ERVS&P TReNHVI 2005459
S&P TReN200
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.

HVI certified
HVI 2005459
The Home Ventilating Institute tested its airflow and heat recovery. The certified numbers on this page come from its directory. Find HVI 2005459 in HVI’s directory
ENERGY STAR (Canada)
Not on the list
Not on Natural Resources Canada’s ENERGY STAR list when we checked. ENERGY STAR certifies HRVs and ERVs only in Canada, so a unit sold in the U.S. may never have been submitted; that isn’t a sign it’s less efficient. Its HVI numbers show its heat recovery and fan power. NRCan’s ENERGY STAR list (checked October 19, 2026)

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.

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) | 51 cfm | 81% SRE | 19 W | 2.6 |
| 32°F (0°C) | 102 cfm | 73% SRE | 40 W | 2.5 |
| 32°F (0°C) | 150 cfm | 68% SRE | 81 W | 1.8 |
| 32°F (0°C) | 203 cfm | 62% SRE | 177 W | 1.1 |
| 95°F (35°C), cooling | 51 cfm | 77% TRE | 20 W | – |
- Plain fact: Keeps 62–81% of the heat at 32°FAcross the airflows HVI tested.
- Not stated by the maker: No very-cold (−13°F) test in the HVI directory
- Plain fact: Total recovery in summer: 77% 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 S&P CO2 control listed for this modelS&P lists its SCO2-W (600 to 2,000 ppm) for its TRC and TRPLe units. Ask S&P about this one.
What S&P (Soler & Palau) documents
- Plain fact: S&P’s SCO2-W CO2 control: 600 to 2,000 ppmS&P lists it for its TRC and TRPLe units, not the TRe.
- Not stated by the maker: The TRe’s boost terminals aren’t statedIt lists a boost (high speed) mode and a low-voltage control circuit.
Four ways to make it turn up by itself
A night scheduleAsk your installer
Ask what its controls can schedule.
Its maker’s CO2 controlAsk your maker first
The SCO2-W is listed for TRC and TRPLe; ask S&P about your model.
A CO2 control on its high-speed inputAsk your maker first
Its boost input isn’t documented; ask S&P.
Your monitor and a smart-home relayAsk your maker first
Not documented by S&P.

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.
Thinking about a system?
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.
