OVERVIEW

DESCRIPTION

RenewAire’s light commercial units are offered with optional electronically commutated motors (ECM). EC motors have higher efficiencies with considerable energy savings over a standard permanent split capacitor motor. The ECM offered in RenewAire energy recovery ventilators (ERVs) are constant torque with a variety of speed control options. The motors operate at fixed speed or variable speed with speed inputs from circuit board-mounted trimming potentiome- ter(s), panel-mounted potentiometer(s), or 0–10 Vdc analog signal.

OPERATING CONTROLS

A wide variety of low voltage (24 VAC) control schemes may be selected to meet the ventilation needs of the facility. These include time clock, occupancy sensor, carbon dioxide sensor, and others. Building Management Systems (BMS) may also control the unit with external control by others.

INSTALLATION

PRINCIPLES OF EXTERNAL CONTROL

The light commercial units with EC motors are designed for control by a wide variety of low voltage (24 VAC) controls to meet the ventilation needs of the facility. These include time clock, occupancy sensor, carbon dioxide sensor, BMS, and others. These devices are commonly known as 2-wire, 3-wire, and 4-wire devices. RenewAire offers separately the following for standalone control of the ERV:

Digital Time Clocks TC7D-W and TC7D-E
Occupancy Sensors MC-C and MC-W
Carbon Dioxide Sensor/Controllers CO2-W and CO2-D
Indoor Air Quality Sensor/Controllers IAQ-W and IAQ-D

OPERATION

AIRFLOW PERFORMANCE

The ERV is factory wired to operate at low adjustable SPEED 1 and variable SPEED 2.
Airflows must be measured and the unit’s potentiometers adjusted so that it operates at the airflow volumes specified for the installation.
Use the pressure taps in the core and filter doors to determine the airflow. Section 4.3 translates the pressure drop across the energy recovery core to the actual airflow volume.

MEASURING AIRFLOW

Equipment Required
Magnehelic gauge or other device capable of measuring 0–1.5 water of differential pressure.
2 pieces of flexible tubing, 1/8″ ID, 1/16″ wall works
Cross Core Static Pressure Measurement Instructions
The individual differential pressures (DP) are measured using the installed pressure ports located in the front of the units core access
To read SCFM of Fresh Air (FA) install the “high” pressure side (+) of your measuring device to the Outside Air (OA) port and the “low” pressure side (-) to the Fresh Air (FA)
To read SCFM of Room Air (RA) install the “high” pressure side (+) of your measuring device to the Room Air (RA) port and the “low” pressure side (-) to the Exhaust Air (EA)
Use the reading displayed on your measurement device to cross reference the CFM output
Adjust airflow by changing the potentiometer setting for the measured

FACTORY ASSISTANCE

In the unlikely event that you need assistance from the factory for a specific issue with the ERV or its ECM Option, make sure that you have the information called for in the Unit Records pages at the front of the ERV manual. The person you speak with at the factory will need that information to properly identify the unit and the installed options.
To contact RenewAire Customer Service:
Call800-627-4499

Remember that RenewAire Customer Service can only assist with the ERV and its options, it cannot resolve engineering issues that result from air handling system design by others.

About RenewAire

For over 30 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ) in commercial and residential buildings of every size. This is achieved while maximizing sustainability through our fifth-generation, static- plate, enthalpic-core

Energy Recovery

Ventilators (ERVs) that optimize energy efficiency , lower capital costs via load reduction and decrease operational expenses by minimizing equipment needs, resulting in significant energy savings. Our ERVs are competitively priced, simple to install, easy to use and maintain and have a quick payback. They also enjoy the industry’s best warranty with the lowest claims due to long-term reliability derived from innovative design practices, expert workmanship and

Quick Response Manufacturing (QRM).

As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV producer in the USA. We’re

committed to sustainable manufacturing

and lessening our environmental footprint, and to that end our Waunakee, WI plant is 100% powered by wind turbines. The facility is also one of the few buildings worldwide to be LEED and Green Globes certified, as well as having achieved ENERGY STAR Building status. In 2010, RenewAire joined the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the latest in energy- efficient air-moving technologies.
