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
easy menu navigation for programming the chronothermostat and selecting
the various operating modes.

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 defined in the relative
time bands of the programmed ambient profile. The comfort and economy
times can be defined 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 first switchover at 7.00 am
• reduction to "economy" temperature, with the first 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 defined 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.
