PRINCIPLE OF OPERATION CONT.
also eliminates the problems caused by stagnant water.
Trouble-free performance and minimum maintenance
are assured by the design features of the EnviroAire IAQ
humidifier. All humidifier housing parts that come in contact
with water are non-metal and will never rust or corrode.
Neither heat nor water will affect them under normal
operating conditions.
The Water Panel evaporator, designed especially for uniform,
high evaporation, and the Scale Control Insert (which encases
the Water Panel) effectively traps mineral deposits which
are often the cause of damage to working parts in ordinary
humidifiers.
The Water Panel evaporator is the heart
of the humidifier and must be in good condition to
assure high capacity trouble-free performance. It
should be changed at least annually.
The distribution tray incorporates a synthetic fabric liner that is
designed to deliver water uniformly over the entire top surface
of the Water Panel evaporator, provided the humidifier is
mounted level. It is normal for some mineral deposits to form
in the distribution tray as it dries out between humidification
cycles. These deposits can actually help distribute water
in the tray, but if they block the openings, they should be
removed as described in the “Periodic Maintenance” section
of this manual.
Your Digital Humidifier Control works in conjunction with
your HVAC system to control the operation of the humidifier.
The control senses indoor RH and outdoor temperature and
automatically adjusts the operation time of the humidifier to
provide the optimum humidity level in the home.
The Automatic Control can be set to turn on the HVAC blower
when humidity is required. Plumbing the humidifier to hot
water is required for this mode of operation.
The digital readout on the control displays the RH level inside
the cold air return duct. RH is a measure of the amount of
moisture in the air as a percentage of what the air can hold.
Warm air can hold more moisture than cold air can.
The control has lights which indicate humidifier operation,
when the Water Panel needs to be replaced and when
service is required. See “Operating Instructions” for more
information.
There are many humidifiers on the market. They all add
moisture…with varying degrees of efficiency. None,
however, offer the features, design, and performance
incorporated into your new EnviroAire IAQ humidifier.
OPERATING INSTRUCTIONS
The Digital Humidifier Control offers two modes of operation,
Automatic or Manual. An explanation of both modes follows.
(See the following page: Figure A for Automatic Mode.
Figure B for Manual Mode.)
When in the Automatic Mode, this system offers the following
benefits:
• You will always receive the optimum amount of humidity so
that your home and its furnishings are always protected from
the damaging effects of excess condensation or low humidity
during the heating season. The Control automatically
adjusts your home’s RH based on the outdoor temperature,
increasing the time maximum comfort is maintained.
• Simple operation with few adjustments. The Control
eliminates the need to manually adjust the control when
outdoor temperature changes. It also eliminates the need to
turn the dial setting to “OFF” during the summer season.
Call Dealer for Service:
The red light indicates that
the humidifier is not operating normally and that service is
required.
Change Water Panel:
The yellow light indicates that it is
time to change the water panel in the humidifier.
Humidifier On:
The green light indicates that the humidifier
is operating normally.
DIGITAL CONTROL INDICATOR LIGHTS
“Blower Activation Switch” to “ON” to allow the humidifier
control to activate the HVAC fan for maximum humidification.
For this setting the EA-655 must be connected to hot water.
If the HVAC system has been idle for one hour, the humidifier
control will activate the HVAC system fan to sample the air for
3 minutes. If the RH is lower than the set point, the humidifier
control will activate the humidifier and keep the fan running.
