Parameter List
Use Down/Prg key to enter program mode,
Use Up, down, set keys to change values of parameters.
Min : MINIMUM Max : MAXIMUM
Fact. Set : FACTORY SETTING(DEFAULT)
Description of parameters and functions.
Sr.No. Parameter
P2 Function: To set maximum allowable high
01
temperature limit and alarm.
To change the parameter value, Use UP/DOWN keys to set desired
press set key. range.
Once set at a particular range, this will
not allow the set point to go above this
range.
Example: Setting this parameter at
99.9 C will not allow the set point to go
Range
above 99.9 C. Also if the temperature
Min Max Fact. Set
reaches or goes above 99.9 C.the display
will show High Temp. Alarm & at this point
0 0
P3+1.0 99.9 C 99.9 C
the alarm will activate.
P3 Function: To set minimum allowable low
02
temperature limit and alarm.
To change the parameter value, Use UP/DOWN keys to set desired
press set key. range.
Once set at a particular range, this will not
Range
allow the set point to go above this range.
Example: Setting this parameter at -50 C
Max
Min Fact. Set
will not allow the set point to go below
0
-50 C. Also, if the temperature reaches or
0 0
-50 C P2-1.0 -50 C
goes below -50 C the display will show
Low Temp. Alarm and at this point the
alarm will activate.
Note : Below -9.9 C, resolution automatically
change to 1 C .

Description of parameters and functions.
Sr.No. Parameter
P4 Function: To set differential for
03
temperature.
To change the parameter value, Use UP/DOWN keys to set desired
press set key. range.
Example: If the set point is set at 10.0 C
and differential is set as 2.0 C, then when
Range
t h e s y s t e m r e a c h e s 1 0 . 0 C , t h e

compressor will cutout. Since differential
is 2.0 C, the compressor will cut in(restart)
0.5ºC 20.0ºC 2.0ºC
at 12.0 C (10.0 C + 2.0 C).
P5 Function: To set temperature probe
04
calibration.
To change the parameter value, Use UP/DOWN keys to set desired
press set key. value.
Example: If the actual temperature is
20.0ºC and the temperature on the
Range
controller shows 22.0ºC set this
Min Max Fact. Set parameter to -2.0 C and once out of this
mode, the temperature will display
-9.9ºC 10.0ºC 0.0ºC
20.0ºC. (22.0ºC-2.0ºC).
H2 Function: To set maximum allowable high
05
alarm limit relative Humidity.
To change the parameter value, Use UP/DOWN keys to set desired
press set key. range.
Once set at a particular range, this will not
allow the set point to go above this range.
Example: Setting this parameter at 100%
will not allow the set point to go above
Range
100%.Also if the humidity reaches or goes
Min Max Fact. Set
above 100%. the display will show High
humidity Alarm & at this point the alarm
H3+1 100% 100% will activate.
