Fantech HERO 200H

At a glance

• In its favour
• Plain fact
• Worth knowing
• Not stated by the maker

• In its favour: HVI-certified (HVI 2505147)Its airflow and efficiency were tested to the Home Ventilating Institute’s standard.
• Plain fact: 203 cfm at 0.4 in., 195 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: Fantech lists its CO2RT-R as an accessory for the HERO 200H, with no wiring shownIts set-point range isn’t published, so we can’t confirm it reaches 750, and Fantech’s manuals don’t show it wired to a HERO. The D+ and D− input holds maximum speed while closed. Ask Fantech for a wiring diagram first.
• In its favour: Humidity control documented
• Plain fact: How it handles frost in very cold weatherInternal recirculation defrost ('WinterGuard'). It starts when the outdoor temperature falls below 23 °F (−5 °C) and does not depressurize the home.

Certifications

• HVI certified

  HVI 2505147

  The Home Ventilating Institute tested its airflow and heat recovery. The certified numbers on this page come from its directory. Find HVI 2505147 in HVI’s directory

• ENERGY STAR (Canada)

  Listed as HERO 200H

  On Natural Resources Canada’s ENERGY STAR list for HRVs and ERVs, which sets minimums for heat recovery in cold weather and for fan power. ENERGY STAR certifies HRVs and ERVs only in Canada. NRCan’s ENERGY STAR list (search the model number) (checked October 19, 2026)

Would it cover your home?

Tell it who sleeps in each bedroom. It’s checked against the 800 ppm goal the same way the app checks a unit an installer quotes.

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.

Lowest steady airflow (maker)

60 cfm

Highest airflow (maker)

203 cfm

Heat recovery

Sensible recovery (SRE) is the share of heat kept in winter, after the fan’s own heat is taken out. Higher is warmer incoming air for the same airflow.

• Plain fact: Keeps 74–80% of the heat at 32°FAcross the airflows HVI tested.
• In its favour: Tested at −13°F too: 67% SREHVI’s very-cold test point, useful in cold climates.

HRV or ERV: which fits your home?

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: Fantech lists its CO2RT-R as an accessory for the HERO 200H, with no wiring shownIts set-point range isn’t published, so we can’t confirm it reaches 750, and Fantech’s manuals don’t show it wired to a HERO. The D+ and D− input holds maximum speed while closed. Ask Fantech for a wiring diagram first.

Documented control setups for this unit

• Fantech CO2RT-R · 99315Installer confirmation needed

  Switches to high speed. The sensor can close its relay above an adjustable CO₂ setpoint, but the exact response and terminals for the current HERO 200H were not verified in the reviewed model sheet.

  Set it to 750 ppm, if it can be set that low: its maker doesn’t publish its range.

  About the Fantech CO2RT-R

What Fantech documents

• Not stated by the maker: No CO₂ control documented for its home unitsIts CO2RT-R (99315) is sold with its commercial units, and its switch-point range isn’t published.
• In its favour: HERO: a dry-contact input holds maximum speed while closedTerminals D+ and D− (meant for a dehumidistat). A CO₂ relay there should work electrically; Fantech doesn’t document it, and defrost comes first.
• Worth knowing: Never connect 120 V to its control terminalsFantech’s manual says so; a CO₂ relay needs its own 24-volt supply.
• Plain fact: Flex: its boost timers run 20 to 60 minutesA timer input runs its time and stops, rather than staying high.

Four ways to make it turn up by itself

• A CO₂ control on its high-speed inputAsk your installer

  HERO’s D+/D− input holds maximum speed while closed. Undocumented for CO₂: your installer confirms.

• A night scheduleAsk your installer

  A timer on its timer or D+/D− input, or its wall control’s settings.

• Its maker’s CO₂ controlAsk your maker first

  Fantech’s CO2RT-R exists, but Fantech doesn’t show it wired to a HERO or Flex. Ask Fantech first.

• Your monitor and a smart-home relayAsk your maker first

  A dry-contact relay on D+/D−. Not documented by Fantech.

Installing it

The maker’s facts an installer plans around. Your installer confirms them for your home.

Power

120 V, 60 Hz, single phase, 2.0 A, 210 W. A 3-foot plug-in power cord with a 3-prong plug.Scope: 2.0 A max also on Fantech's HERO page, the 2025 brochure and SupplyHouse

Duct connections

6 in (152 mm) round metal duct collars with rubber seals, all on top. The collars have plastic shrouds with built-in backdraft dampers.Scope: 6 in round collars also on the 2023 spec sheet; 'top-mounted' also at SupplyHouse

Size

Height 24 7/8 in (626 mm) × width 27 7/8 in (707 mm) × depth 15 3/8 in (391 mm). The spec sheet adds 23 in as an unlabeled fourth size.

Weight

59 lb (26.55 kg), including the coreScope: the June 2025 brochure also says 59 lb (26 kg); the 2022 product card says 58.5 lb

Mounting

On a wall with the included speed bracket, installed upright; or hung from the ceiling joists with chains, hook screws and springs, kept level. For the 200H the IOM says to move the vibration isolators to the holes shown.Scope: bracket included per the 2023 spec sheet; wall bracket kit 428546 and chain kit 404261 per the 2020 HERO manual parts list

Drain line

Yes: as an HRV it needs a drain line for condensation. The IOM's drain step is 'only necessary for HRV products', and a drain tube comes in the box for HRVs.Scope: family IOM (p. 14); the 200H is the HRV per its spec sheet

Cold weather

Internal recirculation defrost ('WinterGuard'). It starts when the outdoor temperature falls below 23 °F (−5 °C) and does not depressurize the home.

Balancing the airflow

Manual balancing using integrated pressure taps

Ducts

Dedicated or simplified central-HVAC integrations per manual

In the box

Casing, collars, terminals, power cord, long wall bracket, washers, wood screws, chains (4), springs (4), hook screws (4), chain screws, sheet-metal screws, drain tube (HRV) and a balancing chart. No wall control. SupplyHouse also lists the external electrical box with easy-connect ports and collar shrouds with backdraft dampers.Scope: HERO family box list
