ELECTRONIC PROGRAMMABLE THERMOSTAT CRONO.X
Read all the instructions carefully
CRONO.X
is a weekly programmable thermostat that unites
ease of use
with
some
innovational functions
not featured by traditional household temperature
controllers.
More
specifi cally, this device is singled out by 6 features:
1)
It
displays
or
controls
the temperature in a room situated at a maximum
distance
of
40m
by the use of an optional sensor (mod. X.Temp cod. VN883500)
2)
A
settings
guard
function is available in order to avoid unauthorized tampering
when the device is used in
public premises
.
3)
The
system’s on-off status
can be
remote-switched by landline or cellular
GSM phone
. This is especially useful when the house is not used permanently or
it is a holiday home.
To implement this function it is necessary to install a device that receives calls
or SMSs and interfaces with the programmable thermostat (phone dialer mod.
VN782900 X.Code Wave for landline phone, VE072500 X.Code Bus for GSM
network)
4)
Daylight saving time/solar time switching
can be
automatically enabled
or disabled
5) The cut-in differential can be adjusted from
0,1°C to 1,0°C
6) Temperature control can be set to
ON/OFF mode or Proportional mode with
selectable band and periods, the latter being especially appropriate in
very large rooms with a strong thermal drift
(sheds, systems including
fan-coils, aluminum or cast-iron radiators, etc.)
Also, when in
manual mode, CRONO.X
works as an ordinary thermostat.
Conversely, when in
automatic
mode: one of the three user-defi ned temperature
levels can be chosen for each hour segment of the day.
CRONO.X
controls
both
heating
and
air-conditioning systems
.
