1.1 DESCRIPTION
SOLID STATE SPEED CONTROLS FOR MOTOR & BLOWER SPEED CONTROL OF
RENEWAIRE EV450 AND HE1X ENERGY RECOVERY VENTILATORS
RenewAire single-phase EV450 and HE1X (non-ECM) indoor and rooftop units can be operated using solid
state speed controls following the procedures below.
Electrical specifications are identified on the unit rating label (located near the electrical box). Locate
the voltage (V) and phase of each motor on the unit rating label. Select the solid state speed control
appropriate for the voltage rating on the label. Solid state speed controls may be used only to control
single-phase EV450 and HE1X indoor and rooftop units.
2.0 INSTALLATION
2.1 PROCEDURES
1. Ensure power is disconnected to the unit prior to opening electrical box. See Warnings on
page 2 of this manual.
2. The electrical box of the unit contains existing wiring harnesses that connect the contactor
to the motor wiring harnesses. For motors which will receive solid state speed controls,
these wiring harnesses will be replaced with a new harness, which is provided.
3. NOTE: Do NOT remove harnesses that directly connect the motor to the electrical box.
4. There are multiple electrical knock-outs located at the base of the unit electrical box to
attach conduit for routing wires for the solid state speed controls. Only remove the number
of knock-outs needed.
5. Remove the existing wiring harness inside the electrical box that connects the unit contactor
with the motor wiring adapter harness. See the chart below to identify the part number of
the existing wiring harness to be replaced.
6. Replace the existing wiring harness with the wiring harness from the kit. This harness is
modified to accept the connection to and from the solid state speed control, which is to be
wired in series with the speed-controlled motor and line voltage. Discard the original wiring
harness which was removed from the unit.
7. Use the two-position wire connectors which are attached to the replacement wiring harness
to connect field-supplied wiring that will run from the unit out to the solid state speed
control.
8. Use the provided wiring ties to secure and tidy replacement wiring harness inside the unit
electrical box.
9. Properly route field-supplied wires from the unit to the location of the solid state speed
controls. Use the loose wire connectors supplied with the kit to connect the solid state
speed controls in series with the unit wiring.
10. Ensure that the solid state speed controls are properly grounded per the speed control
manufacturer instructions. Use the provided wire connector to attach field-supplied ground
wire to the speed control.
11. Ensure that solid state speed controls are properly installed in a standard electrical box and
secured per control manufacturer instructions.
12. Ensure all electrical boxes and unit doors are properly closed.

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. For more information, visit: renewaire.com
