The HM700 user interface includes 2 LEDs that provide information about the humidifier status.
Yellow and Green LED Flashing.
Indicates there is no request for humidity.
Yellow LED Flashing.
Fault detected, humidifier has stopped operating.
Green LED Flashing.
Indicates the humidifier is powered, but the control
equipment (stat, air proving, fan, etc.) has interrupted
the call for humidity.
Yellow LED On.
Indicates that water level is high. When the yellow LED
is steady on (not flashing) it indicates that the high
water sensor has interrupted filling of the cylinder. The
LED is on for information only and unless it persists
for an extended period of time, it does not require any
action.
Green LED On.
Indicates steam is being produced.
