About your new thermostatLED light indicators
The LED light panel on the TrueSTEAM lets you know that the humidifier is operating correctly,
when maintenance is needed, and when it is safe to remove the tank for cleaning. The push but-
tons allow the tank to be drained for cleaning, and quickly return to operation when the tank is
reattached to the humidifier.
Power indicates the TrueSTEAM is plugged in and that the humidifier is
ready for operation.
Humidifying indicates that steam is being delivered to the home.
Clean Tank: This LED blinks to indicate the TrueSTEAM is draining when
you press the EMPTY button. When the light is on solid (not blinking), the
tank is empty and safe to remove for cleaning.
Call Service is a fault indicator. Call your HVAC technician to service the
humidifier. HVAC technicians: Refer to page 12 for fault identification and
troubleshooting.
Press Reset will blink when power is applied or reapplied (upon initial
installation or after cleaning). This is a stand-by mode to ensure water
lines are hooked up properly before unit resumes operation. This will blink
for 5 minutes before going to system ready. The 5-minute default can be
overriden by the installer by pressing the RESET button.
Press Empty will blink to indicate that the water tank needs cleaning. Push
the EMPTY button to drain the tank for safe removal and cleaning.
Reset Button If the Press Reset light is blinking, press the RESET button to
override the 5-minute delay at startup. If the Call Service LED is on (fault is
present), press/release the RESET button to blink a diagnostic code on the
Call Service LED. Press/Hold the button for 5 seconds to clear all faults and
reset “Clean Tank” timers. If the Press Empty LED is blinking, press/hold the
RESET button for 5 seconds to turn off the Press Empty LED and restart the
Clean tank timer.

service. Do this before servicing the tank and internal parts.
