When set to “ ”, all
parameters are programmed to
factory set values.
Useful to debug setting related
problems.
Once the set key is pressed,

Example : Setting this
O
parameter at 20.0 C will not
allow the set point to go
O
below 20.0 C. Also, if the
O
temperature reaches 20.0 C
or goes below, the display will
show Lt (Low Temp)
indicating that the
temperature has gone below
the value in this parameter.
Operating messages
Description
Temperature equal or above the maximum limit of the set point.
(“ ”)
Temperature equal or below the minimum limit of the set point.
(“ ”)
Probe circuit open or without probe, or for temperature out of
given range.

Use UP/DOWN keys to set
desired range. After setting the
desired range, press the set key
and you will see "- - - -” which
confirms that the value has been
stored in memory.
This parameter locks the keypad
so that tampering is not possible
by bystanders.
= keypad unlocked
= keypad locked
When locked , all the parameters
can only be viewed, but can't be
modified. When you enter the
parameter it will display “ ”
and then it will show the value of
parameter.
To change
the “ ”
parameter
press the
SET key.

Press RST key to come out of Program/Set mode immediately.
If Controller is in Program or Set mode and RST key is
pressed it will come to the normal mode.

the display is 28.0 C, whereas
the actual temperature is
O
30.0 C. You will need to set the

O
temperature will show 30.0 C
