A control responds to impedance and temperature between active and return electrodes of the electrosurgical generator during tissue desiccation. Tissue contacts separately and independently provide high frequency power to effect tissue electrosurgically. An instantaneous impedance monitor between each contact and the return electrode signals. A regulator receives the signals and separately and independently controls tissue impedance at each contact in accord with signals to change independently the power to the return electrode. A temperature sensor for each contact transmits its temperature to the generator to regulate power to each contact. A first multiplexer provides high frequency electrosurgical power separately and independently to each contact from the generator. A second multiplexer relays temperature amounts of each contact to the generator. A method of control responds to tissue impedance by supplying high frequency power separately and independently to contacts, monitoring, regulating and controlling impedance between the contacts and the return electrode to set the generator power applied by each contact. Transmitting temperature amounts for each contact with sensors regulates contact power.
