First start-up may exclusively be carried out by a
Robur TAC (Chapter 5 p. 30).
Never power the appliance off while it is run-
ning
NEVER power the appliance off while it is running
(except in the event of danger, Chapter III.1 p. 4),
since the appliance or system might be damaged.
Routine switching on/off
The appliance may exclusively be switched on/off
by means of the suitably provided control device.
Do not switch on/off with the power supply
switch
Do not switch the appliance on/off with the power
supply switch. This may be harmful and dangerous
for the appliance and for the system.
6.2 PRELIMINARY CHECKS
Checks before switching on
Before switching on the appliance, ensue that:
„
Gas valve open.
„
Appliance electrical power supply (main switch
ON).
„
The fumes exhaust duct is free and correctly con-
nected to the fumes exhaust system.
„
The hydraulic circuit has been filled. If this is not the
case, fill the system according to the instructions in
Paragraph 3.2.4 p. 18 and 3.5.3 p. 25.
„
Check on the pressure gauge that the system pres-
sure is 1,5 bar.
If there is no water in the system or if the system
pressure is lower than the minimum required pres-
sure,
and error E73 appear on the display of
the control panel (Figure 6.2 p. 39), while error
E173 appears on the DDC panel (if any). When the
correct pressure is restored, the error code disap-
pears.
6.3 OPERATION WITH EXTERNAL
REQUEST
6.3.1
Turning the boiler on and off
6.3.1.1
Switching on
1. Open the gas tap and provide electrical power.
2. Supply the boiler with electric power by closing the
omnipolar switch (to be provided by the installer).
3. Press the
key on the control panel of the boil-
er (Figure 6.1
p. 39) and select the desired operating
mode.
4. The fixed symbol that appears on the display, corre-
sponding to the operating mode, indicates that the
function has been activated.
The burner is only ignited when there is a
heating service request from the provided con-
trol device (e.g. thermostat, timer, switch, con-
tactor ...).
After a long period of unit inactivity or at the first
start-up, it may be necessary to repeat the ignition
operation a few times due to the presence of air in
the gas piping.
6.3.1.2
Switching off
The burner switches off automatically when the heating
service request from the provided control device (e.g.
thermostat, timer, switch, contactor ...) is switched off or
when the setpoint is achieved.
To switch off the boiler, press the
button on the
boiler (Figure 6.1 p. 39) until the symbol appears on
the display.
6.3.2
Heating mode
In this operating mode the boiler provides heating only:
To switch the boiler to the space heating operating mode:
1. Press the
key (Figure 6.1 p. 39), the fixed
symbol will appear on the display, indicating that
the function has been activated.
2. Adjust the heating water temperature as described in
Paragraph 6.3.3 p. 40.
3. Whenever there is a request for space heating, the au-
tomatic ignition system will ignite the burner; the op-
eration is represented by the ignition of the
sym-
bol with an intermittent signal on the display.
6.3.3 Setting the heating temperature
The temperature is adjusted using the and keys of
the heating circuit (Figure 6.1 p. 39):
1. Pressing the
key decreases the temperature.
2. Pressing the
key increases the temperature.
3. The heating temperature control range is from a mini-
mum of 30 °C to a maximum of 80 °C.
In order to change the heating temperature con-
trol range, parameters P69 (minimum heating set-
point) and P70 (maximum heating setpoint) must
be changed, Paragraph 5.3
p. 31.
6.3.4 OFF mode
In this operating mode the boiler no longer provides heat-
ing and DHW, but the antifreeze and pump anti-lock sys-
tems remain active.
To switch the boiler to the OFF operating mode, press
the
key; the fixed symbol will appear on the
