The controlled system data recorded for the forced oscillations are used to calculate the
controller parameters «rt, dt, Pb.1» and a filter time constant for actual value filtering
that is optimized for this controlled system.
− High-fire operation in the «modulating burner» mode
− The thermostat function (relay 1) must be constantly activated, otherwise «tunE» will
be canceled and no optimized controller parameters will be adapted
− The above mentioned actual value oscillations during self-setting must not exceed the
upper threshold of the thermostat function (increase if necessary, and lower the
setpoint)
