Command:
i
Function:
Set IC20/25 Unit to Idle Mode
Description: When the command i<CR> is received by the IC20/25 unit, the temperature controller will be
switched “off”, meaning that the plate will no longer heat or cool. In Idle Mode, the unit will report a set
point of “off”. To exit Idle Mode, use command I (see below) or set the set point to a new value using
cmd n. If the command is not received in the proper syntax, e<CR><LF> will be returned.
Example – Set Idle Mode:
send: i<CR>
returned: ok <CR><LF>
Example – verify Idle Mode:
send: s<CR>
returned: off<CR><LF>
Example – exit Idle Mode by setting new set point to 25C
send: n25<CR>
returned: ok <CR><LF>
Example – verify no longer in Idle Mode and set point is 25C:
send: s<CR>
returned: 25<CR><LF>
Command:
I
Function:
Clear IC20/25 Idle Mode and Return to Last Set point
Description: The command I<CR><LF> will exit Idle Mode and return the IC20/25 set point to the value
that it was before the unit entered Idle Mode. If the command is not received in the proper syntax,
e<CR><LF> will be returned.
Example – verify Idle Mode:
send: s<CR>
returned: off<CR><LF>
Example – Clear Idle Mode (set point was 25C before entering Idle Mode):
send: I<CR>
returned: ok <CR><LF> (set point now 25C)
Example – verify no longer in Idle Mode and set point is 25C:
send: s<CR>
returned: 25<CR><LF>
Command:
p
Function:
Return the current Plate Temperature
Description: When the command p<CR> is received by the IC20/25 unit, the current plate temperature will
be returned in a text string terminated by <CR><LF>. The format length is variable depending on the
number of digits in the plate temperature and whether the value is negative. If an internal RTD
temperature sensor or calibration error has occurred, the specific error code will be returned as indicated
in the following table. If the command is not received in the proper syntax, e<CR><LF> will be returned.
See Command: #F or Figure 17 to reset cal points if a calibration error has occurred
Example—Return the plate temperature:
send: p<CR>
returned example 1: -10 <CR><LF>
returned example 2: 9 <CR><LF>
