Operation
Manual mode
In manual mode, the chronothermostat adjust the temperature set via the
wheel selector.
Auto mode (automatic program)
In automatic program 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 eight daily switchovers
can be selected (four“comfort” and four “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 four daily “comfort” switchovers (heating active) and four “economy”
switchovers (temperature reduction) can be dened for each of the seven
days of the week, or for three 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
Note:
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.
Description
The K470H chronothermostat for radiators is a technologically advanced
device that is quiet and compact - it measures no more than a normal
thermostatic head. The K470H chronothermostat is equipped with a ring nut
with standard thread M30x1,5 mm and one adaptor, for use with a wide range
of radiator valves. The function keys, wheel selector and LCD display enable

C+D
Note:
The chronothermostat must be in“INST”or “ON” mode in order to x it
to the ring nut without too much eort.
If the chronothermostat is installed at a later time, select the “INST”
menu before xing it to the ring nut.
To ensure better temperature adjustment, you are advised to install
the chronothermostat with the display facing upwards.
Removing the chronothermostat
To remove the chronothermostat from the ring nut:
• Set the maximum temperature via 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.

Advanced functions
TIMER function
The timer function is selected with the timer-button .
With this function a user-dened temperature for a programmable period can
be entered. This can be very useful in case of a party, for example. Press
First, the time for which the time programme has been deactivated is shown.
Conrm with OK Now, the desired temperature can be set. Conrm with OK
. In the selected period it is not possible to change the temperature manual, the
wheel is locked. Press Menu and unlock it.
Setting the OFFSET
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):
Note:
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.
WINDOW function
The chronothermostat has an “open window” function: when the window is
opened and the temperature therefore drops suddenly, the chronothermostat
temporarily closes the valve (for a set 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.
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 SAFETY function
This function allows you to deactivate the keys and wheel selector to prevent
unauthorised persons from accessing the menu.
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.
Restoring the factory congurations
With this function, you can delete all the programming operations made
and thereby restore the chronothermostat's initial factory programming
conditions.
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.

K471
Programming key for chronothermostat for radiators (K470H series). USB
connection to the PC and Mini-USB to the chronothermostat. 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.
Programming via key K471
The chronothermostat can be directly programmed via the programming
key K471, 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.
Note:
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
chronothermostat K470H.
Insert the “Mini-USB”
connector of the
programmer in the
relevant connector
on the side of the
chronothermostat.
The standard indications disappear from the display and are replaced with
the code “P01” (“Ambient prole 1”).
Using the chronothermostat knob, 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” key, 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.
Note:
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.
