AtS complements the AtO reading by providing further
Set-Point function selection information as follows:
Set-Point Function AtS Value
C-H 217
C-L C-L
PID 231*
* If the Set-Point function has been set to PID, AtS will
display a value. The default value is 231, more on this

SetUp
AbS is the maximum temperature the boiler has reached.
The example below, 200C (See 2.15 Temperature Units)
would be the maximum temperature recorded by the
ARP since the last time that AbS was cleared.
Please see section 7.3 for detailed information.
By pressing the SetUp button, the AbS value will be
cleared. When the AbS value has been cleared, -LO will
flash on the display until the control is put into the ARP
mode to record a new maximum value.
Any changes must be stored, see 2.22 Store Setting.
Please note that if AbS is greater than 250°C (482°F)
there may be a wiring or cooling unit issue, please
contact ARP technical support.
2.7 tr Process Value
Tr is the number of times that the ARP Control has
triggered since the value was last cleared. The following
example shows that the ARP turned off the fridge twice:
Please see section 7.4
for further info.
Push the SetUp button to zero the tr value. Also see 7.4

Any changes must be stored, see 2.22 Store Setting.
