thermal inertia and the various environmental conditions.
Generally, a minimum of 1°C is recommended for underfloor
plants and 3°C for metal ceilings.
‘CndP’ Rate of check for the dew-point regulation
This parameter allows to set the minimum time, in minutes, which
must elapse between two consecutive activations of the output
relays, caused by the ‘
c-dP
‘ function intervention.
This time interval can be set in steps of 3 minutes; itwill be re-
initialised every time the dew-point regulation mode is changed by the
user (‘
d-EF
’, ‘
d-EC
’ or ‘
d-FP
‘).
‘
Cntr
’ THERMOSTAT RELAY ACTIVATION TIMER
Using this parameter it is possible to display the thermostat
relay activation time meter relative to the actual day. The timer is
automatically reset at midnight.
Proceed as follows:
1.
Select the ‘
Cntr
’ parameter and press ‘
OK
’, the device displays
the hours of activation of the thermostat relay alternating with the
wording ‘
Cntr
’ + the ‘
P
‘ icon.
2.
To go back to the list of user parameters, press ‘
OK
’ and then the
‘ ‘ key.
3.
To exit user parameters setting and restore normal operation, press
‘ ‘ or do not press any key for 10 seconds.
‘
dFLt
’ SET DEFAULT DATA
With this parameterit ispossible to resetuser parametersin order
tobring back all theparameters to thefactory defaults.
Proceed as follows:
1.
Select the parameter ’
dFLt
’ and press ’
OK
’; the device
automatically sets the default data and the display will show ’
-dF-
’
and the ‘
P
‘ icon flashes.
2.
To return to the list of user parameters, press the ‘
OK
’ button.
3.
To exit the user parameter settings and resume normal operation,
press the ‘ ‘ button or wait 10 seconds without pressing any key.
WARNING!
Restoring the Default Data will reset all settings made by the
user, such as Time Program, Heating/Cooling, Set-Points and all
other programmable data.
SWITCHING OFF - ANTIFREEZE FUNCTION
To deactivate the programmable thermo-hygrostat press the ‘ ‘
button.
The display will show the word ‘
OFF
’.
If the programmable thermo-hygrostat has been set in the heating
mode, the Antifreeze function will be active and the ‘ ‘ symbol
will appear on the display; in such a case the room temperature will be
controlled based on the value set for the Antifreeze temperature (see
paragraph ‘SETTING THE USER PARAMETERS‘).
AUTOMATIC OPERATION / 24H MANUAL / PERMANENT
MANUAL OVERRIDE FUNCTION
With the ‘ ‘ key, the programmable thermo-hygrostat may be forced
to adjust the room temperature and humidity according to the comfort
temperature and humidity set, regardless of the time programming
settings.
By pressing the ‘ ‘, button repeatedly you can switch from
Automatic to 24 hour Manual, from 24 hour Manual to Permanent
Manual and from Permanent Manual back to Automatic.
During operation in manual mode, the display does not show the time
program, but only the room temperature, the status of the relays (any
switch-on of the ‘ ‘ or ‘ ‘ or ‘ ‘ symbols), the ‘
24h
‘ symbol
(manual 24h) or ‘ ‘ (permanent manual) and the ‘ ‘ symbol.
Pressing the ‘ ‘ button once will activate the 24 hour Manual mode
and the programmable thermo-hygrostat will remain in this mode
until the time 23:59 is reached, after which it will go back into the
Automatic mode.
Note: If the device is set in the 24h Manual mode and the Vacation
program is activated, after the Vacation period has elapsed, if it is
past the time 23.59, the programmable thermo-hygrostat will go back
into the Automatic mode and follow the set program schedule.
Pressing the ‘ ‘ button a second time will switch the programmable
thermo-hygrostat into the Permanent Manual mode and it will remain
in this mode until you press the ‘ ‘ button again.
TIME/TEMPERATURE/HUMIDITY DISPLAY
By repeatedly pressing the ‘
‘ button, the display can show the
actual time with the icon relative to the temperature adjustment probe
(internal ‘
‘ or external ‘
‘), the room temperature read by the
internal sensor, distinguished by the ‘ ‘ icon, the room temperature
read by the remote probe (if connected) distinguished by the ‘
‘
icon and the room humidity read by the internal sensor, distinguished
by the ‘ ‘ icon.
