BROAN ERVS100S Series Energy Recovery Ventilator Instruction Manual

The Broan ERVS100S is an effective, balanced ventilation solution featuring integrated humidity sensing to limit ventilation during periods of excessive outdoor humidity, thus contributing to a more comfortable indoor environment. This energy recovery ventilator (ERV) provides a supply of fresh, filtered air to the home while exhausting the stale polluted air, thus improving the overall indoor air quality.

  • Compact, low profile platform that can be mounted in a ceiling cavity featuring a pre-painted white access door that can blend into the interior space;
  • Power cord ready design;
  • Integrated humidity sensor limiting the ventilation during periods of excessive outdoor humidity, contributing to a comfortable living indoor environment;
  • Integrates with existing forced-air furnace ducting for easy installation but runs independently to limit energy consumption related to ventilation;
  • Built-in damper on fresh air supply port to prevent outdoor air infiltration when the unit is turned off; · Integrated control to easily set the unit at installation with an optional external wall control to boost the unit to high speed.

Product balancing

The ERVS100S is equipped with 2 high static pressure blowers and is factory balanced. Once installed, the ERVS100S will remain balanced (within a 10% total difference between the exhaust and supply airflows) when the static pressure difference between the exhaust and the supply remains below 0.2 in. w.g. No balancing dampers are required when this condition is met.

Repairs and maintenance

All parts requiring maintenance can be removed in less than 5 minutes allowing easy access for repairs. The PSC motors are permanently lubricated.

Warranty

The BROANTM ERVS100S is protected by a 5-year warranty on parts only. The energy recovery core is covered by a 5-year warranty, with the original proof of purchase.

Safe Installation Zone

This unit is designed for installation where the outdoor temperature is above 14°F throughout the year (zone A on map below). For units installed in zone B, they must be installed in conditioned space or in the ceiling with a surrounding sealed enclosure, see section 3.1.3 of the installation and user guide.

Combining with an AHU

Recommended configurations Option 1 – When the distribution of fresh air from the ERV is connected to the return of an AHU (such as in the image below, on the left), static pressure where the fresh air from the ERV enters the AHU return ducting must be below 0.15 in.w.g. to ensure proper functionning of the built-in fresh air damper. If return duct static pressure exceeds the 0.15 in.w.g. threshold, an indirect connection combined with a supplemental return grille or “T” connection with the conditioned space should be used. See the User and Installer guide for more details.

Relative humidity limit

The ERVS100S monitors the outdoor air conditions (temperature and humidity level) every 10 minutes with a built-in sensor. When
the outdoor conditions are above the set limits, the unit will limit the ventilation to 10 minutes per hour and come back to its previous setting when the conditions get back to the set limit. The accepted RH limit varies in function of the outdoor conditions and can be adjusted to 4 different positions:

BROAN ERVS100S Series Energy Recovery Ventilator Instruction Manual - Relative humidity limit

* The RH limit of distributed air is calculated at 75°F.
** When the outdoor temperature is equal or above 73°F, the maximum relative humidity level accepted is higher considering that the air conditioning will partly dehumidify the incoming fresh air after it is distributed and mixed with the conditioned indoor air.

Optional controls wiring

-Broan VB20W 20-minute push-button control: Activates 105 cfm speed in all ventilation modes (recommended when the unit exhausts from a bathroom).
-Dry contact standby switch: Unit remains powered on, but is put on Standby mode when the switch is turned on.

This connection allows the operation of VB20W push-button controls even if the dry contact standby switch is turned off.
