When PID control is selected, this places a limit on the
output demand from the PID which can be applied to the
heating circuit.
‘OP.LO’ can be set up in the same way if required.
If on/off control is selected these parameters do not apply.
They are replaced by ‘HYST.H’ and ‘HYST.L’ to set the
difference between the output switching off to switching
on.