The temperature and humidity readings are displayed corrected by the
Offset value set.
Note: If the ‘
rEG
’ parameter is set at ‘
In
’, but an error is detected
on the internal sensor, the display will show ‘
SEnS E xx
’. In
this situation the adjustment will be automatically interrupted
and both relays will be placed in the Normally Open position.
If the ‘
rEG
’ parameter has been set at ‘
Out
‘ but the remote
probe has not been connected or is damaged, the display will
show the respective wording ‘
SEnS OPEN
‘ or ‘
SEnS SHrt
‘
with the ‘
‘ icon on.
ATTENTION:
- In order to optimise battery duration, the programmable
thermo-hygrostat reads the room temperature every 3 minutes
and, consequently, decides on activation or deactivation of the
relays.
- Press the ‘ OK ’ button briefly to perform an instant refresh.
BACKLIGHTING
The display backlight turns on whenever and button is pressed. It
turns off automatically 20 seconds after the last pressing of a button.
HOW TO INSERT / REPLACE BATTERIES
The battery charge status is constantly displayed by means of the
‘
‘ symbol.
The battery charge is at a maximum if all three level indicators are lit
inside the symbol. If the ‘
‘ symbol (completely empty) flashes,
it means that the batteries are depleted and must be replaced. In
this case, both the relays are placed in the safety position (N.C.) and
the display alternately shows the time (or temperature or humidity)
and the word ‘
BATT
’. If the batteries are not replaced as soon as
possible, the ‘ ‘ or ‘
‘ symbols will also flash indicating that
the device is blocked.
To replace the batteries proceed as follows:
1.
Open the flap of the battery compartment (Fig. 1).
2.
Remove the batteries, prying them out with the aid of a tool if
necessary.
3.
Insert the new batteries, which must be alkaline 1.5V type AA.
4.
Check for correct time and date and eventually reset it.
CONNECTION TO A TELEPHONE INTERFACE
The programmable thermostat allows to connect a telephone interface
with continuous operation (latching relay) to the connector ‘
B
‘ in
Fig. 6.
Use of a suitable telephone interface does not require any setting to be
made on the programmable thermo-hygrostat; for directions on using
the telephone interface see the instruction manual provided.
Via a telephone interface it is possible to turn the programmable
thermo-hygrostat Off or turn it On in the Permanent Manual mode.
Depending on the commands received from the telephone interface the
programmable thermo-hygrostat will act according to the following
operating logic:
1. Telephone interface contact closed:
The programmable thermo-hygrostat will switch into the
‘Permanent Manual’ mode: the ‘ ‘ and ‘ ‘ symbols will be
shown on the display.
2. Telephone interface contact open
, after (and only after) a
previous closure, if no buttons have been pressed (Manual/Off):
The programmable thermo-hygrostat will be switched off and the
word ‘OFF‘ will be displayed along with the ‘ ‘ symbol. If the
‘Antifreeze’ function is active the ‘ ‘ symbol will be displayed.
IMPORTANT: the commands input by pressing the control
buttons will always have priority over the commands received
from the telephone interface.
If you press the ‘ ‘ or ‘ ‘ button on the programmable thermo-
hygrostat, the device will change its status and the ‘ ‘ icon will
flash to indicate that the interface command has been overridden by a
command input with a control button.
The ‘
‘ icon will stop flashing if the telephone interface sends the
programmable thermo-hygrostat the same command as the one made
with the button or if the telephone interface is reset. In such a case
the status set by means of the control button will not be changed
and the programmable thermo-hygrostat will be ready to receive a
new command.
IMPORTANT
If an Off command is sent to the programmable thermo-
hygrostat via the telephone interface (contact open), it is a
good idea to check that the command has been executed by the
programmable thermo-hygrostat by carrying out the following
realignment procedure:
1. Using the functions of the telephone interface, check that the
contact is open, sending an Off command if necessary.
2. Send a command to the telephone interface to close the
contact (the programmable thermo-hygrostat will turn on).
3. Using the functions of the telephone interface, check that the
contact is closed.
4. Send a command to the telephone interface to open the
contact (the programmable thermo-hygrostat will turn off).
During this sequence no commands should be input with the
control buttons as they have priority over the interface commands.
