Iride Chronothermostat User Manual
Regulation parameters
In case of on/off regulation the only parameter to set is the hysteresis (
dIF
), which
can have values between 0.1°C e 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 36.
But remember that the preset settings are suitable for the most part of the
situations: to change these settings only if it’s really necessary.
Antifreeze temperature
(only for heating mode)
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 pressing the key
until the display
shows “
_-
.
-
” .
In this case, when the chronothermostat is
switched off, no safety temperature is maintained.
Password for key lock
It’s possible to set a key lock if the chronothermostat
is installed in public places or however if you want
to prevent anyone from modifying the operation
parameters.
To set a password, enter on field
PAs
a value
between 001 and 999. To deactivate the password
press the key
until “
__
.
_
” appears.
When the keyboard is locked, the chronothermostat performs all its functions using the
set regulation parameters.
