P1 and P2 
You can check how many times the unit has been switched on, and look at 
the date and time of the last ten starts. This can be useful if there have been 
power failures or if  for  any reason the  Ultra Twin restarts  due  to  a  fault 
condition.  The  Ultra  Twin  can  be  backed  up  from  a  battery  which 
automatically  cuts  in  during  power  failure,  battery  backed  up  units  will 
continue  uninterrupted  operation  and  therefore  will  not  register  a  loss  of 
mains  power.  If,  however,  the battery  were  to  fail  during  a  mains power 
interruption, a start up would be recorded once power has been restored. 
The following parameters can be accessed by directly entering the parameter 
number.  To  do  this,  enter  the  program  mode  and  then  type  in  the 
appropriate parameter number. 
P*940 Number of Starts 
This parameter shows how many times the unit has been powered up. 
P*941-P*960 Start Date & Time 
Parameters P*941 and P*942 show the date and time that the unit was last 
started. There are ten start dates & times recorded, which are parameters 
P*943-P*960. The first on the list are the most recent, and the last ones are 
the oldest. These are read only, and cannot be changed.
