ok thanks. I notice my AR550 upper temperature range was set very high and lower range was set very low. Any ways of configuring this? If i'm not wrong the upper limit was 100degree celcius and lower limit is 0 degree celcius. I want to set the upper limit to just 80 degree as the current temperature of my AR550 can fluctuate around above 70degree celcius and i want it to raise an alarm for this
