(Unit: this value indicates the type of setting for the unit; this type can be:
— SINGLE: unit without Master/Slave connection;
— MASTER: identifies the master unit;
— SLAVE: identifies the slave unit;
Power step: the required power calculated by the thermostat is divided between
the master and slave units based on this parameter; (E.G.: 1% = the units work in
parallel; 100%= the units work in sequential mode (first all the power of one is used
0003 and then all the power of the other is used);

slave unit; this management can be:
— YES: the slave pump turns off if there is no request on the slave;
