parameter "Response rate" (set in the "Quick commissioning" wizard). The rate parameters
automatically adjust when parameter "Response rate" is altered, but any changes made to the
rate parameters following the completion of the wizard will supersede the response rate
setting. See menu Rate (2.1.8).
