NOTES:
1 - Activate only for “heating only” water heaters;
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 water heater 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 water heater output, the P.C.B will automatically adjust the maximum and minimum values.
