The LSn and LAn parameter are used only to show the actual settings (read only). See Figure 9-2 for an example of configuration:
9.1.1. Daily Defrost From RTC: [EdF = rtC]
• IdF Parameter: For safety reasons, force the value of Idf at +1 with respect to the interval between the two Ld parameters.
The IdF timer is restarted after defrost and at every power ON.
• DEFROST START: At the time selected by the parameters Ld1 to Ld6 or Sd1 to Sd6.
• DEFROST END: If the probes reach the dtE temperature or for maximum MdF time.
• SAFETY and RtC or RtF ALARM: With clock alarm, the device will use the parameters IdF, dtE and MdF.
• MULTIMASTER DEFROST: All the probes with real-time clock function:
