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:

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.

.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

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.

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.

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.

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.

STARTED

GETTING

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.
