need to be cleaned or replaced. Press and hold the power button for 5 seconds to reset the
maintenance clock. Some units feature a red LED that will light after 3 months if the initial
service reminder is not turned off.
OPERATION FOLLOWING A POWER INTERRUPTION
If the electrical service to the ventilator is for some reason interrupted, the mode of operation
active in the wall control at the time of the interruption will resume when the electrical service to
the ventilator resumes. Any custom settings will have been saved.
CUSTOM SETTINGS
The control allows adjustments to customize its use for unique circumstances. Any of these
changes are written into the control’s memory but can be changed an infinite number of times.
We recommend that only a qualified technician make these adjustments as they can affect the
nature of the ventilator’s performance. The customizable features include:
1. Adjusting the run time of the maintenance clock
2. Calibrating the humidity sensor
3. Turning off/on recirculation functions.
To access the custom settings menu, simultaneously press and hold the up and down arrow
buttons for 15 seconds. You will note that the backlight would have turned on after 10 seconds.
Once in the custom settings menu, use the arrow buttons to navigate among choices for a
given setting. Pressing the mode button will preserve factory settings or initiate any change
and will move you on to the next customized feature. After 5 seconds of no button activity,
current settings will be written and the control will resume regular operation as programmed.
ADJUSTING THE RUN TIME MAINTENANCE CLOCK
Once you are in the custom settings mode the first option will be maintenance
clock. You will see the factory setting of this feature: 3 months. To keep factory
setting, press the mode button or use the up and down arrow buttons to change
the setting in the range of 1-12 months. Once any desired change to the setting
is in place (if any), press the mode button.
CALIBRATING THE HUMIDITY SENSOR
If calibration is not desired, skip this step by simply pressing the mode button
to keep factory calibration active. If calibration is desired, use the up and down
arrow keys to calibrate the humidity sensor in 5% increments. To program any
changes, press the mode button.
TURN OFF/ON RECIRCULATION FUNCTIONS
You will now see an animated recirculating arrow indicating that the
recirculation by factory default is enabled. Use the up and down arrow keys to
turn off the recirculation functions (static arrow) or on (animated arrow).
As noted previously, recirculation functions must be turned off for use with ventilators that do
not have a recirculation damper. For such units, use of recirculation functions would only result
in full-time, low-speed operation.
SECTION 11
Status LED
1. Your control board is equipped with status lights to indicate mode of operation as follows:
SECTION 12
Start-Up
1. Ensure the controls are connected in accordance with Section 7 and/or 10.
2. For electrical hook-up, plug into a properly grounded 120 volt receptacle.
3. Ensure that the machine is piped to an adequate drainage source, i.e. through the drain
hose supplied.
SECTION 13
Operating Your System
It is recommended that the unit run on low speed at all times to ensure a steady supply of
fresh air and removal of indoor pollutants. How much a home needs ventilation can depend
on several factors such as number of inhabitants, cooking habits, hobbies, presence of pets,
opening windows, etc. so no two households are necessarily the same for the amount and
frequency of ventilation they need. Observance of moisture on windows, lingering odors and a
sensation of stuffy, stagnant air are all signs for the need of ventilation in general or increased
ventilation in specific cases. The controls for your ventilation system offer means to regulate
how much and how often the home is ventilated.
The included control is equipped with a dehumidistat, or “d-stat”. A d-stat monitors ambient
relative humidity (RH) and has selectable settings, generally 30%-80% RH. When ambient
humidity is detected above the setpoint, it will trigger high speed in the ventilator. The unit
will run in high speed until the ambient air returns to the setpoint RH.
Your ventilator is not
a dehumidifier
, however ventilating can have a dehumidifying effect by simply removing
high RH air from the space, particularly during cooler/cold seasons when outdoor humidity is
typically lower than indoor humidity. Typical dehumidistat settings are as follows:
Winter Operation:
40% - 60%. Lower settings may be necessary in colder zones to keep
windows free of condensation. If you notice the air is uncomfortably dry in winter, you
might set humidity to a higher level or choose an operation mode above which operates
the ventilator less or for shorter periods.
Spring/Fall Operation:
50% - 60%.
Summer Operation:
For air conditioned homes run the ERV/HRV as recommended for
winter operation, i.e. continuous low speed or use a 20/40 setting. In homes without
air conditioning, there is no need to run the ERV/HRV during the day when windows are
open. If the ERV/HRV is connected to the bathrooms(s) or kitchen, use the standby setting.
The typical dehumidistat summer setting is 65%-80% or OFF.
SECTION 14
Use and Care
CAUTION:
MAKE SURE UNIT IS UNPLUGGED BEFORE SERVICING.
NOTE:
Exact location of components will vary according to the specific unit.
1.
Filters (A):
Dirty filters can reduce
ventilation efficiency, result in unbalanced
airflow and damage or shorten the life of
the motors. Filters are located either on top
or below the core depending on your exact
model and remove easily by opening the
front cover of the unit and sliding out.
Polyester Filters:
Vacuum every three
months. Replaced every 1-3 years.
Option MERV Air Filters:
If optional air
filters have been installed, they should be
replaced every 3 months. When replacing,
take special note of the airflow direction.
2.
Fan (B):
Wipe all parts with a dry cloth or
gently vacuum the fan. NEVER IMMERSE ELECTRICAL PARTS IN WATER. No other service
is required as these fans are designed to operate continuously without lubrication.
3.
Condensate Drain (C) (HRV UNITS
ONLY) :
Twice per year wipe clean
the condensate drain pan. Check the
condensate drain and tubing to ensure
they are free flowing. The tubing must
have an “S” or loop that traps a quantity
of water to prevent air from entering the
unit via this tubing.
4.
Recovery Core (D):
The core (located
behind the cover) should be removed and cleaned at least once a year. Unlatch the latch(es)
and slide the door to right to release from hinges and clean as follows:
ERV Units:
Clean by vacuuming at least once a year.
DO NOT USE SOAP, WATER OR ANY
CLEANING AGENTS ON THE FIBER-MEDIA CORE.
HRV Units:
Clean using a mild detergent in cold water at least once a year. Make sure
the core is completely dry before re-installing into the unit.
When re-installing the core make sure the arrow on the core is pointing to the top of the unit.
5.
Exterior Hoods:
Regularly check the outside vents and clean any obstructions such as
grass, leaves or other debris. Do not replace the screen with mesh smaller than 1/4” as
this will restrict airflow. During winter operation, ensure snow and frost does not build up
and restrict or block openings.
6.
Grills & Duct Work:
Clean the grills when they are dusty or greasy with soap and water.
Check for punctures in the insulation jacket on the fresh air and exhaust air ducts. Repair
any punctures using foil tape.
7.
Annual Servicing:
Your ERV/HRV should undergo annual general servicing by an
accredited contractor. This servicing should include the following:
a) The six maintenance items above.
b) A general check for proper operation. Controls and electrical connections should
be inspected.
c) Verification that intake and exhaust air flows are properly balanced.
d) Re-balancing as necessary.
CAUTION:
ONLY QUALIFIED TECHNICIANS SHOULD SERVICE CONTROLS
OR INTERNAL COMPONENTS.
