GENERAL SETUP
Allow your unpacked unit to acclimate to room temperature for at least 30 minutes as noted in step 1 below.
Refer to the diagram on the previous page for names and locations of controls mentioned below.
1. Keep the unit away from the existing register's airstream and allow the unit to acclimate to room temperature for 30 minutes before
applying power.
2. Insert the small end of the power supply cord into the receptacle on the Equalizer Ez8 Register Booster™Plug the power supply
into your 110V outlet. Additional length can be added to the power supply cord using a 2.1mm ID / 5.5mm OD low-voltage extension
cord. Unit can be wall-mounted with the purchase of our ****** wall mounting kit.
3. Prior to making the initial settings, do not place the unit over the supply register while the forced air system is running. Allow at
least 5 minutes following the end of the forced air cycle for temperatures near the supply register to stabilize.
4. For wall-mounted units, start with the mode set to “off”. Press the mode button until no mode indication lights are lit. Allow at
least 10 minutes after the forced air system ends before entering the temperature-sensitive mode of your choosing.
5. Factory default setting for operation mode is “Auto”. Factory default setting for fan speed is speed #3 (of 8). Factory default
setting for system recovery (on/off delay) is short (knob fully counter-clockwise). This is the recommended configuration, but further
adjustments can be made per the instructions below.
6. Pressing the mode button iterates through the modes as follows: Auto, Fan, Heat, Cool, Off, Auto, Fan, etc…
7. Both mode and fan speed selections will be maintained upon power loss. So the Equalizer Ez8 Register Booster™is suitable for
applications involving timers, switched outlets, or other devices that regulate the power to the unit.
AUTO MODE
When the orange Auto ( ) mode indication light is lit, the Equalizer Ez8 Register Booster™will automatically turn the booster fan on
when either the warm air from the furnace or the cool air from the air conditioner is detected. It will turn off once it no longer senses
the presence of adequately heated or cooled air from the register. This mode requires no seasonal adjustments.
1. After following the general setup procedures above, ensure the orange Auto mode indication light is lit.
2. In Auto mode, the adjustment knob sets the ‘recovery’ rate of the booster.
a.With the knob fully counter-clockwise, the booster fan has a ‘fast’ recovery time. The booster will start after 8-15 seconds
of forced air system operation. The booster will generally stop within 6-20 seconds of the end of the forced air cycle. A fast
recovery time achieves a closer synchronization with the forced air system.
b. Turning the knob clockwise slows the recovery time. The booster will wait additional time after the start / end of the forced
air cycle before turning the fan on/off. With the knob fully clockwise, the recovery time will be approximately 120 seconds.
A slower recovery time will delay the start of the booster fan, allowing the furnace or air conditioner to achieve a
higher/lower temperature before the airflow boosting begins. It will also run the booster fan for a longer period after the
forced air cycle has ended, thereby recovering some of the latent conditioned air in the ductwork and delivering it to the
room.
3. Once the forced air system starts, observe the Equalizer Ez8 Register Booster™for the behavior described above.
a. If the fan does not start, ensure that the adjustment knob is fully counter clockwise.
b. If the fan runs intermittently during the forced air cycle, consider another operating mode.
c. If the fan runs intermittently in between forced air cycles, increase the recovery setting or consider another operating mode.
d. If the fan seems to be operating in the opposite fashion as described above (booster fan on when forced air is off, booster
fan off when forced air system is on), set the unit to Off mode. Allow 5-10 minutes after the end of the forced air cycle. Do
not adjust whole home thermostat, but rather allow the forced air cycle to start/end naturally. After this waiting period, return
to Auto mode to reset the logic.
FAN MODE
When the green Fan ( ▌) mode indication light is lit, the Equalizer Ez8 Register Booster™will run the fan continuously regardless of
the temperature conditions. This mode is appropriate for general ventilation applications as well as forced air applications in which
the air handler’s blower is always running (‘fan’ set to ‘on’ rather than ‘auto’ at the system’s thermostat).
HEAT MODE
When the red Heat (▲) mode indication light is lit, the Equalizer Ez8 Register Booster™will automatically turn the booster fan on
when the warm air from the supply register rises above the temperature setpoint. It will turn off once the temperature falls below the
setpoint. This mode is recommended for ‘heating’ season if Auto Mode is not appropriate for your application. This is also the proper
mode for temperature-dependent equipment enclosure ventilation. With x2 1U rackmount blank panels, the Equalizer Ez8 Register
Booster™ will occupy 6U of a standard 19” equipment rack; or with a properly sized opening, the booster can mount directly to the
exterior of any solid enclosure. See ****** wall mounting kit instructions for more information.

