APPLICATION WARNING
It is always important to assess how the
operation of any Heat Recovery Ventilator
(HRV) may interact with vented combustion
equipment (i.e. gas furnaces, oil furnaces,
wood stoves, replaces. etc.)
Never install an HRV in a situation where
it’s normal operation, lack of operation, or
partial failure may result in the back drafting
on vented combustion equipment such as
water heaters, furnaces and replaces
DO NOT ATTEMPT INSTALLING THIS HRV WITHOUT FIRST

1. OPTIONAL CONTROLS
20 Minute Remote Timer Touch Pad
Model ECPBT
This control is polarized. If wired incorrectly a fault will be
indicated at the HRV LED by a ashing RED light.
Once activated by a momentary push 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 (and hold for 3-4
seconds) the SELECT button on the 20-minute Touch Pad.
This 20-Minute Touch Pad MUST be connected to the “PTE”
and “GRD” terminals on the HRV exterior.
NOTE: The connections to this control are polarized. Be sure to
connect “B” to BLACK and “W” to WHITE at the control.
Connect WHITE to “PTE” and BLACK to “GRD” at the HRV.
INSTALL USING 18/2 THERMOSTAT WIRE.
MAXIMUM NUMBER OF ECPBT CONTROLS
PER HRV IS SIX.
MAXIMUM CUMULATIVE LEAD LENGTH IS
2000 LINEAR FEET.
NOTE: This control will not respond while a crank timer is
operational.

Wall Mount Remote Control
Model SelectAire
This is a non-polarized control
This is an optional control device that provides the following
options; System Off, Auto/Off, Intermittent, Fan Speed Low,
Medium or High.
This control is connected to the Main HRV terminal block using
18/2 thermostat wire.
Up to two (2) SelectAire controls can be installed on one HRV.
Refer to wiring diagram for connection method.
Wall Mount Dehumidistat
Model SRDEH
This is a non-polarized control
This is an optional device providing indoor relative humidity
control. Activation occurs when the indoor humidity is higher than
the selected level. The HRV will function at high-speed fan until
the indoor humidity is lower than the set point on the control. The
HRV control will then default to the pre-selected mode.
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 specic
room (i.e. kitchen, laundry etc.).
Connect to HRV using 18/2 thermostat wire.
Connect one lead to “DEH” and the second to “GRD” at the
HRV. Refer to Wiring Diagram.

2. MODEL SELECT SWITCH
Refer to drawing g. 1.
The model select switch must be set to the HRV model it is installed into to ensure proper unit
operation.
This switch is factory set.
Failure to ensure the switches are set as required will result in improper operation.
The model select switch is a 3-position dipswitch located on the exposed side of the control
board when the electrical cover is removed.
Switch positions are:
The above switch positions apply when the orange terminal connection strip is located in the
upper left corner of the HRV (when facing the unit from the door side). Reverse the switch
positions if the orange terminal strip is in the lower right side on the HRV.

3. FAN CURVE SELECTION
HRV model SHRV150DM supports two (2) eld selectable fan curves:
Fan curve switch position “A” and switch position “B” (factory set).
Note that switch position “C” is unused and will provide fan curve “B” if selected.
Fan curves are selected at the HRV control board.
To select an alternate fan curve;
1. Refer to the chart below to determine the desired fan curve.
2. Disconnect supply power to HRV.
3. Remove the HRV front door and electrical control box cover.
4. Locate the fan curve slide switch, which is located on the exposed surface
of the PCB control.
5. Select either fan curve A or B by sliding the switch up or down to the desired position.
6. Reassemble and reconnect power.

4. SELECTING A LOCATION
Typically the HRV is located in the mechanical room with close
proximity to an outside wall. Other installation locations are
acceptable provided that the ambient air temperature does not
fall below freezing. This is to prevent the condensate drain lines
from freezing.
5. MOUNTING THE HRV
The ProVentor series of HRVs may be rotated 180 degrees to permit the connection of the
outside air streams to either the left or right hand side. They are factory supplied to be
nstalled with the cold air support streams on the left. To install this HRV in the reverse
conguration simply remove the plastic drain hole plugs from the top of the cabinet and insert
into the drain holes in the bottom.
Included with the HRV are four (4) laminated rubber hanging straps. These are to be secured
at each of the four corners of the HRV using the screws provided. The other ends of the straps
should be secured to the oor joists using large head screws. To ensure proper condensate
ow, HRV must be installed level in both directions.
NOTE: The cold supply duct collar is supplied loose. Once the orientation of the HRV is
determined, install this collar using the four screws provided. This collar must be installed
with its orientation arrows on the side of the collar pointing up.
HRV duct connections are 6”

6. CONDENSATE DRAIN HOSE INSTALLATION
Two (2) drain spigot assemblies are provided. These are to be installed through the drain pan holes
provided. Install the spigot through the openings and secure in place by installing the nylon washer
and nut on the outside of the cabinet. Ensure that the drain holes that are not used are plugged with
the drain plugs installed in the cabinet. Once installed, attach 1/2” plastic tubing (not supplied) to the
spigots. Create a trap by forming a loop in the tubing. This will prevent the cross contamination of
the air streams through the tubing. Ensure that the condensate drain tubing is not exposed to freezing
temperatures. Typically the drain line is connected into a oor drain, sink or stand pipe.
