Auto button - Temperature adjustment activation

The  AUTO  function  enables  boiler  operation  to  be  adapted  to 

external environmental conditions and to the type of system it is 

installed in. 

Comfortable temperature is reached inside the room in the quickest 

way possible, without wasting money, energy or efficiency, while 

substantially  reducing  the  amount  of  wear  experienced  by  the 

components.

Contact  one  of  our  qualified  technicians,  who  will  advise 

you  on  the  devices  connectable  to  the  boiler  and  will 

program it according to the system.

In  normal  boilers  the  water  temperature  inside  the  heating 

elements is usually set to a high value (70-80°C), thereby ensuring 

effective  heating  during  the  few  really  cold  winter  days.  It  then 

becomes  excessive  on  less  cold  days  (of  which  there  are  many) 

more typical of the autumn and winter seasons. This habit leads 

to excessive room heating after the thermostat has been switched 

off, resulting in energy waste and uncomfortable conditions inside 

the room.

The  new  AUTO  function “takes  control”  of  the  boiler  and  selects 

the  best  operating  regime  based  on  environmental  conditions, 

external  devices  connected  to  the  boiler  and  the  performance 

required.  It  constantly  decides  at  which  power  level  to  operate 

based on the environmental conditions and the room temperature 

required.

Change of gas type 

Our boilers are designed to function either with Natural Gas (meth-

ane) or L.P.G. gas. If you need to changeover from one gas to the 

other, one of our Authorised Service Centres should be contacted.

Maintenance

Schedule an annual maintenance check-up for the boiler with a 

competent person.

Correct maintenance always results in savings in the cost of 

running the system.
