WARNING
When the regulation modes ‘d-EF’, ‘d-EC’ o ‘d-FP‘ are shown, the
calculated dew-point (dP) value will be alternately shown.
Dew point control limitations
- When the dew point control is active in modes ‘
d-EF
‘ or ‘
d-EC
‘,
the parameter ‘
rEG
‘ (room temperature regulation sensor) will be
automatically set to the internal sensor. The dew point temperature
will be calculated according to the temperature measured by the
internal sensor, meanwhile the ceiling or floor temperatures will be
calculated based on the remote sensor.
- When the dew point regulation is active in mode ‘
d-FP
‘ the
regulation sensor will be the internal one, meanwhile the external
sensor will only be used for the measured temperature.
- The dew-point temperature will always be calculated according
to the temperature measured by the internal sensor. Once the
parameter ‘
rEG
‘ is reached, the label ‘
indP
‘ will be shown on the
display, together with the ‘
SET%RH
‘ icon flashing. If the regulation
sensor has to be modified, the settings for the dew-point control
must first be modified.
- The dew-point regulation is active only when the regulator is set on
cooling and dehumidification. Otherwise the access to parameter ‘
C-dP
‘
will not be allowed and the label ‘
nOdP
‘ will be shown instead.
- The dew-point measurement is taken on a regular basis, according
to the value set in the parameter ‘
cndP
‘, from 3 minutes up to a
maximum of 27 minutes.
- When the dew-point regulation is activated either when restarting
from the states OFF, housekeeping or vacations, or when
parameters ‘
d-EF
‘, ‘
d-EC
‘ or ‘
d-FP
‘ have been changed; in this case
the regulator will restart for 1 minute with all relays in NC position,
in order to avoid sudden activations. After this phase the normal
regulation will be activated.
For further details regarding the parameters involved in the control of
the dew point, see the following paragraphs.
d-EF
’ Dew point control with external probe on underfloor
plants.
When the dew point regulation is active with the ‘C-dP’ parameter
set on ‘
d-EF
’, the regulator will control both systems attached for the
cooling and de-humidification according to the comparison between
the dew-point temperature and the temperature measured by the
external sensor, thus applying the settings of the regulation ‘
d-EF
’
regulation.

‘
d-FP
’ dew point control on fixed points
If the dew point control function, ‘
C-dP
’, is activated on ‘
d-FP
’, the programmable thermo-hygrostat controls the cooling and
dehumidification devices on the basis of the comparison of the
temperature value of the dew point calculated and the temperature
values relative to the dew points set in the sub-parameters ‘
TF1
’
and ‘
TF2
’.

On identification of the dew point temperature (table 1) which is to be
respected, thresholds ‘
TF1
’ and ‘
TF2
’ will be set in order to obtain
system adjustment such to prevent the formation of condensate.
Example:
dP >
TF1 = the dehumidification system starts to operate,
maintaining the cooling system active if it has already
been activated.
The following situation then occurs:
dP > TF2 = the dehumidification system remains active, but the
cooling system is deactivated.
Once the value of ‘
TF2
’ is set lower than the minimum temperature
of the cooling surface, this control allows to prevent the formation of
condensate on the surface for any temperature and relative humidity
value of the air.
ATTENTION
- The maximum value of ‘ TF1 ’ will be self-limited to ‘ TF2 ’ less
0.2°C.
- The ‘ TF2 ’ value must always be set with a value lower than
the minimum temperature reached by the cooling surface to
control or however than the coolest surface present in the
room.
to activate the Vacation Program, which will suspend the active
operating mode for the desired number of hours (from 1 to 95) or
days (from 1 to 99).
At the end of the set number of hours or days, the programmable
thermo-hygrostat will go back into the operating mode it was in prior
to activation of the Vacation Program. While it is off, and in case the
device has been set to Heating mode, the antifrost function will be in
any case active, and the display will show the symbol ‘ ‘ and the
countdown of the time remaining to the end of the program.
