To desable this function, 
enter 0 (zero) on parameter 23 
. 
Recovery function is particularly useful 
for temperature control on kilns. At 
restarting after a power failure ATR620 
can resume the interrupted cycle, 
assuring optimal cycle execution.   
4.  Power failure during a rising step: 
recovery gradient will be the same 
as the step in progress. Setpoint 
value will be the same as sensor 
temperature.  
5.  Power failure during a dwell 
(holding step): two options are 
available. If the gap process-
setpoint is not bigger than value 
entered on P-22, cycle will be 
resumed from the point of 
interrumption. If the gap is bigger 
than this value, cycle will be 
resumed from previous step and 
will follow point1.  
6.  Power failure during cooling steps: 
setpoint follows the temperature of 
sensor and controller will not 
foresee any rising step (safety 
feature for glass kilns) , skipping to 
next step if required.   
** After a power failure chronometer 
always starts from 00:00
