“heating only” boilers;
2- W hen the parameter value 01, 02 and/or 03 is set, parameters from no.17 to 22 are automatically activated and boiler settings are carried-out in
through these parameters (in Hz). Once the parameter value has been set according to the boiler output, the P.C.B will automatically adjust the
maximum and minimum values.
