OPERATION
The Percentage Timer Control with indicator lights and furnace interlock (SFM) is the
primary control for S&P USA Energy Recovery Ventilator (ERV) models TR90, TR130,
TR200, TR300, TRe200, TRe300, and TRLPe100/TRLPe100c when Furnace Interlock is
needed and no Push Button Lighted (SPBL) controls are used. This proportional runtime
control will operate your ERV an adjustable amount of time each hour as well as tell your
furnace or air-conditioner to circulate air throughout your home at the same time, if not
already doing so. When the “Runtime %” light is on, the SFM control is telling your ERV
and furnace/air-conditioning blower to operate. Additionally, the SFM can be set to turn
your ERV o󰀨 or to operate constantly. ERV operation time will vary from application to
application as well as time of year, lifestyle, indoor air quality concerns, and other factors.
Discuss any questions with your HVAC professional or contact S&P USA directly.
FOR CONSTANT OPERATION: Press the S&P logo until the light next to “100” is lit.
OPERATION EACH HOUR: Run time of your ERV and furnace/air-conditioning blower
can be adjusted from 10%, or 6 minutes each hour, up to 100% operation in 10%
increments. Simply press the S&P logo until the light next to the desired percentage
amount is lit. You can increase or decrease the run time based upon daily, weekly, or
monthly variations in occupancy levels, indoor odors, cold weather winter humidity, or other
indoor air quality concerns as needed.
NO OPERATION: Press the logo until all lights are o󰀨. The control is o󰀨. When set to o󰀨,
your furnace/air-conditioning blower will run based upon your thermostat or other controls.
INSTALLATION
1. Install control in a standard 2" x 4" electrical box, with a minimum depth of 1.5", with
the two screws provided.
2. Wire Size: 18–22 gauge, no more than 500 feet. Wiring is non-polar.
3. See the wiring schematics for your specic installation.
4. Use Lutron Decora™ cover plate to complete installation (single cover plate included).

WIRING OPTIONS 3 AND 4: The SFM requires 24 VAC power to operate. This is usually provided by the furnace
control. If there is no Furnace connection, it is possible to power the SFM with an external transformer; in this
case, make no connections to any appliance other than the TR90, TR130, TR200, TR300. Use Option 3 or 4 when
connecting a larger commercial Energy Recovery Ventilator unit.
WIRING OPTIONS 1 AND 2: In most Furnace/Thermostat systems, if a circuit is made between R and G on the
furnace, in an attempt to make the furnace blower operate, the Y contacts are also energized, because the thermostat
has an internal connection between its G and Y terminals. This will cause the air conditioning unit to operate as well.
The Furnace Interlock in the SFM takes the thermostat’s G terminal out of the circuit whenever there is a call for the
Energy Recovery Ventilator to operate.
