The message "AFr (network frequency alarm)" for the DIXEL IPC400D SERIES means that the network frequency is different from the value configured in parameter SP11. This triggers an alarm with the relay and buzzer activated, and other loads are turned off. The alarm resets automatically when the frequency returns to the set range or when network frequency control is disabled by setting SP11 = 2.

The message "NETWORK FREQUENCY ALARM" (display label AFr) for the DIXEL IPC400D SERIES means that the network frequency is different from the configured value in parameter SP11. This alarm activates the alarm relay and buzzer, and turns off other loads. It resets automatically when the frequency returns to the set range or when network frequency control is disabled by setting SP11 = 2.

    USER MANUAL – Release 1.2 of 01/01/2010 Page 129 of 191 Version: 02/03/2010 WORKING OF THE BOILER HEATERS DURING THE DEFROST CYCLE The parameter Ar05 establishes working of the boiler heaters (anti-freeze) during the defrost cycle. If the value is 0 during the defrost cycle the heaters are only activated by their temperature control. If the value is 1, the heaters are always on during the defrost cycle: they switch on when the reversing valve converts working from heating to cooling and they switch off when the dripping time has ended and the compressor re-starts.
