State 3 is 'Operate up zone'.
State 4 is 'Extreme up zone'.
etlz_clr – Extreme low zone threshold clear is enforced to have value of '-273'. Module doesn't operate in such
temperature, but this value is logically set in order to define clearly 'thermal state' to temperatures below -40 deg.
etuz – Extreme up zone threshold is enforced to have value of '528'. Module doesn't operate in such temperature,
but this value is logically set in order to define clearly 'thermal state' to temperatures above 100 deg.
"#TEMPMON" set command changes field "actions" to "mitigate" or "none" to all zones.
All above parameters are saved in a configuration file in the module file system.
Examples:
AT#TEMPCFG= -273,-33,3,-35,-28,2,-30,80,0,78,90,3,88,528,3
OK
Explanation:
zone Thr_clr Thr Action info
'Extreme low zone' -273 -33 3 – emergency call only
'Operate low zone' -35 -28 2 – TX backoff
'Operate normal zone' -30 80 0 – no mitigation
'Operate up zone' 78 90 3 - emergency call only
'Extreme up zone' 88 528 3 - emergency call only
All zones have hysteresis and free temperature range.
