Venmar Constructo 1.0 Air Exchange
and Energy Recovery Ventilation Systems

Air Exchanger Systems for Home Ventilation

Diagram Fresh Air In Stale Air Out Venmar Ventilation Constructo Energy Recovery Ventilators are the comfortable home solution for improved indoor air quality. Venmar ERV ventilation systems are a very popular choice and one of the best Energy Recovery air exchangers (ERV) of its category. Constructo air exchangers deliver an exceptional level of indoor air quality and excess humidity control.

Featuring a robust polypropylene core, the Constructo series provides mid-size (refer to local building code) homes with fresh air all year and retains heat in colder climates for improved home comfort. Versatile main and optional wall controls make it easy to manage excess humidity and air flow throughout the home.

Energy Recovery Ventilator (ERV)

The Venmar Constructo 1.0 energy recovery ventilator (ERV) is suitable for all climates including those with hot, humid summers, where homes are air-conditioned and possibly dehumidified during large parts of the year. As the unit recovers the heat in cold season, however, it also recuperates the energy trapped in moisture, which greatly improves the overall recovery efficiency. The ERV process is as follows: In humid climates and air conditioned homes, when it is more humid outside than inside, the ERV limits the amount of moisture coming into your home. In dry climates and humidified homes, when the humidity level is reversed, the ERV limits the amount of moisture expelled from your home.

Constructo 1.0 ERV Energy Recovery Ventilation

The Constructo 1.0 ERV is ingenious air exchange solution thats as versatile as it is compact. Configured with factory built vertical or horizontal ports, the Constructo 1.0 can fit almost anywhere. Tucked in a bulkhead or closet, its the most versatile 100 CFM unit available on the market today. This compact, lightweight, and powerful unit is the ideal choice for small prefab and tract houses and other limited space applications. Whats more, it is the only air exchanger of its size that can be transformed from an Energy Recovery Ventilator (ERV) to an Heat Recovery Ventilator (HRV), simply by changing its core. The Constructo 1.0 ERV is available in horizontal or vertical ports.

Constructo 1.0 ERV Documentation

Tandem Transition Kit

The Tandem Transition Kit ONLY works with Venmar units with 110 cfm or less: HEPA 3100 HRV, HEPA 4100 ERV and Constructo 1.0 (both ERV and HRV). This kit is included in the HEPA installation kit, but it can be ordered separately. This exclusive Venmar fixture makes installing your air exchanger fast and easy and only requires a single hole in your exterior wall. Tandem Transition Technical Sheet

Main Wall Control Options

Constructo Wall Control

The Constructo main wall control can only be used on Constructo models and adjusts the air supply speed using the sliding button:

OFF
MIN (low speed air exchange)
MAX (high speed air exchange).

Also, the maximum indoor humidity level for your house is selected by the knob. Constructo Light Touch Main Wall Control image

Constructo Light-Touch Wall Control

The Constructo Light-Touch main wall control can only be used on Constructo models. The light indicator color of this wall control shows clearly in which operating mode the unit is. This push-button control has three functions:

Intermittent (low speed air exchange during
20 minutes, then stops during 40 minutes)
Min (low speed air exchange)
Max (high speed air exchange)

Constructo Simple Touch Wall Control (Constructo 1.0 Only)

The Constructo Simple-Touch main wall control is exclusively used on the Constructo ERV 1.0 model. The light indicator color of this wall control shows clearly in which operating mode the unit is. This push-button control has three functions:

Recirculation (stops exchanging air with the outside and recirculates inside air at high speed)
Min (low speed air exchange)
Max (high speed air exchange)

Venmar Deco-Touch Main Wall Control

The Deco-Touch main wall control allows the user to choose either the manual modes or the automatic mode (dehumidistat). Operation Features include:

RECIRC MODE - In this mode, the air is recirculated inside the house at high speed.
20 MIN/H MODE - The ventilation unit exchanges air intermittently on a one-hour cycle as follows: OFF for 40 min. (or recirculation on high speed for 40 min.) and then exchanges air during 20 min. on low speed. Repeats cycle after the 20 min. of air exchange.
MIN MODE - Air is exchanged with the outside on low speed.
MAX MODE - Air is exchanged with the outside on high speed.
HYGROMETER - In the operating modes listed above, select a dehumidistat override so that if the relative humidity (RH) in the house exceeds the RH setting previously stored, the ventilation unit will exchange in high speed until the target indoor RH setting is reached.

Altitude Wall Control (Constructo 1.0 Only)

SMART Mode automatically controls ventilation to maximize homeowner comfort, using indoor and outdoor humidity level and temperature to modulate ventilation:

PROGRAMMABLE Mode optimizes and reduces energy usage.
VENTILATION Mode offers 6 convenient settings:
- MIN / MAX
- 40-min/h / 30-min/h / 20-min/h
- OFF
- RECIRCULATION Mode Offers 3 convenient settings: MIN / MAX / OFF.

Optional Wall Controls

20-Minute Lighted Push-Button

This timer allows the unit to provide 20 minutes of high speed ventilation at the push of a button, to expel rapidly indoor stale air. Lighted when activated, up to five of them can be installed (e.g.: in bathroom, kitchen, laundry room, etc.)

60-Minute Mechanical Timer

This timer allows up to 60 minutes of high speed operation.

Maintenance

Regular maintenance should be performed every 3 months. Annual maintenance should also take place every fall season. Remove filters.

Vacuum to remove most of the dust.
Wash with a mixture of warm water and mild soap. Rinse thoroughly. Shake filters to remove excess water and let dry. NOTE: Washing the filters in the top tray of the dishwasher is possible, but the aluminum frame might tarnish.
Replace the optional filters (electronic, pleated or charcoal) if applicable. Do not wash in water.
Check the exterior air intake hood. Make sure no leaves, twigs, ice or snow have been drawn into the vent. Clean if necessary.

Get the Ultimate in Clean Air for Your Home

Combine an Air Oasis Induct Air Purifier with a Venmar Ventilation System (or any HVAC system) and get the ultimate in pure air in your home.

The Venmar Air Exchange System is fabulous for recovering heat or energy, providing fresh air, controlling humidity and removing particulate (dust, pollen, dander, etc.), but by adding the powerful broad-spectrum pollution purification abilities of an Air Oasis HVAC Induct Air Purifier, you get the ultimate in whole-house clean air. Air Oasis air purifiers destroy bacteria, viruses, pesticides, herbicides, mold spores, chemical fumes and gases, VOCs, odors and more from your ductwork and every room served by a vent.

The ONLY Induct Air Purifier with Rotational UV Shield Technology

Since UV lamps were first used in HVAC systems there has been one constant complaint from HVAC engineers and contractors. UV light can degrade many of the rubbers and plastics used within an HVAC system causing premature system failure. Air Oasis has created the perfect solution. With the development of their proprietary Rotational UV Shield you can control how little or how much UV light is emitted from the unit, while allowing for a constant stream of air to pass through the AHPCO Cell for treatment. The Rotational UV Shield can be rotated 360 degrees exposing more or less of the UVC lamp. (Click here to read why most induct UV lamps are not as effective as claimed).

The residential and business HVAC (heating, ventilation and air conditioning) induct models are designed for use with forced-air heating and central air conditioning systems (HVAC) to purify the air in all rooms served by ductwork in small to large single-family homes and office buildings. Turn your central heating and cooling system into an air-cleaning machine to significantly reduce pollutants and contaminants in your entire home or business.
