ASSEMBLY
• It is advisable to place the programmable
thermostat 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 programmable thermostat 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

keys, it is possible to move from
one hour to the next without modifying
the set temperature.
Pressing the
“ ” key, it is possible
to set the activation delay for that
specific hour. Each pressure of the
“ ” key increases the delay by 15
minutes.
Pressing the
“ ” key confirms
the modified program and returns to

MANUAL OPERATION
• During automatic operation, when pressing the “ ” key, the system will act as a
normal thermostat with operating temperature Tm.
Field
(22) will show the current time.
Field
(14) will show the current date.
Field
(15) will display the writing “ SEt ” .
The symbol
(18) will appear.
Field

SUMMER / WINTER OPERATION
To move from winter to summer operation
(or vice versa), press the “
” key with
a point (12).
On field (22) the writing “ rISC
”
(or “ Cond
” ) will flash and the symbol
“ ” (or “ ” ) will appear.
With the
“ ” and “ ” keys, it
is possible to select one of the two
operations.
The program will go to the desired
operation pressing the
“ ” key or after
45 seconds from the last operation.
The potential of the summer operation
is the same as the one of the winter
operation; therefore the setting of
all parameters can be carried out
following the procedures reported in this
instructions manual.

English

Mithos GSM Programmable Thermostat User Manual
• To deactivate the programmable
thermostat press the
“ ” key.
The display will show the
“ ” symbol.
Once deactivated, during winter
operation the programmable thermostat
will activate the antifreeze function to
ensure that the temperature does not
decrease below a certain threshold.
Such temperature value is set in
advanced programming (see "Antifreeze
temperature" page 20)
During summer operation, instead, the
deactivated system condition completely
excludes the refrigeration command.
To go back to the operating mode prior to the deactivation, press the
“ ” key
again.
KEYPAD ON-OFF COMMAND
TIMING
The programmable thermostat allows to activate three different timed operation
modes, useful when you want to maintain a certain condition for some hours/days.
The three timed operations are:
Manual operation
If in manual status you set a timing, such manual status will be maintained until
the end of the timing; operation will then switch to automatic. If, during the timing,
operation is switched to automatic or off, the timing ends.
Automatic operation
If in automatic status you set a timing, such automatic status will be maintained until
the end of the timing; operation will then switch to automatic. If, during the timing,
operation is switched to manual or off, the timing ends.

English
- 17 -
Mithos GSM Programmable Thermostat User Manual
To activate timing it is necessary to press
the
“ ” key
The writing “ 00h ”
will flash, indicating the
timing. With the
“ ” and “ ” keys it
is possible to choose a value between 0 and
99. Pressing the “
” key will allow to
choose the measurement unit between hours
and days.
Timed deactivation
If in off status you set a timing, such off status will be maintained until the end of
the timing; operation will then switch to the one active before deactivation. If, during
timing, the system is activated, the timing ends.
In all cases, the timing condition is signalled by the symbol “
” .
Setting a timing
Each change in measurement unit implies a
resetting of the set timing value.
Once the value has been set, press
“ ” to
confirm or wait 45 seconds.
Note. In case time is modified during timing, it will not be updated.
Note. In the hour count, the hour in which programming is carried out is
included. In the same way, if the measurement unit is in days, the count
also includes the current one. Timing in hours terminate on the hour,
the ones in days at midnight.
