HR150, 200; ER150, 200 Perfect Window™ Fresh Air Ventilation Systems 68-0171EF—01

GETTING

STARTED

The Fresh Air Ventilation System is designed to

supply fresh air and exhaust stale air. The system

draws fresh outdoor air through the ventilator for

distribution throughout the house.

Heat Recovery Ventilator

Stale air is exhausted through the ventilator and to

the outdoors. Heat is transferred from one airstream

to the other as the air passes through the opposite

sides of the heat transfer core. See Fig. 1.

Energy Recovery Ventilator

Stale air is exhausted through the ventilator and to

the outdoors. Heat and moisture is transferred from

one airstream to the other as the air passes through

the opposite sides of the energy transfer core.

See Fig. 2 and 3.

Planning the Installation

Failure to comply with these requirements will result in voided warranty, improper installation, and

service callbacks.

Sizing

ASHRAE 62.2

There are several methods that can provide

satisfactory results for sizing a ventilator to provide

adequate ventilation for a home. There is a new

residential ventilation standard, ASHRAE 62.2, that

suggests the following:

7.5 CFM per person (count people as 1 per •

bedroom plus 1) plus 1 CFM per 100 sq. ft.

Example:

2200 sq. ft. house with 4 bedrooms

= (7.5 CFM x (4 bedrooms + 1)) + (1 CFM x (2200 sq. ft. / 100))

= (7.5 x 5) + (2200 / 100)

= 37.5 + 22

= 59.5 CFM

In this case 60 CFM continuous would provide

satisfactory ventilation for this home.

ASHRAE 62.1

Some regions still use the previous standard, ASHRAE

62.1, as the code for ventilation in their region.

The ASHRAE Standard 62.1 Ventilation for Acceptable

Indoor Air Quality suggests the following:

.35 air changes per hour (ach) but not less than 15 •

cfm per person for living areas = house size (sq ft)

x ceiling height (ft) / 60 (min) x.35 (ach)

Example:

= 2000 sq ft x 8 ft / 60 min x .35 ach = 93 cfm

50 cfm intermittent or 20 cfm continuous capacity •

for bathrooms

Example:

50 cfm intermittent x 3 bathrooms = 150 cfm

20 cfm continuous x 3 bathrooms = 60 cfm

100 cfm intermittent or 25 cfm continuous capacity •

for kitchens

Example:

100 cfm intermittent x 1 kitchen = 100 cfm

25 cfm continuous x 1 kitchen = 25 cfm

Option 1: Fresh Air Ventilation System provides

continuous fresh air supply of 93 cfm, and intermittent

capacity for bathrooms of 150 cfm. A separate 100

cfm exhaust fan is used for the range hood.

Supply air ﬂow required = 93 cfm

Exhaust air ﬂow required = 150 cfm

Any Honeywell ventilation unit provides suitable

ventilation capacity. See Fig. 22.

Option 2: Fresh Air Ventilation System provides

continuous 93 cfm fresh air supply, 150 cfm

intermittent exhaust capacity for bathrooms and

continuous 50 cfm kitchen ventilation.

Supply air ﬂow required = 93 cfm

Exhaust air ﬂow required = 200 cfm

Honeywell HR200/ER200 have the exhaust capacity

required to meet the ventilation needs of this

application. See Fig. 22.

HR150, 200; ER150, 200 Perfect Window™ Fresh Air Ventilation Systems 68-0171EF—01

GETTING

STARTED

Mounting Position and Location

The HR150/ER150 and HR200/ER200 can be

suspended from exposed ceiling joists, ceiling surface

or ﬂoor mounted. (Level ventilator so drains function

correctly.)

NOTE: ER150C and ER200C are speciﬁcally designed

for installations in unconditioned spaces such as

attics and garages in regions where the outdoor

temperature does not drop below freezing. (These

units are not equipped with drain kits.)

Locate fresh air intake 6 ft (2m) or more from stale •

air exhaust to prevent exhaust air from re-entering.

Locate ventilator where length of ducting required •

is minimal.

Install HR150/ER150 and HR200/ER200 in a

conditioned space using these guidelines:

Pipe drain line (ER150C and ER200C do not have •

drain kits) from the ventilator to a drain.

Use an existing electrical outlet with appropriate •

current rating (or install one) close to ventilator

power cord.

Allow space for drain line by placing the ventilator •

at least 10 in. (254 mm) off the ﬂoor.

For access and removal of ventilator core, allow at •

least 25 in. (635 mm) of open space in front of unit.

Ducting

Ducting between the ventilator and the outdoors must

be insulated and have a continuous air vapor barrier.

See Fig. 4.

IMPORTANT

All ducting to the outdoors must be terminated above

anticipated snow lines and be ﬁtted with a weather cap

that incorporates bird screening.

HR150, 200; ER150, 200 Perfect Window™ Fresh Air Ventilation Systems 68-0171EF—01

Sealing insulated duct terminations.Fig. 4.

GETTING

STARTED

Design and installation of ductwork must be according to standard HVAC practice to deliver required quantities

of fresh air to temperature-controlled space and exhaust equivalent quantities of room air to the outside.

