1 HOW TO USE THIS INSTRUCTION MANUAL
This manual is intended for:
▶ Installer: provides information on the correct installa-
tion and conguration of the remote control.
▶ User: provides detailed information on the steps to be
taken to customize the operation of the remote control.
Suggestions:
▶ When a numerical value is displayed ashing, you can
change it by turning the knob.
▶ The value modied by the knob must be saved by
pressing the knob before the timeout, otherwise
it will not be saved.
2 MAIN FEATURES
The remote control for Caldaria has been designed to en-
sure ideal temperature conditions at all times of the day,
allowing any remote boiler setting to be made.
The remote control can be programmed with extreme
ease: a large LCD display makes this operation easier, al-
lowing you to check the settings you have made and to
change them at any time.
The remote control is electrically connected to the boiler
by means of two non-polarized conductors through which
it receives the power supply necessary for its operation
and carries out communication between the two devices.
Once installed it is ready to work with its standard stored
program. The program can be modied according to the
user's needs.

3 INSTALLATION
For installation of the remote control
on the Caldaria Plus refer to the
Installation, use and maintenance manual sup-
plied with the Caldaria Plus.
The installation of the remote control must be car-
ried out by qualied personnel.
How to install the remote control
1. Disconnect the boiler power supply.
2. Using a screwdriver, slide the remote control interface
out of the rear xing box, applying slight pressure on
the two lower tabs (Figure 3.1 p.5 ).
3. Insert the two ends of the connection cable into
the slot in the xing box. Install the remote control,
through the holes provided, directly on the wall or on
a ush-mounting box, using the screws provided and
taking care to follow the instructions " UP" (Figure
3.2 p.6 ).
It is recommended to position the remote control
at about 1,5 m from the oor, away from draughts,
direct exposure to sunlight, inuence by direct
heating sources (lamps, hot air ows, etc..) and pos-
sibly on walls not bordering the outside, so as not
to distort the measured temperature and therefore
the operation of the system. In this way, unwanted
starts and stops of the system will be avoided and
optimal comfort in the environment will be guar-
anteed.

4. Perform electrical connection to the terminal block
(Figure 3.3 p.6 ).
The connection is not polarized.
Figure3.3Electrical connection of the remote control
5. Fix the remote control to the xing box by rst insert-
ing the upper part and pivoting on it until it is com-
pletely closed (Figure 3.4 p.6 ).
Figure3.4Closing the remote control
6. Connect the other end of the connection cable to the
boiler, removing any electrical bridge on the room
thermostat terminals.
Refer to the boiler Manual for further information
and diagrams.
7. Power the boiler.
8. The installation is now complete. If the remote control
has been correctly installed, it will be powered up and
the connection message will appear on the LCD dis-
play for a few seconds (Figure 3.5 p.6 ).
Figure3.5Remote control connected
9. Once the connection has been established, the nor-
mal operating condition will be presented (Figure
3.6 p.6 ).

4 CONFIGURATION OF THE OPERATING PARAMETERS
This Paragraph is reserved exclusively for the
authorised Robur Technical Assistance Centre.
Incorrect conguration of the remote control may
cause the system to malfunction.
This operation is used to congure the remote control in
such a way that it is compatible with the boiler and the
relative system to which it is connected.
How to congure the operating parameters
1. Set the remote control to OFF mode (Paragraph
7 p.9 ).
2. Press and hold down the and
keys until PAr appears on the display.

