HE-6800 Series Humidity Transmitters with Temperature Sensor Installation Instructions4
Setup and Adjustments
Controller Configuration DIP Switch and
LED Mode
A DIP switch configures the HE-6800 for use with the
desired controller by enabling or disabling the manual
override PB and the LED. To change the controller
mode, use the three position DIP switch located on the
PCB. See Figure 4 and consult Table 2 to determine
the controller compatibility.
For all transmitter models, the factory default
LED mode is LED Mode:ON. The DIP switch positions
enable/disable the functions listed in Table 3.
