Temperature Commands
Command:
s
Function:
Return Set Point Temperature
Description: When the command s<CR> is received by the RIC40 unit, the current set point temperature
will be returned in a text string terminated by <CR><LF>. The setpoint format length is variable
depending on the number of digits in the setpoint temperature and whether the value is negative. The
value will always include a decimal point and one character representing the fractional tenth value. If the
command is not received in the proper syntax, e<CR><LF> will be returned.
Note: Putting the RIC40 into Idle Mode (see “Command: i”) will turn off the temperature controller and the
set point will be read as “off”.
Example—Return the current set point:
send: s<CR>
returned example 1: -10.0 <CR><LF>
returned example 2: 9.3 <CR><LF>
returned example 3: 100.0 <CR><LF>
returned example 4: off<CR><LF> if unit is in Idle Mode (see “Command: i”)
Command:
n
Function:
Set and Store New Set Point Temperature
Description: When the command n(new_temperature)<CR> is received by the RIC40 unit, the set point
will be changed to new_temperature and the text string “ok” will be returned terminated by <CR><LF>.
The format for new_temperature is variable depending on the number of digits in the desired new set point
temperature and whether the value is negative. The value must always include a decimal point and one
character representing the fractional tenth value. The settable range is -10.0C to 100.0C.
If the command is not received in the proper syntax, e<CR><LF> will be returned.
Example1— Change set point to -10.0C:
send: n-10.0<CR>
returned: ok <CR><LF>
Example2 – Change set point to 9.3C :
send: n9.3<CR>
returned: ok <CR><LF>
Example3 – Change set point to 100.0C :
send: n100.0<CR>
returned: ok <CR><LF>
