TRAVEL function
In the event of a prolonged absence, you can set the
temperature for that period (or even the closure of the
valve), along with the date and time of your return.
CHILDREN LOCK function
This function allows to deactivate the multifunction buttons
and wheel selector to prevent unauthorised persons from
accessing the menu.
Restoring the factory congurations
This function allows you to delete all the programming
operations made and thereby restore the chronothermostat
to the conditions of the initial factory programming.
Automatic protection functions
Regardless of the programming and operating modes, the
chronothermostat has two automatic protection functions:
• Anti-freeze function: if the room temperature falls below
6 °C, the chronothermostat opens the valve until the
temperature rises to 8 °C. This prevents the water in the
pipes from freezing.
• Anti-calcication function: once a week, on Friday
morning, the chronothermostat performs a valve opening/
closing cycle to prevent the valve from calcifying.
TIMER function
With this function a certain temperature can be set for a
predetermined time interval. Press the button.
First the time in which the program is activated is shown.
Conrm with OK button.
Now, the desired temperature can be set. Conrm with OK .
During the selected time period is not possible to change
the temperature manually.
With the MENU button the function is disabled.
OFFSET setting
Elements like shelves and curtains near a radiator can
impede good heat diusion, inevitably aecting the room
temperature detected by the chronothermostat and its
subsequent adjustment.
In these cases, if the room temperature is very dierent
from the temperature set on the chronothermostat, you
can insert a correction factor, called OFFSET.
NOTA. Before implementing an OFFSET value, it is necessary to measure
the room temperature with the aid of a precision thermometer.
Example: if the “comfort” temperature set on the chronothermostat is 21 °C
but the real temperature in the room is only 19 °C, enter a correction factor
of +2 °C.
OPEN WINDOW function
When the window is opened and the temperature therefore
drops suddenly, the chronothermostat temporarily closes
the valve (for a presetted time) to save energy.
During this time, the anti-freeze symbol will be shown on
the display.
At the end of the timed period, the chronothermostat
returns to normal operating mode.
Heating shut-o (valve closure)
If necessary, you can close the valve to deactivate the
heating in a room. The valve closes and thereby deactivates
the heating function, but the anti-calcication function still
remains active.
By resetting AUTO mode at any time, the chronothermostat
will start up again and implement the programmed prole.
Manual mode (MANU)
In manual mode, the chronothermostat adjust the
temperature set throught the wheel selector.
Operation
Automatic mode (AUTO)
In automatic mode, the chronothermostat adjusts the
temperature on the basis of the “comfort” or “economy”
functions dened in the relative time bands of the
programmed ambient prole.
The comfort and economy times can be dened via
programmed timing. Up to 8 daily switchovers can be
selected (4 “comfort” and 4 “economy”).
The chronothermostat has the following factory settings:
• heating at “comfort” temperature, with the rst switchover
at 7.00 am
• reduction to “economy” temperature, with the rst
switchover at 10.00 pm
In this way, one daily heating time band is set (from 7.00 am
to 10.00 pm) for the whole week.
Setting the comfort/economy times
Up to 4 daily “comfort” switchovers (heating active) and 4
“economy” switchovers (temperature reduction) can be
dened for each of the 7 days of the week, or for 3 groups
of several days.
In the menu, the indications DAY1÷DAY7 refer to the days of
the week (from DAY1 Monday to DAY7 Sunday).
The days are also shown in abbreviated form (Mo, Tu, We,
Th, Fr, Sa, Su) beneath the hourly timings bar.
The indications D1-5, D1-6 and D1-7 refer to groups of
several days, allowing you to quickly program a number of
days at the same time:
• D1-5 = group of days from Monday to Friday
• D1-6 = group of days from Monday to Saturday
• D1-7 = group of days from Monday to Sunday
NOTA. Any days that are not programmed remain set with the factory
values. The “comfort” and “economy” temperatures are factory-set at 21 °C
and 16 °C respectively.

Installation and removal of the chronothermostat
Allowed installation positions
 This position is not recommended due to the inuence of the radiator temperature on the chronothermostat.

Preparation for installation
On the display PREP will be shown.
Now, the motor will move to the installation position in order to make the installation easier.
As soon as K470H chronothermostat is ready for installation, INST will be shown on the display.
Installation on Giacomini valves with thermostatic
option, with connection M30 x 1,5 mm (H series)
Tighten the ring nut (B) of the chronothermostat on the
radiator valve (A).

Installation on other Giacomini valves with thermostatic
option, except DB series valve
When installing on other Giacomini valve bodies with
thermostatic option, use the contents of the sachet
R453HY012 (included in the chronothermostat package).
Fit the threaded ring nut (C), coupling it with the reference
pins (P) on the radiator valve (D).

NOTE. The chronothermostat must be in INST or ON mode in order to x it
to the ring nut without too much effort.
If the chronothermostat is installed at a later time, select the INST menu
before xing it to the ring nut.

Adaptation on the valve
Initial installation: press the MENU button until and roteta the wheel selector unitl ADAP appears on the display.
Press OK button. The chronothermostat will adapt to the stroke of the valve.
This can take a few minutes.
Once the adaptation is nished, the chronothermostat returns to normal mode.
If another adaptation is required, for example if the valve did not close completely during the rst adaptation, select ADAP
after pressing the MENU button and restart the operation.
Removing the chronothermostat
To remove the chronothermostat:
• Set the maximum temperature with the wheel selector (the display will show ON) and wait at least one minute.
• Unscrew the ring nut (B) of the chronothermostat from the radiator valve.

Programming via K471 key
The K470H chronothermostat can be directly programmed via the K471 programming key, ensuring quick and easy
chronothermostat conguration thanks to the exchange of data via the Mini-USB connector.
Using the key K471 and viewing the graphic interface on the PC, you can easily programme the daily time bands for the
“comfort” (Tmax) and “economy” (Tmin) temperatures of the chronothermostat.
Once the temperature proles of the various rooms have been stored on the key K471, they can be uploaded onto the
chronothermostat K470H which thus automatically acquires the current time and date.
This means that any pre-setting by the user is superuous.
NOTA. Initial chronothermostat start-up. The transfer of the weekly prole to a chronothermostat presupposes that the device is already installed on the valve,
as its good functioning depends on the positive outcome of the initial start-up sequence.
For more details, refer to the installation and user instructions of the K470H chronothermostat.
The standard indications disappear from the display and are replaced with the code P01 (Ambient prole 1).
Using the chronothermostat selector wheel, select the required ambient prole; choose the numerical index of the ambient
prole from those previously programmed with the software.
When you press the OK button, the parameters of the selected prole are transferred from the key to the chronothermostat.
As soon as the chronothermostat has been programmed, the standard information returns to the display.
Insert the Mini-USB connector of the K471 key in the relevant connector on the side of the K470H chronothermostat.
NOTA. If the list of ambient proles is not viewed via the chronothermostat
wheel within 10 seconds, the display will resume the usual indications.
In this case (and if necessary), take the key out and then insert it again.
