ASSEMBLY
• It is advisable to place the chronothermostat
in an area that mirrors, as much as possible,
the conditions of average temperature of
the entire environment. Avoid installing too
close to doors, windows, heat sources, direct
sunlight radiation and positions with excess
or total lack of air inlet.
It is moreover advised to install the
environment chronothermostat at about
150 cm from the floor and in an area in wich
the GSM signal is good.
Assembly can be wall or box 503 coverage

SAFETY WARNINGS
■Mithos GSM RF is an electronic wall-mounting chronothermostat with GSM
module to be controlled remotely by sending an SMS or by using a suitable APP and
radiofrequency module to control the heating (or air-conditioning) system by sending a
radiofrequency signal to a remote actuator of Vemer range. The radiofrequency module
is used to associate the Mithos GSM RF up to 7 auxiliary actuators, which can be turned
on/off remotely with a simple SMS message. Mithos RF GSM executes actions of 1B
type and suitable for environments with a pollution degree 2 and overvoltage category III
(EN 60730-1).

INITIAL START-UP / RESET
Mithos GSM RF is a chronothermostat thought to be controlled remotely via SMS or
APP. To make this possible, it is necessary to have a SIM card of a telephone operator
to ensure a good coverage of GSM signal receiving.
1. Connecting the Mithos GSM RF to the GSM network
Mithos GSM RF is able to determine which operator ensures the best GSM coverage in
the area of installation.
Testing the GSM signal intensity
1. Turn on the Mithos GSM RF and make sure that no SIM card is inserted in the
housing
2. Press the “R” key and right after the “ ” key
3. The display shows “FLD” and then a screen like this:
Identifying operator Operator name
01 – 43 – 48 TIM
10 – 06 VODAFONE
88 – 44 WIND
99 – 33 3
4. Press the “ ” and “ ” keys to
scroll and check the intensity of the
signals of all detected operators.
5. To exit, press the “R” key
It is advisable to choose a SIM card of the
operator with the highest signal intensity.
Requirements of the SIM card
– It must be enabled to telephone traffic (voice, not SIM data)
– it must have the PIN code request disabled (if necessary use a mobile phone to
disable the request)
– it must have the voice mail disabled

Mithos GSM RF Chronothermostat User Manual
Insert the SIM card into the housing in the
underside of the Mithos GSM RF, with the rounded
edge facing inwards and to the right, the housing is
of push-push type (push to insert the SIM card and
press to remove it).
The status of the connection to the GSM network is
symbolized by the icon on the display:
– lit fixed: connected to the GSM network
– lit blinking: SIM card not inserted, GSM network
coverage lack / GSM network search
2. Connecting the Mithos GSM RF to the heating system
Mithos GSM RF can control the heating / air conditioning system in two ways:
- via relay
- via radiofrequency (RF) signal to be sent to a remote actuato
Connection to the system via relay
Connect the relay output respecting the diagram on page 5.
Caution: before making connections, be sure to disconnect the power supply
Connection to the system via radiofrequency (RF)
The connection to the system via radiofrequency assumes to have a remote actuator
of Vemer range to be associated with Mithos RF GSM.
The activation of heating / air conditioning occurs via the remote actuator controlled
by the Mithos GSM RF by means of a radiofrequency signal.
• To choose how to control the system, see page 27
3. Connecting the Mithos GSM RF to other actuators
Mithos GSM RF enables allows you to control via radiofrequency up to 7 independent
actuators.
This, coupled with the fact that the Mithos GSM RF can be controlled remotely via
GSM, implies that it is possible to control remotely up to 7 independent devices.
To do this you need to configure the connection between Mithos GSM RF and
actuators.
• To choose how to control the system, see page 27

Mithos GSM RF Chronothermostat User Manual
4. Auxiliary input connection
The chronothermostat allows you to connect a remote external temperature probe
for the displaying (and possibly also regulation) of the temperature measured where
the probe is placed or a not in live contact in case you want to connect an auxiliary
external device (for example a gas detector, an anti-theft system, a block boiler
detection system, ...).
In this last case, a possible change of the input status can be signaled by sending
an SMS to a specified number (for more info, see “GSM INTERFACE” on page 36).
• To configure the auxiliary external input, see page 26
