1. DESCRIPTION OF YOUR UNIT AND IT’S BENEFITS
Since the energy crisis in the early 1970’s, governments and the building
community have sponsored many programs and changed codes to foster reduced
energy requirements and create energy costs savings for the consumers. Each of
these efforts, while improving the energy efciency of our homes and buildings,
has resulted in the loss of natural ventilation and trapped excess humidity and
pollutants indoors.
It is due to this air tightness that your dwelling or place of business will incur
humidity from everyday activities such as cooking, bathing, washing, indoor
drying of clothes and normal breathing and perspiration. Pollutants such as
smoke from cooking and replaces or wood burning stoves, dust, pollens,
airborne viruses and molds and radon gas can also be trapped in your residence.
Your SUMMERAIRE Heat Recovery Ventilator (HRV) is designed to resolve
these problems by providing fresh air into your home or building while
exhausting an equal amount of stale, humid air. This “exchange” process enables
you to remove undesirable pollutants continuously as well as excess humidity
during the heating season. The advantage offered by your HRV is that it transfers
the energy from your exhausted (inside conditioned air) to temper the incoming
fresh air system.

2. SUGGESTED OPERATING INSTRUCTIONS
Anytime the HRV is powered on allow 20 seconds for the main
control to reset prior to making any operational selections.
Heating Season
Turn HRV ON, fan speed will cycle to previously select mode of operation.
Continuous low speed ventilation is recommended to ensure that fresh air is
available to building occupants.
If your home feels too humid or if you have water condensation on the windows,
rotate the built-in dehumidistat Dial (left side of HRV). Set dehumidistat control
between 30-40% humidity.
If your home feels to dry: rotate dehumidistat Dial (left side of HRV) slowly in
a COUNTER-CLOCKWISE direction in 5 point increments and allow HRV to
run in this position for 24 hours. If symptom continues, repeat this step. Also, if
there is a humidier installed, check to make sure it is working properly.
If a higher rate of continuous ventilation is desired: Press the SELECT button
(located at left hand side of HRV) once to change to the next run speed.
If HRV continuous ventilation is not desired (not recommended), press the
SELECT button until LED at AUTO/OFF is illuminated. HRV will not run
unless a wall control is activated. Remote Touch Pad will activate 20/40/60
minutes of high-speed ventilation and then the HRV will return to AUTO/OFF.
Dehumidistat activation results in high-speed ventilation until humidity level of
indoor air is less than the dehumidistat setting, then the HRV will then return to
AUTO/OFF.
Note: If your house is too dry, it’s best to install a humidier rather than to turn
the HRV off.

Air Conditioning Season
Continuous ventilation is recommended when the house is being heated or
cooled, anytime windows are closed. For summertime operation of the HRV,
turn the dehumidistat setting counter clockwise to off (80%), set run speed to
LOW. Changing the stale indoor air with fresh outdoor air is just as important in
the cooling season as it is in the heating season!
If no HRV ventilation is desired (not recommended): Press SELECT button until
LED at AUTO/OFF is illuminated. HRV will not run unless a Remote Touch Pad
is activated. Wall control activation results in 20/40/60 minutes of high-speed
ventilation. After 20/40/60 cycle the HRV will return to AUTO/OFF. Continuous
low speed HRV ventilation is recommended throughout the year.
REMOTE CONTROL DEVICES
SCOUT (Remotely Located)
Fan speed selection, Auto/Off and system Off maybe selected. The HRV defrost
cycle is also displayed when active.
20/40/60 minute Touch Pad;
Touch Pads switch the HRV to high speed for 20/40 or 60 minutes. Each touch
pad station will illuminate while the HRV is running at high speed.

3. HOW TO OPERATE UNIT AND RELATED CONTROLS
Anytime the HRV is powered on allow 20 seconds for the main
control to reset prior to making any operational selections.
To realize the full benet of your HRV, it should be operated continuously to
control humidity and supply fresh outdoor air.
Continuous ventilation of your home is very important, and as the need arises
to introduce higher levels of ventilation, you can select increased fan speeds at
the HRV, or if installed, at remote devices such as; TOUCH PAD TIMERS, or
SCOUT, WATCHMAN or SENTINEL controls.
This section reviews the basic operation of your HRV and related controls to
maximize your home comfort.
All units are equipped with a Safety door switch, built in On/Off switch,
Variable Speed Fan control, Dehumidistat control and have automatic damper
defrost control, which is preset at the factory.

