*NOTE: NHP does not display actual message or error.
- Remote indication 61-20 “yellow” means humidifier has shutdown and one of several system messages is showing.
The exception is on the NHP when No Current or Output Too Low is the fault, 61-20 “yellow” will be off, but the yellow
light on the NHP will be on.
- Remote indication 62-40 “green” means contactor is on; humidifier is operating.
- Remote indication 63-36 “red” means cylinder is spent; replacement is necessary.
