Ab
=
absolute temperature
: High and low ceiling
temperature alarms are established by the AL1 and
AU1 parameters.
AL1 Low temperature alarm for the ceiling
AC1
=
rE
: 0 ÷ 120°C
AC1
=
Ab
: Down scale ÷ Au1
when this temperature is reached and after the
dA1
delay time, the LA alarm is enabled,.
AU1 High temperature alarm for the bottom:
AC1= rE
: 0
120°C
AC1= Ab:
AL1
End Scale
when this temperature is reached and after the
dA1
delay time the HA alarm is enabled.
dA1 Temperature alarm delay for the ceiling
temperature:
(0÷120 min) time interval between the
detection of a ceiling temperature alarm condition
and the corresponding alarm signalling.
HA1 Differential for temperature alarm returns:
(1÷15°C) differential for the re-entry of the alarm
signalling.
AC2 Bottom temperature alarm configuration
rE
=
related to bottom Set Point
High and Low
temperature alarms are signalled when the
temperature exceeds the following values:
“SET+AU2” and “SET+AL2”.
Ab
=
absolute temperature
: High and low ceiling
temperature alarms are established by the AL2 and
AU2 parameters.
AL2 Low temperature alarm for the bottom
AC2
=
rE
: 0 ÷ 120°C
AC2
=
Ab
: Down scale ÷ Au2
when this temperature is reached and after the

delay time the HA alarm is enabled.
dA2 Temperature alarm delay for the bottom
temperature:
(0÷120 min) time interval between the
detection of a bottom temperature alarm condition
and the corresponding alarm signalling.
HA2 Temperature alarm differential:
(1÷15°C)
differential for the re-entry of the alarm signalling.
tcE Energy Saving cycle time (
1 ÷ 999 sec) it sets the
Energy Saving cycle duration.
dcy Switching on percentage for the ceiling output
during the Energy Saving cycle
(0 ÷ 100 %)
i1P Digital input polarity to enabling steam injection
(only for XF331M)
(oP÷CL)
oP =
the steam injection
is enabled if voltage is not present;
CL =
the steam
injection is enabled if voltage is present;
Ptb Parameter table code:
(read only) it shows the
original code of the map.
rEL Release software:
(read only) Software version of
the microprocessor.

Use of the programming key “Hot
Key”
The XF units can UPLOAD or DOWNLOAD the parameter
list from its own E2 internal memory to the
“Hot Key”
and
vice-versa.
14.1
DOWNLOAD (From the “Hot Key” to the
instrument)
1.
Turn OFF the instrument by means of the ON/OFF
key, insert the
“Hot Key”
and then turn the
instrument ON.
2.
Automatically the parameter list of the
“Hot Key”
is
downloaded into the controller memory, the “
doL
”
message is blinking. After 10 seconds the
instrument will restart working with the new
parameters.
At the end of the data transfer phase the instrument
displays the following messages:
“
End
“ for right programming. The instrument starts
regularly with the new programming.
“
Err
” for failed programming. In this case turn the unit off
and then on if you want to restart the download again or
remove the “
Hot key
” to abort the operation.
14.2
UPLOAD (From the instrument to the “Hot
key”)
1.
When the unit is ON, insert the “
Hot key
”
2.
Push the
UP
key of the Ceiling display; the
"uPL"
message appears.
At the end of the data transfer phase the instrument
displays the following messages:
“
End
“ for right programming.
“
Err
” for failed programming. In this case push “
UP
” key if
you want to restart the programming again or remove the
not programmed “
Hot key
”.
15.
Mounting & installation
The instruments are suitable only for internal use. They
are panel mounted, hole dims 69x135 mm, and fixed with
the supplied clips.
The ambient operating temperature range is between
0÷60°C.
Avoid locations subject to heavy vibration, corrosive gases
or excessive dirt. The same applies to the probes. Ensure
ventilation around the instrument.
