TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 2 of 34 General Product Description 1.1. Product Overview & Description • Indoor air in homes often contains significantly more unhealthy pollutants than outdoor air, making it a significant contributor to poor indoor air quality. Air ventilation can be used to improve indoor air quality by exchanging stale indoor air with fresh outside air.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 3 of 34 1.2. Market Objectives HRV and ERV solutions are installed as an energy efficient way of bringing fresh air into the home and exhausting stale air from the home. Many contractors install ventilators today to either satisfy building codes or to help protect the home and its residents from poor indoor air quality. Installing ventilation products today can be expensive, tedious and time consuming.

TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 5 of 34 2. General Product Specification 2.1. Theory of Operation Cross-flow Core VNT5070 Series An HRV transfers only sensible heat while an ERV transfers both sensible heat and latent heat (moisture exchange) between air streams. In cold climates, both HRVs and ERVs can be effective at removing moisture from the indoor space by exhausting moisture laden air and replacing it with dry air from outdoors.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 6 of 34 2.2. Product Construction & Accessories The Honeywell compact ventilator is comprised of the following components (also see exploded view in section 1.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 7 of 34 2.2.4. Defrost Cycle The ventilators are equipped with an automatic “supply fan shut down” defrost feature to eliminate any ice build up on the heat recovery core or energy recovery core. The automatic defrost cycle is initiated by a temperature sensor located in the fresh air intake.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 8 of 34 Ventilation mode: OFF, CONT or INTER. Off mode: The ventilator will remain off and will not respond to any ventilation request. Continuous mode: The ventilator is powered and is continuously exchanging stale indoor air with fresh outdoor air on low speed ventilation, except when there is a request for high speed ventilation from a remote control.

TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 14 of 34 3. Product Requirements 3.1. Product Wiring & Control Ventilator Power Honeywell ventilators are rated at 120VAC, 60Hz, 0.85 Amps (maximum) power requirements. The ventilator is powered by a 5-foot (nominal) power cord, 18AWG wire with NEMA 15-5 receptacle plug. A dedicated 120 VAC receptacle near the ventilator is recommended; use of extensions cords is not recommended.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 15 of 34 VNT5070 series Blower Motor Wiring Diagram Remote Control - Low Voltage Wiring The ventilator can be wired externally to low-voltage devices such as thermostats, controllers, dehumidistats, boost controls, etc. allowing for remote control of the ventilator.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 16 of 34 CONT mode - a ventilation call from a wall control boosts the ventilator from low speed to high speed. • Interlock panel NO-COM relay contacts are always closed, i.e. continuously calling forced air furnace blower. INT mode - a ventilation call from a wall control turns the ventilator ON to HI-speed. • Interlock panel NC-COM relay contacts are closed in OFF position.
TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 17 of 34 2) Wiring Diagram – HVAC Interlocked: The ventilator IS interlocked with the forced air system and is used in conjunction with a conventional HEAT/COOL thermostat (or other wall control) with ventilation contacts. Ventilator mode: INT. In normal operation, a fan demand from the wall control (thermostat) will pass through the ventilator NC terminal and continue to the HVAC G terminal, thereby turning on the HVAC fan.

TrueFRESH Compact Ventilation System Honeywell VNT5070 Ventilator Page 19 of 34 3.2. Airflow Balancing The VNT5070 ventilators are provided with pressure ports located on the duct collars and are used to balance the ventilator during installation. Pressure measurements are made across the high and low ports of each airstream (Fresh & Exhaust) and then compared to an airflow correlation table (decal on the unit) to find the corresponding air flow rates.
