AFT PROBE STATUS
LOW TEMP ALARM
Use UP/DOWN keys to set desired value.
Disable = It disables the Antifreeze Trip
function of the controller.
Enable = It enables the Antifreeze Trip
function of the controller.
Use UP/DOWN keys to set desired
value.
SET = Chiller Set Temperature.
AFT = AFT Set Temperature.
EXAMPLE :
Setting this parameter at
0
15.0 C will not allow the set point to go
0
below 15.0 C Also, if the temperature
0
reaches or goes below 15.0 C the
display will show Low Temp. Alarm and
at this point the alarm will activate.

parameter,press the set key.
Example :
If this parameter is set to 20
Min, once the unit is powered on the Ht
alarm will not activate for 20 minutes even
if there is a fault. This is very useful to
eliminate the nuisance alarm when a unit
is switched on.
Use UP/DOWN keys to set desired value.
This parameter sets a time delay on
power on for the Ht alarm.

EXAMPLE :
If this parameter is set at 3
minutes, the compressor will cut off at the
set temperature, but will not restart for a
minimum of 3 minutes. This time delay is
also effective at 'Power On’
of the system.
This safety feature is used to protect the
compressor from restarting within a short
period due to power fluctuations.

HIGH TEMP. ALARM
SET = Chiller Set Temperature.
Use UP/DOWN keys to set desired value.
Once set at a particular value, this will not
allow the set point to go above this value
and below Low Temp Alarm setting.
EXAMPLE :
Setting this parameter at
0
25.0 C will not allow the set point to go
0
above 25.0 C. Also if the temperature
