Operation manual for M RS 420 ESTYMA control unit 

4

 

Thanks  to  an  advanced  operation  algorithm  and  the  possibility  of  controlling 
numerous  parameters,  the  unit  can  be

  very  flexibly  adjusted 

to  the  needs  of 

the heating system.  

The  controller  has  an 

output testing  function.

  The  function  is  available  in  the 

MAINTENANCE  MODE  and  it  allows  to  check  the  correctness  of  electrical 
connections and the working order of the controlled equipment (pumps, blower, 
feeder, mixing valve actuator) prior to starting the boiler. 

A

  large  alphanumeric  display

  facilitates  communication  between  the  unit  and 

the user and the interface is very easy to use.  

new intuitive menu in several languages

: Polish, English, German, French, 

Lithuanian, Russian. 

Lambda  sensor

  ensures  optimum  supply  of  air  to  the  combustion  process, 

thereby  simplifying  the  work  of  the  operator;  it  also  reduces  fuel  consumption 
and  improves  combustion,  reducing  emissions  of  harmful  substances  to  the 
environment (optional boiler equipment). 

The 

pneumatic fuel feeding

 control system allows the boiler to operate for long 

periods of time without the need to add fuel. 

The 

heat  exchanger  cleaning

  control  system  ensures  that  the  boiler  retains 

high efficiency without the need to clean the exchanger.

unit.
