11. BALANCING THE UNIT
(RNC 1.5, RNC 2.0 & RNC 2.0ES ONLY)
TOOLS REQUIRED TO
BALANCE THE HRV/ERV
• A Magnehelic gauge capable of
measuring 0 to 2.0 inch of water (0 to
500 Pa) and two (2) plastic hoses.
• A balancing reference chart located
on the HRV/ERV access door panel.
CONSIDERATION WHEN
BALANCING THE HRV/ERV
• Seal all the unit ductwork with tape.
Close all windows and doors.
• Insure all exhaust devices such as range
hood, dryer and bathroom fans are OFF.
• Make sure that all filters are clean
and that there is no obstruction in
ductwork
• Make sure that the forced air system
blower is “ON” when connected to an
existing forced air system ductwork.
• If it is a direct duct system installation
ensure forced air system blower is
“OFF”.
USING THE DUOTROL

IMPORTANT:
Insure the HRV/ERV has
completed the defrost sequence. That
the dehumidistat is deactivated by
turning the round dial to the “OFF”
position, the Range is” NORMAL”, the
mode is “CONT” and the Cycle per Hour
is set at “0/0”.
NOTE: The unit is considered balanced
even if there is a difference of ±10 cfm
(or ± 5 l/s or 17 m³/h) between the two
air flows
DUOTROL™ BALANCING SYSTEM PROCEDURES
Step 1: Place the Magnehelic gauge on a level surface and
adjust the needle to zero.
Step 2: Connect the two (2) plastic hoses to the gauge on
the HIGH & LOW pressure connections.
Step 3:
Once the total ventilation requirements are
determined, you can start balancing the HRV/ERV.
(Refer to 1. Ventilation Requirements)
Step 4:
Remove the (4) four nylon knock out seals located on
the HRV/ERV access door. ( Ref fig 11.1 )

Note: If the gauge needle drops below zero, reverse the
plastic
hose connections.
Step 6:
Press the
(+)
and
(–)
buttons on the Duotrol™
simultaneously until you see the yellow light. Once the
indicator light turns yellow and the unit goes to high speed
you are in balancing mode. When in balancing mode the
selector switch on the Duotrol™ becomes the motor selector
switch. INTER (Right Motor = Stale Airflow), CONT (Both
Motors) and OFF (Left Motor = Fresh Airflow)
Step 7:
To adjust the
(fresh air)
, select the «OFF» position
on the Duotrol™. Ensure the plastic hoses from the gauge
are connected to the HIGH & LOW balancing pressure taps
on the fresh airflow side located on the HRV/ERV access
door. ( Ref Fig 11.2 ). To adjust the airflow rates, press the
(–)
button to decrease or press the
(+)
button to increase
the airflow rates until you reach the calculated fresh airflow
requirements.
Step 8: To adjust the (stale air) select the «INTER» position
on the Duotrol™. Ensure the plastic hoses from the gauge
are connected to the HIGH & LOW balancing pressure taps on
the stale air side located on the HRV/ERV access door. (
Ref
Fig 11.2
) To adjust the airflow rates, press the (–) button to
decrease or press the (+) button to increase the airflow rates
until you reach the calculated stale airflow requirements.
Step 9: Once this is completed, you have balanced the
airflow rates of your HRV/ERV. To exit the balancing mode
you must press (+) and (–) buttons on the Duotrol™
simultaneously until solid green LED appears then release.
The indicator light will turn green to indicate normal operation
mode. Seal the (4) four balancing pressure taps with the
nylon knock out seals removed in Step 4.
Step 10: Mark down the balanced air flow rates information
on a label including in the kit. Apply the label to the HRV/ERV
access door for future reference (e.g. date, balance airflow
rate, your name, phone number and business address).
Note:
Once the HRV/ERV is balanced, switch to «CONT» on
the Duotrol™ By using
(+)
and
(–)
buttons you can set the
continuous speed.
