Brownout Detection Mode
To adjust the brownout detection mode, press the
SERVICE key and navigate to "Brownout Detect" on the
digital display. You can then use the UP and DOWN keys
to choose from three options: 230V, 208V, or Disabled.
Enabling brownout detection will cause the unit to shut
down automatically if the Transformer's 24VAC signal
drops below a certain threshold, specifically below
21VAC for 230V or below 24VAC for 208V. This function is
intended to protect the unit from low voltage situations. If
you prefer not to use this feature, simply select "Disabled".
The default setting for brownout detection is 230V.
