or blank (the command is not available if the controller is in
setup mode)
Note
If the controller is not in control or idle mode and the tem-
perature reading is requested through the TMR command,
the controller answers with the last acquired reading when it
was in control or idle mode.
Following are examples of commands for setup items:
“01200<CR>” “01200<CR>” “01200<CR>” “01200<CR>” “01200<CR>”
This command sets the setup item 22 (relay 2 set point) of a
EC controller, identified by the process ID number 03, to the
+12.00 mS value.