Keep intake and exhaust duct runs as short as possible with few bends or elbows.

Keep duct sizes as large as possible throughout the installation.•

Use a 6 in. diameter round duct for all connections to and from the ventilator.•

Separate outside intake and exhaust vents by at least 6 ft (2m).•

NOTES: Do not locate the fresh air vent where it blows directly onto occupants or the thermostat.

Do not locate the fresh air intake close to known sources of pollutants such as automobile exhaust, a

dryer vent or chimney smoke.

Ducting the supply outlet and/or the exhaust inlet of the ventilator to the return air plenum of the air handler •

is an excellent way to distribute fresh air and exhaust stale air from all parts of the house, while reducing

installation costs. When choosing this method, balance the ventilator when the air handler is running and

interlock the ventilator so that it can run only when the air handler runs. See Fig. 6. An alternate method is to

balance the ventilator when the air handler is not running and let the ventilator run whether the air handler is

running or not, see Fig. 5. An independent installation is shown in Fig. 7.

NOTE: When the home is occupied, continuous operation of the ventilator is recommended. When the furnace air handler

operates, fresh air is distributed through the heating/air conditioning supply registers. When the air handler is off,

fresh air is delivered through both supplies and returns.

An electrical interlock or an automatically powered damper must be used to prevent unwanted entry of •

outside air if the ventilator is turned off while the furnace air handler continues to operate.

GETTING

STARTED

Balancing Airﬂow

Balancing the airﬂow veriﬁes that the Fresh Air

Ventilation System is delivering the intended airﬂow

and energy performance. Use the Airﬂow Balancing

instructions in the Installation section to check and

balance the airﬂow.

Controls

Remote Override Switch Functions On/Off Control

If continuous ventilation is not required, an on/off

control can be used to activate the ventilator when it is

switched to Standby. Controls that can be used for this

function include dehumidistats, timers, wall switches

and the ventilate function of the VisionPRO IAQ and

TrueIAQ digital controls.

Dehumidistat

If moisture control in bathrooms is a primary function

of the system, a dehumidistat can be used to switch

the ventilator from a Low or Standby setting to the High

setting. Moisture removal throughout the entire home

can only be achieved when the outside air contains

less moisture than the inside air (typically during cold

weather conditions).

An HRV will override a call from the dehumidistat if

the outdoor temperatures exceed 60°F (15.6°C) for

a 24-hour period. The dehumidistat function will be

re-enabled if the unit is unplugged for 3 minutes or if

the outdoor temperature drops below 60°F (15.6°C)

for a 24-hour period. The dehumidistat function is

permanently enabled in ERVs.

IAQ Controls

The VisionPRO IAQ and TrueIAQ controls can

automatically control the ventilator by pressing the

Ventilate button on the control. See the control owner’s

guide for complete instructions.

Digital Fan Timer

The ventilator controls are compatible with the Digital

Fan Timer. If more than one timer is activated, each

runs independently with the ventilator running at high

speed until all timers have timed out. Up to eight timers

can be installed in a system.

Moisture Control

When a building is new, there is excess moisture in

the wood, plaster, cement and other construction

materials. When the new building is occupied, the

activities of the occupants also increase the moisture

level. There can also be high levels of formaldehyde

and other chemicals that were used in the building

materials. Running the ventilation system on high

speed provides optimum indoor air pollutant reduction.

High speed also provides maximum moisture removal

when the outside air contains less moisture than the

inside air. (Typically during cold weather conditions.)

Operating Damper Frost Control

Some models have an electronically-controlled damper

frost control mechanism to prevent frost buildup on the

core. Defrost timing will change based on incoming

outdoor air temperature.

Outdoor Temperauture Defrost Timer*

27 °F (-3 °C) 3 minute defrost/25 minute run

-4 °F (-20 °C) 4.5 minute defrost/17 minute run

-31 °F (-35 °C) 7 minute defrost/15 minute run

* The R2000 jumper on the control board can be

removed to meet R2000 program requirements.

Example:

When the outside temperature drops below 27 °F

(-3 °C), the defrost timer is activated. At the end of the

25 minute run cycle, when the core can experience

some nominal frost buildup, the timer activates a

motor-driven damper door that simultaneously opens

the defrost port and closes off the supply air port.

WIRING

CAUTION: Electrical shock hazard.

Can cause personal injury.

Be sure ventilator is correctly grounded. Conﬁrm polarity of power line switched with safety (disconnect)

switch when cleaning or servicing unit.

IMPORTANT

The hot line (black) is the correct line to switch. See Fig. 19. To conﬁrm correct polarity, use voltmeter or test lamp to

verify there is no power after the switch when the door is open. Check between that point and ground (on cabinet). This

process must be used because occasionally some dwellings are incorrectly wired.

CAUTION: Electrical hazard.

Can cause equipment damage.

Disconnect HRV/ERV from power source before connecting or disconnecting digital fan timer or other

device to HRV/ERV high-speed override terminals.

