Some hints
• When a numeric value is blinking you can
change it by turning button .
• The value as changed by turning button
will be automatically stored when the
blinking stops.

MAIN FEATURES
e CRD PLUS remote control device has
been designed to guarantee ideal temperature
conditions at any moment of the day oering
the possibility to set the boiler from remote.
e programming of the CRD PLUS remote
control device is extremely easy a large LCD-
display makes it possible to check and change
the set values at any time.
The CRD PLUS remote control device is
electrically connected to the boiler by means
of two nonpolarized conductors.
ey give it the necessary supply
to operate and constitute also the communi-
cation between the two devices.
Aer installing it is immediately ready to run
with its memorized standard program.
is program can be changed according to the
needs of the user.
1. INSTALLATION
e CRD PLUS remote control device must be
installed only by expert personnel.
To correctly install the device and in com-
pliance
with the regulations in force about electrical
appliances, use a dedicated line to connect it.
In case this is impossible, any interferencedue
to electric wires may cause poor working of the
remote control device.
Install the CRD PLUS remote control device
at approx. 1.5 m over oor in a place suitable
for correct sensing of the room temperature.
Do not install behind doors, curtains, near
heat sources nor expose to direct sunlight or
water sprinkles.

1. Cut o electricity from boiler
2. Use a screwdriver and gently press on the
two lower splines to take o the device from
the back of its xing template.
3. Insert both ends of the connecting wire into
their proper seat on the xing template. Use
the proper holes to install the CRD PLUS
remote control device directly onto the wall
or onto a housing. e necessary screws
are supplied together with the device. Pay
attention to the sign “ U P ”.

3. CONFIGURATING
OPERATING PARAMETERS
is operation must be done by technical
service personnel only.
Errors in the configuation of your CRD
PLUS remote control device may lead to
malfunctioning.
is operation congures the remote control
device to be compatible with the boiler and
the system to which it is connected.
1. Move the remote control device to OFF
position.
2. Press the keys and fand
keep them pressed until the display will
show PAr.
3. To conrm the function press button .

13
4. Turn button pto select the parameter
number to be displayed. e temperature
display will show the corresponding para-
meter value.
5. Press button : to change this value. e
corresponding parameter value will start
blinking.
6. Turn button to change the displayed
value.
7. If within 30 sec. no key is pressed, normal
operation will be restored and the last
change made will not be saved.
8. Press button to store the value.
9. To change the parameter repeat from
point 4.
10. To exit the conguration context press
key .

Hereaer you can nd the denition of para-
meters you can change:
• P00 - Room temperature sensor compen-
sation (Default 0°C)
It is the value (-5.0°C ÷ +5.0°C) to be added to/
detracted from the displayed room temperatu-
re in order to compensate any possible error.
• P01 - Room anti-frost Start temperature
Range (Default 5.0°C)
It denes the start temperature for the room
anti frost function (0.1°C ÷ 10°C).
N.B.: 0.0 = value 0.0 disables the room anti
frost function.
• P02 - Dierential operation temperature
OFF (Default 0.3°C)
It is the value to be added to the room setpoint
in order to dene the end of the
Central Heating Demand.
Example:
Tset point = 20.0 °C
P02 = 0.5 °C
Tset point + P02 = 20.0 + 0.5 = 20.5 °C
e central heating demand ends whenever
the room temperature is higher then 20.5°C.
• P03 - Dierential operation temperature
ON (Default -0.1°C)
It is the value to be subtracted from the room
setpoint in order to dene the start of the
Central Heating Demand.
Example:
Tset point = 20.0 °C
P03 = 0.5 °C
Tset point - P03 = 20.0 - 0.5 = 19.5 °C
e central heating demand starts whenever
the room temperature is lower then 19.5°C.
• P04 - ermo-regulation type (Default 0)
0 = ON/OFF

15
1 = Modulating on Room Temperature sensor
2 = Modulating on External Temperature Sen-
sor (Outside Temperature Compensation)
3 = Modulating on Room and External Tem-
perature sensors
4 = Disabled
4. DISABLING
THERMOREGULATION
In case the remote controller is installed inside
a generic environment and you do not need
to control its temperature, you can disable
the Central Heating demand request trough
proper configuration of parameter P04 =
4 (see chapter 5 - Congurating operating
parameters).
With this kind of conguration the word diS
is displayed on the remote controller LCD
screen in place of the room temperature.; in
this condition, heating requests will never
be activated. It is therefore necessary for the
boiler to have an additional input in order to
manage the heating request.
