5. REGULATING THE APPLIANCE
5.1 Parameters table
NOTES:
1 - Activate only for “heating only” boilers;
2 - If the heating system has more than one zone, an additional interface board (optional extra) must be installed on the
circuit board and parameter 15 set at 01;
3 - To install the telephone control, use non-polarised conductors connected to contact TA of the terminal board in
parallel with the remote control if fitted. Set the parameter 16 at 01.
4- When the parameter value 01/02/03 is set, parameters from no.17 to 22 are automatically activated and boiler
settings are carried-out in through these parameters (in Hz) that replace parameters from no.9 to no.
Once the parameter value has been set according to the boiler output, the P.C.B will automatically adjust the
maximum and minimum values.