IMPORTANT

Do not connect external power sources to the highspeed override terminals.

Heat Recovery Ventilator (HRV) and Energy Recovery Ventilator (ERV) Connections

The connector is a three-prong, 120 Vac plug with ground. If further wiring is required, Honeywell recommends

that a licensed electrician make all electrical connections. It is very important that the unit be correctly grounded.

DUCTING

Airﬂow Balancing

Volume-balanced airﬂow in the ventilator is required. Volume of outside air brought in must equal the volume of

air the unit exhausts. If airﬂow is not correctly balanced:

unit does not operate at its maximum efﬁciency.•

negative or positive air pressure can occur in the house.•

unit will not defrost properly.•

warranty can be voided.•

Excessive positive pressure can drive moist indoor air into building external walls where it can condense (in cold

weather) and degrade structural components. Moist indoor air can also cause keyholes to freeze.

Excessive negative pressure can have several undesirable side effects; in some geographic locations, soil

gases such as methane and radon can be drawn into the home through basement/ground contact areas.

Excessive negative pressure can also cause back drafting of vented combustion equipment when adequate

combustion air supply is not provided.

Balancing Procedure

Six-inch (150 mm) diameter ﬂow collars connected to inclined or digital manometer, or magnehelic, with

range of 0 to.25 in. (0 to 62.5 Pa) of water are recommended for accurate airﬂow measurements. To avoid

airﬂow turbulence and incorrect readings, ﬂow stations should be located at a distant point of at least ﬁve duct

diameters; for example, 6 in. (150 mm) duct requires ﬁve diameters x 6 in. (150 mm) = 30 in. (76 cm) from

nearest valve or ﬂow restriction. This requirement applies to both stale air to exchanger duct and fresh air to

house duct.

Before balancing, make sure:

all sealing of the ductwork system is completed.•

all of the ventilator system components are in place and functioning properly.•

balancing dampers are fully open.•

unit is on High speed.•

airﬂows in branch lines to speciﬁc areas of house are adjusted before balancing the unit. (A smoke pencil •

used at the grilles is a good indicator of relative airﬂow for each branch line.)

HVAC fan is on for models ducted into HVAC system.•

Balancing airﬂow.Fig. 20.

After taking readings in stale air and fresh air ducts,

duct with lower cfm (L/s) velocity reading should

remain as is, while duct with higher reading should be

dampered back to match lower reading. See Fig. 20.

Return unit to appropriate fan speed for normal

operation.

APPENDICES

When the ventilator is powered up it will go through a self-test and turn on both fan speeds and check damper

operation.

LED on Terminal Board of Ventilator

The terminal board has an LED that ﬂashes to indicate the current mode of the ventilator.

Ventilator Mode Flashing Sequence Description

Standby, Ventilating,

or Off*

½ sec. on followed by 10 sec. off This is the normal operation of the ventilator.

Self-Test 2-½ sec. on followed by ½ sec. off Self-test will turn on both fan speeds and check damper

operation.

Defrost ½ sec. on followed by ½ sec. off See page 9 for defrost operation

* In Off mode the ventilator will not come on. The ventilator is in Off mode when there is no jumper between

VNT COM and RED. The jumper can be replaced with an ON/OFF light switch to provide an easy positive off

switch.

STARTUP AND CHECKOUT

SERVICE

CAUTION: Electrical shock hazard.

Can cause personal injury or equipment damage.

Disconnect power to unit before starting

maintenance.

For maximum efﬁciency, the Fresh Air Ventilation

System must be maintained on a regular basis.

Honeywell recommends checking and cleaning at

least twice a year, preferably at the beginning of each

heating and cooling season.

Cleaning Filters and Core

Open ventilator door by loosening draw latches on top of 1.

unit and swinging door open. For easier access, remove

door by moving it right to disengage hinges.

Carefully grip ends of core, (be careful not to damage 2.

aluminum ﬁns); then pull evenly outward. Core ﬁts tightly,

but slides out of channels.

Once core is removed, ﬁlters can be removed by 3.

removing clips holding them in place. Note clip

installation for reassembly.

ERV core: Vacuum the ERV core or rinse with cold water. 4a.

Do not use soap, dishwasher, or a pressure washer.

HRV core: Soak and rinse the HRV core in warm soapy 4b.

water. Do not use cleaning solutions, dishwasher or a

pressure washer.

Wash the ﬁlters in warm soapy water.5.

Place the clean ﬁlter (wet or dry) over the core and 6.

secure it in place with the clips.

Reinstall core by sliding it into the four corner channels. 7.

(Water cannot damage gasket and label on core ends,

so it is not necessary to remove them from the core.)

Inspecting Exterior Hoods

Inspect exterior hoods at least monthly. Be sure

exhaust and fresh air supply hoods are not blocked

or restricted by leaves, grass or snow. In winter, be

sure snow does not block hoods and frost does not

accumulate on wire mesh bird screen.

IMPORTANT

Blocked hoods can cause house/building pressure

change that can lead to possible combustion product

spillage from heating appliances.
