INSERTING AND REPLACING
THE BATTERIES
Insert two long life AA 1,5V alkaline batteries,
paying attention to the indicated polarity.
Batteries last approximately 2 years: when
they begin to run down, the battery symbol
starts to flash on the display.
If the batteries are not replaced within
15 days, Intellitherm C57 will switch-off
automatically and the display will indicate
OFF.

ELECTRIC CONNECTIONS
Connect terminals 1 - 2 to the heating system
with two wires thus replacing the traditional
thermostat at any time and without adding
further connections. When the ambient
temperature increases, the relay will open
terminals 1 - 2 and will close terminals 1-4.
Terminal 4 is free and it may be used for
signalling or other purposes, as required.

OFF MODE SELECTION
When in OFF mode, Intellitherm may be set
to keep a fixed temperature of 5°C to protect
the system from the risk of freezing.
This selection must be carried out during
the installation and before inserting the
batteries.
Note: if this selection is needed to be
changed after the installation, Intellitherm
has to be reset and reprogrammed.
To set the ANTIFREEZE 5°C protection
move the dip switch HIGH.
To switch the system completely OFF,
move the dip switch DOWN.