1. After following the general setup procedures above, ensure the red Heat mode indication light is lit.
2. In Heat mode, the adjustment knob regulates the temperature setpoint of the booster.
a. With the knob fully counter -clockwise, this represents a setpoint temperature of approx. 65F (18C).
b. With the knob in the center of the range, this represents a setpoint temperature of approx. 85F (29C).
c. Moving the knob from left to right increases the temperature setpoint.
d. A higher temperature setting will allow more time to elapse after the start of the furnace cycle before the booster fan turns
on. The booster fan will turn off sooner after the end of the furnace cycle.
e. A lower temperature setting will start the booster fan sooner after the start of the furnace cycle, but will also continue to
run the booster fan for several minutes after the furnace cycle has ended.
3. Start with the adjustment knob fully counter-clockwise.
4. After the start of the furnace cycle, allow 30-45 seconds of central blower operation to occur before proceeding to the next step.
5. Slowly turn the knob clockwise until the booster fan turns on. This is the setpoint adjustment.
6. Once the next forced air system starts, observe the Equalizer Ez8 Register Booster™for the behavior described above
a. If the booster fan does not start soon enough or at all, move the adjustment knob counter-clockwise to choose a lower
setpoint.
b. If the booster fan runs more than 5 minutes after the furnace cycle has ended, consider a higher setpoint.
c. Observe the next furnace cycle to confirm your adjustments have been satisfactory. Repeat steps a-c as necessary.
d. In forced-air systems which have the thermostat’s fan setting to “on” rather than “auto,” the central blower is always on.
The booster fan will generally have an extended run-time in systems such as this, or may require a warmer setpoint.
COOL MODE
When the blue Cool (▼) mode indication light is lit, the Equalizer Ez8 Register Booster™will automatically turn the booster fan on
when the cool air from the supply register falls below the temperature setpoint. It will turn off once the temperature rises above the
setpoint. This mode is recommended for ‘cooling’ season if Auto Mode is not appropriate for your application.
1. After following the general setup procedures above, ensure the blue Cool mode indication light is lit.
2. In Cool mode, the adjustment knob regulates the temperature setpoint of the booster.
a. With the knob fully clockwise, this represents a setpoint temperature of approx. 60F (16C).
b. With the knob in the center of the range, this represents a setpoint temperature of approx. 70F (25C).
c. Moving the knob from right to left decreases the temperature setpoint.
d. A lower temperature setting will allow more time to elapse after the start of the air conditioning cycle before the booster
fan turns on. The booster fan will turn off sooner after the end of the A/C cycle.
e. A higher temperature setting will start the booster fan sooner after the start of the air conditioning cycle, but will also
continue to run the booster fan for several minutes after the A/C cycle has ended.
3. Start with the adjustment knob fully clockwise.
4. After the start of the air conditioning cycle, allow 30-45 seconds of central blower operation before proceeding to the next step.
5. Slowly turn the knob counter-clockwise until the booster fan turns on. This is the setpoint adjustment.
6. Once the next forced air system starts, observe the Equalizer Ez8 Register Booster™for the behavior described above
a. If the booster fan does not start soon enough or at all, move the adjustment knob clockwise to choose a higher setpoint.
b. If the booster fan runs more than 5 minutes after the air conditioning cycle has ended, consider a lower setpoint.
c. Observe the next furnace cycle to confirm your adjustments have been satisfactory. Repeat steps a-c as necessary.
d. In forced-air systems which have the thermostat’s fan setting to “on” rather than “auto,” the central blower is always on.
The booster fan will generally have an extended run-time in systems such as this, or may require a cooler setpoint.
GENERAL NOTE ABOUT FAN SPEEDS
1. The Equalizer Ez8 Register Booster™is factory-configured for speed #3. This is a typical setting for most applications.
2. There are 8 fan speed settings that are incremented by momentarily pressing the speed button.
3. Pressing the speed button iterates through the fan speeds as follows: 4,5,6,7,8,1,2,3,4,5,6,7,8,1,2, etc…
4. Fan speed is displayed temporarily. The speed indication does not persist after confirming the speed to the User.
5. The speed can be adjusted in any operating mode except “Off”. Adjusting the speed will not turn the fan on.
6. The speed can be adjusted while the fan is operating.
7. To display the current fan speed without changing the setting, press and hold the speed button for more than 2 seconds.
8. Adjusting the fan speed, like all air-moving equipment, involves a trade-off between noise and performance.
a. A speed that is too low will be quieter, but may not deliver adequate airflow.
b. A speed that is too high will not only be louder, but may ‘over-condition’ the space by drawing too much air from the
branch duct.
c. The Equalizer Ez8 Register Booster™should always be operated at the lowest speed capable of delivering a noticeable
improvement in room comfort after several days of initial operation. This will ensure that the selected fan speed is
appropriate for the application while emitting the least amount of noise from the fan.
