INSTALLING CONTROLS
Optional controls:
RenewAire offers a variety of controls specifically designed to work with the EV130/200/300 products. These
include: PTL (a two wire percentage timer), FM (a six wire percentage timer that will interconnect with
the furnace blower), and PBL (point of use push button control). Other controls that throw an unpowered
switch may also be used.
Typical control schematic:
Various wiring designs can be used to properly control the unit and meet safety and code concerns. Consult
your electrician for an electrical design to meet your needs.
The schematic below (F7) shows a typical control system: a PTL percentage timer plus two PBL
push-button controls.

STARTING UP THE UNIT
• Inspect your installation to be sure all duct work
is correctly installed and sealed, that filters are
in place, and controls (if any) are connected.
• Shut and latch the door to the unit.
• Plug unit into 115 VAC outlet. It may start
immediately.
• Use control to turn on the unit. Check operation
of the control(s).
• Check that the unit’s safety interlock switch
turns off the unit when the door is opened.
See installation manuals for the control(s) you select for wiring diagrams and specific instructions.
If NOT connecting controls to the ERV:
Make a jumper out of a short piece of wire. ERV will run full-time once its power cord is plugged in.
