calcification protection programme once a week on Friday mornings.
CLEANING AND USED DEVICES
Cleaning
To clean the K470H use only a dry or lightly wet cloth.
Avoid chemical solvent – it can probably damage the device.
Used devices
Do not throw old devices and packaging into the household waste.
They can be recycled. You receive further information at your local
government.
PROGRAMMING VIA K471 KEY
The K470H chronothermostat
can be directly programmed
via the K471 programming key,
ensuring quick and easy chron-
othermostat configuration
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 profiles of the various rooms have been stored
on the K471 programming key, they can be uploaded onto the K470H
chronothermostat which thus automatically acquires the current time
and date.
This means that any pre-setting by the user is superfluous.
For the programming, refer to the instructions enclosed with the K471
programming key.
The device’s Mini-USB connector is only compatible with the cable
of the programmer K471; do not connect any other devices fitted
with a Mini-USB connection, as this could irreversibly damage the
chronothermostat.

warm up.
Is the boiler water
temperature O.K.?
Valve does not open,
is it calcifi ed after
the summer pause /
heating pause?
Adjust the temperature
of the boiler water.
Remove the K470H,
move the valve
stem back and forth per
hand or with a tool.
Heating ele-
ment

“Adapting”) Move the
valve stem several times
by hand, it may be that
adaptation is impossible
because your valve is
calcifi ed or the seat
no longer performs its
function.
Pressure
piece falls
out (This can
also cause
an E1-error)
Due to an endlessthread
