*NOTETheSIMused must conformtotheGSM11.12phase 2+ standard(in
practice, any SIM of regular mobile operators but not the USIMs of mobile
operator: TRE). It must be linked to a top-up voice with SMS contract (if
necessary, verify the credit) or with a subscription contract and the PIN
code must be disabled.
Before inserting the SIM card it is advisable to verify that it works by using
it in a mobile phone and trying to send and receive an SMS.
After inserting the SIM and switching the CH140GSM on, any SMS
messages that have not yet been delivered or sent in the first moments of
operation will be cancelled.
ATTENTION: the 2 auxiliary inputs must be connected to contacts that are
dry and voltage-free and with cables no longer than 3 m.
GSM FUNCTIONALITY VERIFICATIONS
The programmable thermostat connection to the GSM network can be
detected by the antenna symbol and three bars.
The antenna symbol flashes if the module is not registered to the GSM network
(e.g. no coverage, SIM not inserted or blocked by PIN, etc.).
Once the registration is complete, the antenna lights up steady together with any
bars indicating the signal strength.
On PAG08 of the SETUP menu you can see the quality of GSM coverage in real
time; the values are updated every three seconds. This feature is useful for testing
during installation if the position assumed is appropriate or not.
The following table shows the signal values and the corresponding messages
shown on the display.
Example:GSM:18.0meansthatthesignalisgood(twobars)andthecommunication
has no errors.

NOTE: during the first seconds after the programmable thermostat is switched on,
any anomalies of the SIM are indicated by the appearance of the following error
messages:
ERR 310 = no SIM; verify that the SIM is inserted correctly and close the latch
of the SIM holder;
ERR 311 = SIM has PIN protection; remove the SIM and insert it into a phone
to remove the PIN protection function.
N.B.: Any other error codes that may appear must be noted to then contact the
technical support.

MAN
JOLLY
“JOLLY” TEMPORARY PROGRAM:
you can choose to maintain a certain temperature for
a given number of hours, after which it will return to
the previously active program.
“MAN” MANUAL PROGRAM:
the programmable thermostat maintains a fixed
temperature, specified from time to time, for
unlimited time, until another program is selected.
“OFF/ANTI-FREEZE” SYSTEM IS OFF OR WITH
ANTI-FREEZE PROGRAM:
the system remains off or alternatively it will
maintainaverylowtemperature(2to7°C),toprevent
the liquid in the heating system from freezing.
PROGRAMMABLE TEMPERATURES
The operating temperature settings can be accessed in the AUTO and HOLIDAY
programs.
Temperatures T1, T2 and T3 can be represented with values ranging from 2°
to 40°C,
The T anti-freeze (TA) temperature can range from 2° to 7°C or be set to OFF
(that is, system off).
These are the temperatures that can be set when configuring the daily program:
The MANUAL program has its own specific temperature (TMan), just like the
JOLLY (Tj) program, which are set on the respective screens and that range

OFF
The OFF mode is used when you want to switch the system off.
It uses the TA temperature (anti-freeze) as a reference, to guarantee the
protection of the system at low temperatures.
TA is normally set to +5 degrees but can be set to OFF, obtaining therefore the
total shutdown of the boiler. Weekly or daily programs remain unchanged.
PROGRAMMABLE TEMPERATURES
The system requires 4 different temperature levels, three for normal use and one,
called "anti-freeze", to be used when you want to keep the boiler off but without
running the risk of the system liquid freezing.
The programming of the three T depends on the reciprocal values, in the sense that
T1 cannot be higher than T2, T2 cannot be higher than T3 or lower than T1 and T3
cannot be lower than T2.
You must therefore pay attention to their programming, which is achieved with the
TEMP key.
T1 varies between +2.0 and +T2 degrees, with changes every tenth of a degree [default 17.0]
T2 varies between +T1 and +T3 degrees, with changes every tenth of a degree [default 19.0]
T3 varies between +T2 and +40.0 degrees, with changes every tenth of a degree [default 20.0]
TA (anti-freeze) varies between +2.0 and +7.0 degrees, with changes every tenth of a degree,
or it can be OFF, that is, the boiler always remains off. [default 5.0].
