I apparently don’t understand the alarm settings as the alarm light is always on. What I would like is for the alarm to activate if the temperature is over or under the set temperature by 10 degrees. Not sure what dhAl and dlAl settings do and have them set to 0.

Hello,  
Please refer to:  
HiAL: alarm when measured value is larger than HiAL (PV\>HiAL).  
LoAL: alarm when measured value is smaller than LoAL (PV＜LoAL).  
dHAL: alarm when plus deviation is larger than dHAL (PV\>SV+dHAL).  
dLAL: alarm when minus deviation is smaller than dLAL (PV\<SV-dLAL).
