Dafne chronothermostat, user’s manual
Regulation parameters
In case of
on/off
regulation the only parameter to set is the differential (
dIF
), which
can have values between 0.1°C and 1°C.
In case of
proportional
regulation the parameters to set are the regulation band (
bnd
)
and the regulation period (
PEr
).
For further information about how to choose these values see the chapter
“Regulation type” on page 38.
But remember that the preset settings are suitable for the most part of the
situations: change these settings only if it’s really necessary.
Antifreeze temperature
(for heating mode only)
For the heating mode it’s possible to set a safety
temperature (antifreeze temperature –
0ff
) to
maintain also if the chronothermostat is switched
off.
It’s possible to choose a value between 1°C and
10°C. It’s also possible to deactivate the antifreeze
function by pressing the key
until the display
shows

.
In this case, if the chronothermostat is
switched off, no safety temperature is maintained.
Password for keylock
It’s possible to set a keylock if the chronothermostat
is installed in public places or if you want to prevent
anyone from modifying the operation parameters.
To set a password, enter on field

between 001 and 999. To deactivate the password
press the key
until

When the keyboard is locked, the chronothermostat
