Thank you for buying a Broan unit!
We have prepared this User Guide especially for you. Please read it carefully to ensure you obtain full benefit from your ERV.
Please take note that this manual uses the following symbols to emphasize particular information:
CAUTION
Make sure at all times that the outdoor intake and exhaust hoods are free from any snow during the winter season. It is
important to check your unit during a big snow storm, so it doesn’t draw in any snow. If this is the case, please operate the
unit in recirculation mode (if available), or turn it OFF for a few hours.
Do not use your unit during construction or renovation of your house or when sanding drywall.This type of dust may damage
your system.
Since the electronic control system of the unit is incorporated with a microprocessor, it may not operate correctly because of
external noise or very short power failure. If this happens, unplug the unit and wait approximately 10 seconds. Then, plug the
unit in again.
When leaving the house for a long period of time (more than two weeks), a responsible person should regularly check if the
unit operates adequately.
If the ductwork runs through an unconditioned space (e.g.: attic), the unit must operate continuously except when performing
maintenance and/or repair. Also, the ambient temperature of the house should never drop below 65°F.
At least once a year, the unit mechanical and electronic parts should be inspected by qualified service personnel.

When the outdoor temperature is below 14°F, recovery of energy creates frost in the core.
To maintain its proper operation, the unit is programmed to defrost the energy recovery core.
For ERV100S model, during the defrost cycle, the unit keeps the same speed but stops to supply fresh air.
For ERV100SP model, during the defrost cycle, the dampers close but the unit speed can be set on high or low, according to your needs.
See point 2.4 for more details.
After defrosting, the unit returns to the operating mode selected by the user.

2.CONTROLS
2.1 ERV100SP BOOTING SEQUENCE
VC0152
A
The unit booting sequence is similar to a personal computer booting sequence.
Each time the unit is plugged after being unplugged, or after a power failure, the unit will perform a booting sequence before starting
to operate.
During the booting sequence, the LED located on the unit door (Ain illustration below) will be OFF for 3 seconds, and then will
turn RED for the rest of the booting sequence (approximately 30 seconds). During this RED light phase, the unit is checking and
resetting the motorized damper position.
Once the motorized damper position completely set, the booting sequence is done; the color of the LED will show on which defrost
cycle the unit is set.
NOTE: No command will be taken until the unit is fully booted.
2.2 ERV100S BOOTING SEQUENCE
The unit booting sequence is similar to a personal computer booting sequence.
Each time the unit is plugged after being unplugged, or after a power failure, the unit will
perform a booting sequence before starting to operate.
During the booting sequence, the integrated control LED located on the unit door (Ain
illustration at right) will light up and remain GREEN or AMBER for 3 seconds, and will
then shut off*; the booting sequence is done.
* or will light the color of the previous mode to show the unit resume to it, if the unit is
controlled by its integrated control.
NOTE: No command will be taken until the unit is fully booted.
If a problem occurs during the unit operation, or if the unit turns in Protection mode*, its integrated control LED (A) will blink. The
color and pattern of the blinking light depends on the type of error detected, or if running in Protection mode. Refer to the sticker on
the unit and to Section 4Troubleshooting for further details.
* All units are equipped with an electronic supplemental protection, called Coldshield™ Protection, to stop air distribution in dwelling
if air distribution temperature drops below freezing point, due to abnormal conditions.
2.3 BLINKING LED

2.CONTROLS (CONT’D)
After the booting sequence is done, the LED (A) will light and stay lit to show in which defrost cycle the unit is set. Use the push
button (B) to change the defrost cycle of the unit (see table below).
2.4 ERV100SP INTEGRATED DEFROST CONTROL
VC0152
AB
According to your needs, there are 3 defrost cycles available:
STANDARD: This is the factory set defrost cycle. This mode is the most efficient used to suit HVI and ENERGY STAR®
performance. When needed, the unit will perform defrost cycle on high speed.
PLUS: This mode has been created for people who live in cold region (outdoor temperature -17°F and lower). This setting
makes the unit perform defrost cycle on high speed for a longer period of time.
DISCRETION: When needed, the defrost cycle will be performed on the same speed than the unit ventilation speed. This means
that if the unit is set on high speed, the defrost cycle will be done on high speed, but if the unit is set on low speed,
the defrost cycle will be done on low speed.
NOTE:There is a 15-minute delay for the new defrost cycle choice
to be kept in memory; if a power failure occurs during this
time delay, when the power returns, the unit resume to its
previous setting.
LED COLOR RESULTS
AMBER UNIT IS ON LOW SPEED
GREEN UNIT IS ON HIGH SPEED
NOLIGHT UNIT IS OFF OR CONTROLLED BY AMAIN CONTROL
Use the push button (B) to control the unit. The LED (A) will then
shows on which mode the unit is in. Refer to table at right.
NOTE: When using main control, the integrated control
must be turned off (no light from LED).
2.5 ERV100S UNIT INTEGRATED CONTROL
2.6 SETTING EXTENDED DEFROST FOR ERV100S UNIT
These units are factory set to normal defrost. In cold region (outdoor temperature -17°F and
lower), it may be necessary to setup extended defrost. During the first 3 seconds of booting
sequence, the integrated control LED shows the current defrost mode (refer to table at right).
LED COLOR DEFROST MODE
GREEN NORMAL
AMBER EXTENDED
Within the first 3 seconds of booting sequence, press on push button until the LED starts to blink, then release the push button; the
LED will blink AMBER 5 times. After that, the LED will shut off, then turn RED (the unit returns in its booting sequence).

2.7 MAIN AND AUXILIARY CONTROLS
The ERV100SP unit must be controlled by a main control. For more convenience, the ERV100S unit can also be controlled using
an optional main control. Only one main control can be connected per unit.
NOTES:1. The integrated control must be turned OFF on ERV100S model to use a main control.
2. If an optional auxiliary control is used, if activated, the operation of this auxiliary control will override the optional main
control operation.
