P5 To change Use UP/DOWN keys to set
the P5 desired value. In time it may be
parameter, possible that the display may
press the be offset by a degree or so.
SET key To compensate for this error,
you may need to add or minus
the degrees required to achieve
the correct temperature.
Setting value is from -
0 0
10.0 C to + 10.0 C
Example: The temperature on
0
the display is 28.0 C, whereas
0
the actual temperature is 30.0 C.
You will need to set the P5 mode
0
to 2.0 C, which means that once
out of the programming mode,
that once out of the programming
mode, the temperature will show
0 0 0
30.0 C (28.0 C + 2.0 C).
6 P6 parameter Function: To set time delay
between compressor relay
restart time.
P6 To change Use UP/DOWN keys to set
the P6 desired value. This parameter is
parameter, used to protect the compressor
press the from restarting in a short period
SET key. of time and can be set between
0 to 20 minutes.
Example: If this parameter is
set at 3 minutes, the relay will
cut off at the set temperature, but
will cut off at the set temperature,
but will not restart for a minimum
of 3 minutes, even if the
differential is achieved earlier.
This parameter is good to protect
the life of the compressor or
even in applications where the
probe is placed at places where
there are sudden & short in
temperature like above a cold
room door.

Example: If the set point is set

P3 To change Use UP/DOWN keys to set

SET key value and above P2 setting.
Example: Setting this parameter
0
at -30.0 C will not allow the set

point to go below -30.0 C. Also,
if the temperature reaches
0
-30.0 C, the display will show
Lt(Low Temp) indicating that the

the value in this parameter and
at this point the buzzer will
come on.