On/Off Switch
The ON/OFF switch supplies and disconnects power to the HRV control board.
When positioned in the ON position, this switch will illuminate. The switch will
not illuminate if the power supply is disconnected or the switch is turned to the
OFF position.
Option Select Button
By depressing the SELECT button momentarily, you can select low, medium or
high ventilation fan speeds, as well as the AUTO/OFF or SYSTEM OFF modes.
The selection will be indicated by the illumination of the respective LED on the
HRV display panel.
Auto/Off
When this mode of operation is selected, the HRV ventilator fan will be turned
off until activated by the internal dehumidistat or an optional external control
such as a Wall Mount Dehumidistat, Wall Switch, Touch Pad Timer, Scout,
Watchman or Sentinel control. This selection is displayed by the continuous
illumination of the Auto/Off LED on the HRV, SCOUT, WATCHMAN and
SENTINEL controls. When the fan is activated automatically or manually at
a Touch Pad, it will be indicated by the ashing On and Off of the High-speed
indicator on the control panels.
High Speed Flashing
When the internal dehumidistat or an external control has activated the HRV
to high speed, the High Speed LED light will illuminate and ash. If you have
already selected one of the ventilation speeds as discussed in the previous
section “Option Select Button”, and the High Speed has been activated, then
you will see both the continuously lit LED for the fan speed selection and the
high speed LED ashing. Once the device initiating the high speed cycle has
been satised, the HRV control fan will reset to the pre-selected mode and the
ashing High Speed LED will turn off.
Summer / Winter Switch
This switch must be positioned in the summer position when the optional
summer core is installed in the HRV. This will cause the HRV to shut down
should the air temperature entering the HRV fall below -15°C (5°F). This
prevents permanent damage to the core. Position this switch to winter when
the winter core is used to ensure correct operation during colder periods.
8
Status Display Indicator Lights
The LED indicator lights illuminate to indicate the current active mode of
operation. The defrost indicator will illuminate when the HRV cycles into the
automatic defrost cycle; this occurs at a predetermined cycle time whenever the
outside air stream entering the HRV is colder than -3°C (26°F).
Defrost Cycle
Your HRV is equipped with electronically controlled damper defrost. When
the outdoor temperature entering the HRV drops below -3°C (26°F) the defrost
timer is activated. After approximately 30 minutes of ventilation (during which
time the core unit may experience some frost build-up during the heat recovery
process) the timer activates the damper door mechanism which closes off the
fresh air supply port, opens the defrost port and the defrost led illuminates.
After approximately 5 minutes of defrosting the recovery core, the damper door
reverses direction and reopens the fresh air port and the unit returns to normal
operation and the defrost led turns off. The cycle will repeat itself until the
outdoor temperature entering the HRV rises above -3°C (26°F).
Internal Dehumidistat
This control regulates the desired amount of humidity in your home during
the heating season. By simply adjusting the rotary knob on the HRV, varied
levels of relative humidity can be selected.During the colder months of winter,
the Internal Dehumidistat should be set to an industry recommended comfort
range of 30% to 40% relative humidity (R.H.). If the house feels too dry, then
adjust the setting higher and if too damp, then adjust the setting lower.During
these colder months, the Internal Dehumidistat should be set lower if excessive
moisture develops on the windows. In the warmer months, when the outdoor
humidity is equal to or greater than the indoor humidity, the dehumidistat should
be turned to the OFF position.

OPTIONAL CONTROLS
20 Minute Remote Timer Touch Pad
Model ECPBT
This 20-Minute Touch Pad MUST be connected to the “CT”
terminals on the HRV exterior. This control will not function if
connected PBT connection points. Install using 18/2-thermostat
wire. Maximum number of ECPBT controls per HRV is eight.
Maximum cumulative lead length is 2000 lineal feet. Touch
pads are typically installed where 20 minutes of high speed
ventilation may be desired.
Once activated by a momentary push, approximately three
seconds, of the SELECT button on the Touch Pad the HRV
is switched to high speed ventilation and the Touch Pad LED
will illuminate. The HRV will reset to the previously selected
mode of operation once the 20 minutes have expired. To cancel
the selection, depress the SELECT button on the 20-minute
Touch Pad for a minimum of 3 seconds. The selection can
also be cancelled at any other optional control by momentarily
depressing the SELECT button.
NOTE: This control will not respond while a crank timer is
operational.

Remote Timer Touch Pad - Model PBT
Timer Touch Pads are typically installed in any room
where 20/40 or 60 minutes of high-speed ventilation
may be desired, i.e. bathrooms and/or kitchens. Once
activated by a momentary push, these buttons illuminate
to indicate high speed activation. If more than one touch
pad is installed in the system then all will illuminate upon
activation until the timed sequence has expired. To cancel
a selection simply continue to push the select button
until it turns off. The display LEDS on the touch pad will
illuminate to represent the time remaining.
Wall Mount Dehumidistat - Model SRDEH
This control is typically installed in an area of the home
where humidity may require automatic monitoring. This
could be a central location (i.e. near furnace thermostat)
or in a specic room (i.e. kitchen, laundry etc.).
Scout Control
This control is detachable from the HRV to provide a
remote control operation of the HRV. Once removed from
the HRV one can only turn the power off at the HRV. By
positioning the Scout remotely to the HRV, you can adjust
fans speeds, select auto/off, intermittent or turn the main
HRV control Off. When the HRV has been turned off
using the Scout, power still remains on at the HRV on/off
switch however all external controls will not function.
Intermittent- In this mode the ventilation fan will run for
20 minutes and turns off for 40 minutes. This cycle will
continue until cancelled. External devices are active.
