1 Snowflake-symbol with a clock in its center 2 Red LED is on (alarm)
3 Temperature of the active DCU
As soon as the first DCU reaches the 0 °C (32 °F) temperature limit, the thermometer-sym-
bol changes to a snowflake-symbol. The clock in its center stands for the start-up phase of
the active DCU. The EC-30C is still in alarm modus (red LED is on), because the DCU has not
reached its target temperature yet.
