For absolute alarm, if cabinet temperature sensor value is lower than temperature alarm minimum
parameter value and for relative alarm, if cabinet temperature sensor value is lower than
(Temperature Set - ), then message starts to blink.If buzzer function selection
parameter is 2 or 4, internal buzzer starts to operate.
