Page 11: Overview
Each ERV has two electric blowers, one for each airstream. Fan speeds can be either single speed, or they can be variable speed, controlled by VFDs, a RenewAire Commercial Controller or by a BMS. There are a number of different control devices available to control the operation or speed of the unit fans. -
Page 12: Airflow
OVERVIEW HE-Series Outdoor 1.2 AIRFLOW There are four different airflow options for the HE1.5XRT. They are: HE1.5XRTV HE1.5XRTR HE1.5XRTF HE1.5XRTH HERT except 6x 8x, LERT HERT except 6x 8x, LERT All four configurations include attached hoods for the OA and EA airstreams. The airflow configuration is indicated by digit 9 of the Configuration Code. -

Page 16: Unit Placement
The HE1.5XRT is designed for installation outdoors, typically on a roof top. The preferred mounting method is to place the ERV on an optional manufactured curb, designed for the specific unit. RenewAire recommends the use of optional curb clips to provide substantial resistance to wind damage. -
Page 17: Sound Attenuation
UNIT PLACEMENT HE-Series Outdoor 4.3 SOUND ATTENUATION Take these simple steps to attenuate noise from the unit. 4.3.1 Outside the Building The exhaust hood is the primary source of noise outside the building. When practical, orient the exhaust air hood to point away from houses or public areas. 4.3.2 At the Curb Cut the holes in the roof deck to fit closely around the duct(s) passing through the roof deck. -

(provided) on all bearing surfaces on the curb. Optional installation of owner-provided rails (HE1.5XRTH only): RenewAire recommends that all HE1.5XRT units be installed on a RenewAire-supplied curb that is manufactured to match individual units. The only unit that may be installed on owner-supplied mountings rails is the HE1.5XRTH. -

INSTALLATION HE-Series Outdoor 5.5.4 Control System Sending two 24 VAC “On” Signals (from an external power source) Use Figure 5.5.3 only if the ERV has Independent Blower Control: Make sure the jumper is NOT installed between Terminals 2 and 3. Now you safely can apply one of the 24 VAC signals to Terminals 3 and 4 to operate the ERV’s isolation relay for the Fresh Air Blower. -
Page 25: Control System Operating Isolation Dampers With End Switches
INSTALLATION HE-Series Outdoor 5.5.8 Control System Operating Isolation Dampers with End Switches Use Isolation Dampers with electrically separate end switches. The end switches are used to separately control the ERV unit’s Isolation Relays. Also, specify the ERV with Independent Blower Control. This ensures that each damper is open before the respective blower starts up. Because the ERV’s Motor Starters will only be operating once the Dampers are open, the power draw of the Damper Actuators is allowed to be as much as 35 VA while opening (including power draw of the external control system, if any). -

Page 27: Operation
OPERATION HE-Series Outdoor 6.0 OPERATION 6.1 PRINCIPLE OF OPERATION The HE1.5XRT has one basic purpose: to exhaust air from a structure and bring in fresh air from outside, while transferring heating or cooling energy from the exhaust air to the fresh air. The HE1.5XRT is a very simple device, and will accomplish this purpose as long as the blower is able to move air through the enthalpic core. -
Page 28: Balancing Airflow
OPERATION HE-Series Outdoor 6.3 UNIT START-UP 6.3.1 Fixed-Speed Units Most fixed-speed units do not have any external controlling signals and only require turning on the disconnect switch, located on the E-Box. When the disconnect switch is turned ON, any dampers will first move into their correct operating positions and then power is suppled to the motor contactors, causing the fans to run. -

Page 30: Normal Operation
7.0 MAINTENANCE RenewAire ERVs are built to operate with minimal maintenance. After unit commissioning, the primary areas of attention are the air filters and annual vacuuming of the enthalpic cores. -
Page 31: Filters
MAINTENANCE HE-Series Outdoor 7.4 FILTERS Inspection and replacement of air filters is the most frequent maintenance issue. For units that do not have filter air pressure differential sensors, filters must be visually inspected monthly, as a minimum. If a filter looks discolored or dirty, REPLACE IT! When installing new filters, DO NOT USE filter sprays. -
