostat works in ON-OFF differential mode (Dip 3 OFF) with the default differential setting of (0,54°F)0,3°C . The differential can be changed by moving the microswitches (dip-switches) as shown in the table.

ON OFF

Dip 1	Dip 2	Dip 3	Differential
OFF	OFF	OFF	0,3 °C (0,54 °F)
OFF	ON	OFF	0,5 °C (0,9 °F)
ON	OFF	OFF	0,7 °C (1,26 °F)
ON	ON	OFF	0,9 °C (1,62 °F)

The differential must be set according to the system's thermal inertia; a low setting is recommended for systems with radiators (e.g. made of cast iron) and a high setting for systems with fan-coils.

14 - PROPORTIONAL OPERATION

As an alternative to the differential, it is possible to adjust the temperature proportionally (Dip 3 ON); this system enables saving on energy consumption and also on the wear of the burner by limiting the number of ignitions. The duration of each ignition depends not only on the set cycle but also on the difference between the set temperature and the measured temperature (see example).

Example of setting t = 20°C - Cycle = 10 min

t = 20,5 °C Consumer alwaysOFF
t = 20,4 °C Consumer 1 min ON - 9 min OFF
t = 20.3 °C Consumer 2 min ON - 8 min OFF
t = 20.2 °C Consumer 3 min ON - 7 min OFF
t = 20.1 °C Consumer 4 min ON - 6 min OFF
t = 20.0 °C Consumer 5 min ON - 5 min OFF
t = 19.9 °C. Consumer 6 min ON - 4 min OFF
t = 19.8 °C Consumer 7 min ON - 3 min OFF
t = 19.7 °C Consumer 8 min ON - 3 min OFF
t = 19.7 °C Consumer 8 min ON - 2 min ON t = 19.6 °C Consumer 9 min ON - 1 min OFF
t = 19,6 °C Consumer 9 min ON - 1 min OFF
t = 19,5 °C Consumer always ON

The duration of the cycle is determined by the position of the microswitches (dip-switches) on the back of the chronothermostat, as shown in the table. A long cycle is recommended for systems with high thermal inertia (cast-iron radiators, floor systems) and a short cycle for systems with low thermal inertia (fan-coils).

Dip 1	Dip 2	Dip 3	Duration Cycle
OFF	OFF	ON	7 min
OFF	ON	ON	10 min
ON	OFF	ON	15 min
ON	ON	ON	20 min

15 - TEMPERATURE SCALE °C or °F

ATTENTION: the chronothermostat is preset to operate in Celsius degrees and can be modified by the installer or an expert user to function in Fahrenheit degrees (°F).

Microswitch in the back of the chronothermostat is default set to the position (Celsius degrees).

It can be moved to the ON position: the display, after performing a RESET operation, will show room and Set temperature in Fahrenheit degrees(°F).

To return to Celsius display, bring microswitch 4o the OFF position and perform a RESET operation.

In both cases, reprogramme the chronothermostat as indicated in chapter 10).

OFF = Celsius degrees (°c) range (default setting)

ON = Fahrenheit degrees (°F) range

16 - WARNINGS
