1) Setting of the decimal place has an impact on this parameter.
) Note When using the controller as a pure floating controller or modulating controller without
the burner release function (Q13, Q14), parameter «HYS1» must be set to
0 and
parameters «HYS2» and «HYS3» must be set to their maximum values.
→ Otherwise, e.g. when using default parameter «HYS1» (factory setting -5), the
floating control loop will only be released when the control deviation reaches -5 K.
