mode the heater is started and stopped by the buttons on the panel above (manual run control). Pressing the AUTO
RUN button will switch to auto run mode and the heater will start and stop via an external input. This can be float
switches in a storage tank, a remote run control relay or a remote run bit via Ethernet connection.
NOTE:
If running the heater in MANUAL mode it will not STOP unless the STOP button is pushed. Constant
monitoring is required running in this mode.
