5  DESCRIPTION OF THE APPLIANCE

5.1 

Characteristics

MIA-30

 are condensing wall mounted boilers which 

Sime Ltd

 

has produced for installation into domestic properties for 

heating and hot water production. The main design choices 

made by 

Sime Ltd

 for the 

MIA-30

 boilers are:

–  the total pre-mix microflame burner combined with a steel 

heat exchanger for heating and a rapid heat exchanger for 

DHW

–  room sealed, Type C appliance. Suitable for use on sealed 

heating systems

–  the microprocessor electronic control board, which makes 

the heating and domestic hot water production system 

easier to manage and offers the option to be connected to 

room thermostats or to a remote control (with Open Therm 

protocol) and also to an external sensor. Where connected 

to an external sensor, the boiler temperature varies on the 

basis of the external temperature, according to the selected 

optimal climatic curve. This provides significant energy and 

cost savings.

Other special features of the 

MIA-30

 boilers are:

–  the anti-freeze function which activates automatically if the 

temperature of the water inside the boiler falls below the 

threshold of the value set at parameter "tS 1.0" and , if there 

is an external sensor, if the external temperature falls be-

low the threshold of the value set at parameter "tS 1.1".

–  anti jamming function of the pump and diverter valve, this 

activates automatically every 24 hours if no request for heat 

has been made

–  the chimney sweep function lasts 15 minutes and makes 

the job of the qualified technician easier when measuring 

the parameters and combustion efficiency

–  screen display of the operating and self-diagnostic param-

eters with error code display when the fault occurs. This 

makes repair interventions easier and allows appliance op-

eration to be restored correctly.

5.2 

Check and safety devices

The 

MIA-30

 boilers are equipped with the following check and 

safety devices:

–  thermal safety thermostat 100°C

–  3 bar relief valve

–  heating water pressure switch

–  delivery sensor (SM)

–  DHW sensor (SS)

–  exhaust sensor (SF).

DO NOT

Do not commission or operate the appliance with 

safety devices which do not work or which have been 

tampered with.

WARNING

Safety device may only be replaced by professional 

qualified personnel using 

Sime Ltd

 original spare 

parts.

5.3 

Identification

The 

MIA-30

 boilers can be identified by means of:

1  Packaging label: 

this is located on the outside of the pack-

aging and provides a code, the serial number of the boiler 

and the bar code

2  Energy Efficiency Label: 

this is positioned on the outside of 

the packaging to notify the User of the level of energy sav-

ings and reduced environmental pollution produced by the 

appliance

3  Technical Data Plate: 

this is located on the side of the ap-

pliance and provides the technical data, appliance perfor-

mance and any other information required by law.

4  Steaker of product identification
