together for about 2 seconds or by 2-way instructions. The baud rate will not change from the last value when
this is done. Factory defaults can be installed with a RS485 command (#XF).
** These parameters can be adjusted both by a RS485 command, which allows you to scale the high and low
temperature points to suit your application.
*** Communications Mode and RS485 Mode, like Baud Rate, are unchanged when the factory defaults are restored
