Panasonic Intelli-Balance 200 (FV-20VEC1)
Energy recovery ventilator (ERV). Moves heat and some moisture between the outgoing and incoming air, so dry winter air keeps more of the home’s humidity and humid summer air brings in less.

The collars can turn to point sideways; they’re drawn pointing up. The numbers are ours, the same on every unit.

At a glance
- In its favour: HVI-certified (HVI 2004772)Its airflow and efficiency were tested to the Home Ventilating Institute’s standard.
- Plain fact: 201 cfm at 0.4 in., 182 cfm at 0.5 in. of duct pressureCertified fresh air delivered, at HVI’s headline rating point and at the higher pressure many real ducts run at.
- Not stated by the maker: No Panasonic CO2 controlIts wall control’s boost button runs 10 to 60 minutes; its guide mentions no input for an outside control. Ask your installer.
- Plain fact: How it handles frost in very cold weatherBuilt-in frost prevention mode. The defrost cycle starts when the outdoor temperature drops to 14°F (-10°C), using built-in dampers on the outdoor-exhaust and supply ducts. The documents opened don't say how it defrosts or for how long. Panasonic calls it suitable for any North American climate zone.

Certified airflow
How much fresh air it delivers as the ducts push back. More duct pressure, less air: that’s why the installer’s duct design matters as much as the unit.

Heat and moisture recovery
Sensible recovery (SRE) is the share of heat kept in winter, after the fan’s own heat is taken out; total recovery (TRE) counts moisture too, in summer.
| Outdoors | Airflow | Recovery | Fan power | cfm per watt |
|---|---|---|---|---|
| 32°F (0°C) | 68 cfm | 83% SRE | 22 W | – |
| 32°F (0°C) | 125 cfm | 77% SRE | 46 W | – |
| 32°F (0°C) | 170 cfm | 73% SRE | 92 W | – |
| -13°F (-25°C) | 66 cfm | 67% SRE | 46 W | – |
| -13°F (-25°C) | 106 cfm | 61% SRE | 104 W | – |
| 95°F (35°C), cooling | 72 cfm | 70% TRE | 25 W | – |
| 95°F (35°C), cooling | 136 cfm | 61% TRE | 56 W | – |
- Plain fact: Keeps 73–83% of the heat at 32°FAcross the airflows HVI tested.
- In its favour: Tested at −13°F too: 61–67% SREHVI’s very-cold test point, useful in cold climates.
- Plain fact: Total recovery in summer: 61–70% at 95°FThe share of heat and moisture kept out on a hot, humid day.
Turning up on CO2
A CO2 control can switch it to a higher speed when the bedroom needs air, then back. HouseExhale’s setting: up at 750 ppm, back at 650, never above 800.
- Not stated by the maker: No Panasonic CO2 controlIts wall control’s boost button runs 10 to 60 minutes; its guide mentions no input for an outside control. Ask your installer.
What Panasonic documents
- Not stated by the maker: No Panasonic CO2 controlIts Swidget smart controls can boost on their own sensors’ readings, but those list VOCs and air quality, not true CO2.
- In its favour: Intelli-Balance Elite and BalancedHome: a dry-contact boost inputTerminals BST and GND; up to two boost switches. The manual doesn’t say if boost holds while closed.
- Worth knowing: Intelli-Balance 100 (FV-10VEC2): its boost switch is 120 VA low-voltage CO2 relay isn’t made for that. Ask an electrician.
- Plain fact: The Swidget Wi-Fi module can schedule boostFor the Elite and BalancedHome models.

Elite and BalancedHome take a dry contact on BST. The Intelli-Balance 100’s boost is 120 V: an electrician’s job.

Installing it
The maker’s facts an installer plans around. Your installer confirms them for your home.
- Power
- 120 V, 60 Hz. Uses up to 129 W at 200 CFM and 0.4 in. w.g. Panasonic calls it the corded model; amps and plug type are not stated.
- Duct connections
- Four built-in, adjustable 6 in round duct adapters; the supply and return adapters turn from vertical to horizontal. Insulated 6 in duct is recommended, and static-pressure test ports are included for balancing. Built-in dampers sit on the outdoor-exhaust and supply ducts.Scope: adapter turning from the architectural specification; dampers from spec sheet IAQ21056ST
- Size
- Not stated in the sources we found
- Weight
- 117 lb, as listed by SupplyHouse ('may require a lift gate'). SupplyHouse doesn't say whether this is the unit or the shipping weight; Studio41 lists a shipping weight of 116.8 (no units). No Panasonic document opened states the weight.
- Mounting
- Ceiling, floor or wall. Chain mount and brackets are included: adjustable brackets fix it to a joist at four corners, and a cleat hanger bar gives several wall positions. The bracket fits 16, 19 or 24 in stud bays.Scope: stud-bay spacing from spec sheet IAQ21056ST
- Drain line
- No drain line: Panasonic says no condensate line is needed.
- Cold weather
- Built-in frost prevention mode. The defrost cycle starts when the outdoor temperature drops to 14°F (-10°C), using built-in dampers on the outdoor-exhaust and supply ducts. The documents opened don't say how it defrosts or for how long. Panasonic calls it suitable for any North American climate zone.
- Balancing the airflow
- SmartFlow static-pressure compensation; independent 60-200 CFM supply/exhaust presets
- Ducts
- Ceiling/floor/wall; standalone or central-HVAC; no condensate line
- In the box
- A MERV 13 filter, chain mount and brackets, and a cleat hanger bar for wall mounting.
Controls
- Comes with: Not clear. Panasonic's page marks the Intelli-Balance 200 LCD wall control (nine buttons; shows live airflow and temperature) as 'Required'. SupplyHouse sells the FV-SW20VEC1 wall control separately under 'You May Also Need'.
- Wall controls sold: FV-SW20VEC1 Intelli-Balance 200 LCD wall control. The FV-SCVE2 wall control and WP100PBA Wi-Fi module pages do not list FV-20VEC1.
- Boost: Boost from the wall control: supply and exhaust run at a constant 200 CFM on a timer you can set from 10 to 60 minutes. The CO2 research found the wall control's default is 20 minutes.
- App or smart home: None found. The installation manual's contents list a 'COSMOS communication module', but its pages weren't readable.
- High-speed input: No external boost input is described in the sources opened. Forum posts (secondary) say boost uses a switched 120 V signal.

Certified airflow and efficiency from the HVI directory (exported September 23, 2026), joined to this exact model by its HVI number. The maker’s facts from our review of August 31, 2026 and our research of October 17, 2026. This is product information, not a design: your installer confirms the ducts, room-by-room airflow and controls, then measures the airflow after install.

Measure your bedrooms first. When installers quote, the app checks the exact unit they propose, this one or any HVI-certified unit, against what your bedrooms need.
