After the soft start stage, the thermo- controller automatically sets itself to the specified heat output. As opposed to phase-fired control, half sine wave control is based on com- plete half-cycles. Interconnecting 3 output channels allows complete sine waves to be picked off the mains, thereby substantially reducing harmonic perturbations of the electrical power mains. Load power variation between 0...100% in steps of 1%. Mains Voltage Correction E774D 01/08/2011 8.8 Module Control Information about actively selecting error suppression using the inhibit signal, cf.
