6. Humidifer won't spray
Check the red LED on humidifier, which must be viewed
straight on. When the light is on the humidifier is attempting to
to spray. If there is no spray, check the nozzle for blockage
- if blocked remove and rinse or replace the nozzle. If the
light never comes on, the humidifier is not receiving a signal
to spray, or has no power. Check the controller to make
sure there is a humidity demand - on the humdistat three
raindrops will appear when it is calling for the humidifier to
spray, on the intellistat a small vertical bar will appear in the
lower left corner of the screen. If the symbol appears, check
the wiring or, if using the humidistat, see below.
7. Raindrops appear on the humidistat but the
humidifier won't spray.
There may a compatibility problem with the furnace.
Add a pilot relay with the coil connected to W and C
on the furnace and the contacts to HUM and R on the
humidistat. This will isolate the humidistat from the 24
VAC and solve the problem. Humidistats manufactured
after 5/00 have built in isolation.
8. What are the R and C terminals for on the Humidifier?
These terminals are merely tie-off points provided for
convenience. It is not necessary to connect them to
anything.
