working.
c.
For verifying the amount of moisture being produced measure the air
conditions before the DTA and then downstream of it. You should measure
both a decrease in dry bulb temperature and an increase in relative humidity.
Plot these on a Psychometric chart or call the Factory for further interpolation.

a.
Moisture migrates very quickly. Make su

foreseen sources of outside air have been introduced to the space being
humidified as this will increase the load on the humidifier.
b.
Verify that the blower fan is turning on when there is a call for humidification
and not just when there is a call for heat. There is a dry contact relay in the
panel for exactly this purpose. Contact the Installer to verify that he utilized
this relay and that the cont
has been set up to run the fan only when there is a call for humidification.
Also make sure that the necessary zone dampers are also opening to allow
moisture to be delivered to the appropriate spaces.
c.
Make sure the air filters to the furnace/blower/heat pump are not completely
clogged and restricting air flow.
d.
Verify that the amperage draw for the 120VAC and 48VAC side of the circuits
are at or near the rated amount for that system. If it is below the labeled
ratings then some of the UPC
this is the case.
