GENERAL SAFETY INFORMATION
PRECAUTIONS
a Always turn the electrical power supply OFF at the main
switch before commencing any cleaning or maintenance.
a Do not tamper with or adjust the safety or control devices
without prior authorisation and instructions from the boi-
ler’s manufacturer.
a Never pull, disconnect, or twist the electrical cables
coming from the appliance even if it is disconnected from
the mains electricity supply.
a Dispose of packaging materials in compliance with appli-
cable standards and legislation governing the disposal of
urban, domestic and industrial waste.
a Never switch the control panel on even for a short period
if the safety devices are not functioning correctly or have
been tampered with.
a All maintenance and repairs must be carried out by a
legally qualified heating engineer.
a Do not use water to extinguish fire in the control panel.
Switch power OFF at the mains power switch to isolate
the control panel electrically first. Then use a class E fire

RIELLOtech PRIME control panels are thermostatic con-
trol panels for use with dedicated central heating boilers
equipped with single stage jet burners.
All thermostatic control devices comply with applicable
technical and safety standards, and are housed in an
ABS box.
All the electrical control and safety devices in RIELLOtech
PRIME control panels are factory tested in compliance
with applicable technical standards. Control panels may
be installed on top of the boiler or on one of its side
panels, using the optional side panel mounting kit.

RIELLOtech PRIME control panels can be installed either on the top of the boiler or on one of its side panels. Before
commencing installation, check the arrangement of the holes on the top panel or side panel of the boiler.
Once you have identified the right holes for the type of installation required, proceed as follows:
- Push out the pre-formed slots on the boiler casing corresponding to the oval cable grommets in the control panel
- Perforate the membranes of the control panel cable grommets. Pull out the thermostat cable and route it through the
slot in the top panel
- Secure the control panel to the boiler casing.

ACCESSING INTERNAL COMPONENTS

12
b The following instructions are mandatory:
1 - Use a single pole magnetic thermal trip switch
and disconnector conforming to IEC-EN stan-
dards (with a contact gap of at least 3 mm);
2 - Respect the L (Phase) - N (Neutral) polarity.
Keep the ground wire about 2 cm longer than the
power wires.
3 - Use cables with a cross section of 1.5 mm2or
more, complete with end terminals;
4 -
Always refer to the electrical wiring diagrams in
this manual when performing any electrical work.
5 -Make sure the appliance is connected to an
effective ground.
- Proceed as instructed in the “ACCESSING INTERNAL
COMPONENTS” section above to access the terminals
inside the control panel.
- Route the connection cables through the cable grom-
mets in the casing of the boiler or secured by the side
mounting bracket. Alternatively, use the holes provided
for cable glands or spiral sleeving. To use these holes,
push out the pre-formed hole covers in the correspon-
ding positions on the control panel.
- See the “WIRING DIAGRAMS” section for information
on how to connect up the individual devices.
- Tighten the screws on the cable clamps and screw up
the cable glands to secure the cables against pulling.
Secure the cables to the casing of the boiler as neces-
sary.
b Use the terminals provided to connect all 230 V
power users to ground.
a It is strictly forbidden to use gas and/or water pipes
to ground the appliance.
a Do not route the power cable or room thermostat
cables near hot surfaces (like heating circuit flow
pipes). Use a suitable class of cable if there is any
possibility of contact with parts at temperatures
above 50°C.
The manufacturer declines all responsibility for dama-
ge caused by failing to ground the appliance adequa-
tely or by failure to respect the wiring diagrams pro-
vided in this manual.
All electrical connections must be made by a legally qualified heating engineer according to the following instructions.
(In Italy heating engineers are regulated by law 37 of the 22/01/2008.)

DESCRIPTION OF FUNCTIONS
Main control panel ON/OFF switch (b)
This switch connects power to all controlled devices and
appliances.
b A delayed action 6.3 A fuse is installed inside the control
panel upstream from this switch (see wiring diagram).
Control thermostat ( r )
The control thermostat lets you adjust boiler temperatu-
re between 60 and 82°C The recommended setting is
around 70°C.
Safety thermostat (TS)
The safety thermostat shuts down the burner if boiler
temperature exceeds 110°C.
To restore normal functioning, remove the protective
cover and press the button . Use a suitable tool if
necessary.
b If the safety thermostat (TS) shuts down the burner,
the red warning light comes on and any burner
error signals on the burner controller are lost.
Minimum temperature thermostat (Tm)
This thermostat prevents cold water from circulating and
causing condensation inside the boiler. It is located insi-
de the control panel, and is preset to 40°C. Adjustment
requires a suitable tool and is reserved for personnel from
r’s Technical Assistance Service.
RIELLOtech PRIME control panels are equipped with 3 homologated electromechanical thermostats, a temperature
gauge, a main power ON/OFF switch, function indicators and a protective fuse.
