AUX output is 20mA, and user can’t limit the maximum AUX output to 10mA.
oPH
Output upper
limit
OPL limits the maximum of OUTP (main output). OPH should be greater than OPL.

AL P
Alarm output
allocation
From right side to left side, the first, second, third and fourth digit of ALP individually
indicate the alarm output terminal of HIAL, LoAL, dHAL, and dHAL. 0 shows no
output. 1 and 2 are spare for future use. 3,4,5 and 6 respectively indicate alarms
outputted to AL1, AL2, AU1 or AU2. For example,
ALP = 5 5 0 3
LoAL HdAL LoAL HIAL
It shows that HIAL is sent to AL1, LoAL has no output, HdAL and LdAL are sent to
AU1.
Note 1: When AUX is used as auxiliary output in bidirectional (heating/refrigerating)
control, alarm to AU1 and Au2 won’t work.
Note 2: Installing L5 dual relay output module in ALM or AUX can implement AL2 or
AU2 alarm.

CF
System
function
selection
CF is used to select some system function. The value of CF is calculated as below:
CF=A×1+B×2+C×4+D×8+E×16+F×32+G×64+H×128
A= 0 , reverse action control mode. When this mode is selected, an increase in PV
