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 off 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 off. The control is off. When set to off,
your furnace/air-conditioning blower will run based upon your thermostat or other controls.