Note: Access to the vacation program will NOT be enabled while the
‘ cleaning program ‘ is on.
To activate the vacation program proceed as follows:
1.
Select the parameter ’
HOL
’ and press ’
OK
’; the display shows the
symbol ‘ ‘, the indication ’h 00’ and the ‘
P
‘ icon flashing.
2.
Press buttons ‘ ‘ and ‘ ‘ to set the vacation time;
every
change will be automatically memorized
.
Up to 95 hours, the programming is indicated in hours and the
display will show ‘ h XX ‘.
Once that value is exceeded, the device will automatically switch to
the mode for programming the vacation time in days and display will
show ‘ d XX ‘. It will be possible to increase or decrease the hour
or day by one unit at a time, with values ranging from 1 .. 95 hours
and 4 .. 99 days.
3.
To activate the holiday program for a given time, press again the
‘
OK
’ button or wait 10 seconds without pressing any key; the
display showsthe ‘
’ icon flashing and the time remaining to the
end of the holiday period.
If you have not set the time duration of the holiday (h:00), you can
exit the adjustment and return to normal operation by pressing the
‘
OK
’ or ‘
‘ or by waiting 10 seconds without pressing any key.
4.
To deactivate the vacation function and resume normal operation,
press the button ‘ ‘.
‘
H-C
’ HEATING / COOLING SETTING
This setting is used to invert the operating logic of the thermostat
relay according to whether a heating or air conditioning unit is being
controlled.
ATTENTION:
- By modifying the relay operating logic, the setpoint values
will be automatically taken back to the default values for the
mode set.
- The programmable thermo-hygrostat leaves the factory set in
the heating mode.
To modify the operating logic, carry out the following procedure:
1.
Select the parameter ’
H-C
’ and press ’
OK
’; the display shows the
current adjustment mode and the ‘
P
‘ icon flashes.
2.
Press the buttons ‘ ’ and ‘ ’ to select the desired adjustment;
each change is automatically saved
.
3.
To return to the list of user parameters, press the ‘
OK
’ button.
4.
To exit the user parameter settings and resume normal operation,
press the ‘ ‘ button or wait 10 seconds without pressing any key.
During normal operation, if the heating mode is on, the ‘ ‘ icon will
remain lit, whereas if the cooling mode is on, the ‘ ‘ will remain
steadily lit.
‘
HYH
’ SETTING HYGROSTAT HYSTERESIS
Setting this parameter allows to define the hysteresis, in %RH, which
is applied to the programmable thermo-hygrostat to adjust the room
humidity (
2.0 default
).
To adjust the differential, perform the following operations:
1.
Select the ‘
HYH
’ parameter and press ‘
OK
’.
2.
The display will show the previously set value and the ‘
P
‘ icon
will flash.
3.
Press the ‘ ‘ and ‘ ‘ keys to modify the value (between
0.5%RH .. 10.0%RH);
every modification is memorised
automatically
.
4.
To return to the list of user parameters, press the ‘
OK
’ button.
5.
To exit the user parameter settings and resume normal operation,
press the ‘ ‘ button or wait 10 seconds without pressing any key.
‘
OFSH
’ INTERNAL HUMIDITY SENSOR OFFSET SETTING
With this parameter it is possible to correct the humidity reading of
the internal sensor by ±5%RH in order to correct any systematic
reading errors due to the positioning of the programmable thermo-
hygrostat in areas unsuitable for measuring the room humidity. The
device leaves the factory with the Offset set at 0.0%RH.
To adjust the Offset value for the internal sensor, carry out the
following steps:
1.
Select the ‘
OFS1
’ parameter and press ‘
OK
’.
2.
The display will show the previously set Offset value and the ‘
P
‘
icon will flash.
3.
Press the ‘ ‘ and ‘ ‘ keys to modify the value (between
-5.0%RH .. +5.0%RH);
every modification is memorised
automatically
.
4.
To return to the list of user parameters, press the ‘
OK
’ button.