Installation and operation manual – remote control 7
3. To conrm access, press the key. The display
shows the parameter number instead of the time and
the value associated with the parameter instead of the
temperature. The parameter number ashes (Figure
4.1 p.7 ).
Figure4.1Selection of the parameter to be modied
4. Turn the knob to select the parameter number
to be displayed. The display shows the value of the
parameter.
5. To change the value press the knob: the value
associated with the parameter starts ashing (Figure
4.2 p.7 ).
6. Turn the knob to change the displayed value.
If no key is pressed for a period of 30 seconds, the
change made is aborted and normal operation is
restored.
7. Press the knob to save the value.
8. To exit the conguration mode, press .
Figure4.2Changing the selected value (ashing)
The editable parameters are as follows:
▶ P00 Room temperature probe correction
Value to add/subtract (-5.0 °C ÷ +5.0 °C) to the dis-
played room temperature to compensate for any
errors.
▶ P01 Trip temperature for the room antifreeze function
Trip temperature for the room antifreeze function
(0,1 ÷ 10,0 °C).
Setting parameter P01 to 0,0 disables the room an-
tifreeze function.
▶ P02 Thermal dierential (OFF)
Value to be added to the set room setpoint that de-
termines the end of the heating request.
Example:
Tsetpoint = 20,0 °C
P02 = 0,5 °C
Tsetpoint + P02 = 20,0 + 0.5 = 20,5 °C
The heat demand ends when the Troom is greater
than 20,5 °C.
▶ P03 Thermal dierential (ON)
Value to be subtracted from the set room setpoint
that determines the start of the heating request.
Example:
Tsetpoint = 20,0 °C
P03 = 0,5 °C
Tsetpoint - P03 = 20,0 - 0,5 = 19,5 °C
The heat demand starts when the Troom is less than
19,5 °C.
▶ P04 Thermoregulation type
0 = On / O
1 = Modulating on room temperature probe
2 = Modulating on outdoor temperature probe
3 = Modulating on outdoor and room temperature
probes
4 = Disabled
▶ P05 BUILD parameter of the fan heater control board
Compensation coecient, in relation to the type of
building, of the automatic control algorithm of the
35 kW PLUS fan heater control board.
The parameter only has eect for Caldaria 35 Tech
PLUS.

P04 Thermoregulation type 0 ÷ 4 0
P05 BUILD parameter of the fan heater control board 0 ÷ 30 30
5 DISABLING THERMOREGULATION
If the remote control is installed in an environment where
the temperature is not to be controlled (technical room,
oce, other room than the boiler heated one), it is possi-
ble to disable the request for heat from the remote control
itself. To do this, set parameter P04 = 4 (see Paragraph
4 p. 6 ). Instead of the room temperature, the display
shows dIS (Figure 5.1 p.8 ).
Figure5.1Room temperature control from remote control:

6 CONFIGURATION OF BOILER-RELATED PARAMETERS
(TRANSPARENT PARAMETERS - TSP)
This Paragraph is reserved exclusively for the
authorised Robur Technical Assistance Centre.
The remote control does not know the meaning of the
items it displays but simply acts as a graphical interface to
the boiler board.
The number of parameters to be set is transmitted via
OpenTherm protocol.
How to congure transparent parameters (TSP)
1. Set the remote control to OFF mode (Paragraph
7 p.9 ).
2. Press and hold down the and
keys for longer than 10 seconds. The display will show
the ashing word tSP.
3. Release the and keys and, to
enable the conguration, press the knob within
10 seconds.
4. The display shows the ashing number of the
parameter instead of the time and the value associat-
ed with the parameter instead of the temperature.
5. Turn the knob to select the parameter number
to be displayed. The temperature display shows the
values associated with the various parameters. Once
the desired parameter has been selected, press the
knob again: the parameter number stops ash-
ing and the value associated with the parameter starts
ashing to indicate that the value can be changed.
6. Turn the knob to change the displayed value. To
save the value, press the knob again.
If no key is pressed for a period of 10 seconds, the
change made is aborted and normal operation is
restored.
7. To exit the conguration mode before the timer ex-
pires, press the key.

7 OPERATION MODE SELECTION
Depending on the boiler to which it is connected,
some of the operating modes described may not
be available.
The operating mode of the boiler is selected by press-
ing the key several times. The available operating
modes are those shown in Table 7.1 p.9 .
In all modes except OFF the boiler will produce hot water
at the set temperature, modulating the heat output as the
setpoint temperature is approached.
Regardless of the selection made, the room antifreeze
function is always active (Paragraph 15 p.17 ).
