SPTL S&P percentage timer controller for TR Series ERV

Percent Timer Control-Lighted For use with TR70/TR130/TR200/TR300

Operation

The Percent Timer Control-Lighted (SPTL) automatically turns on your TR70, TR130, TR200 or TR300 Total Recovery for All Climates unit every hour, ensuring proper ventilation for your home around-the-clock. When the “Runtime %” light is on, the control is telling your Total Recovery for All Climates unit to operate. Set the control and your ventilator will run once every hour. How long it runs depends on the runtime percentage setting.

FOR CONSTANT OPERATION: Press the logo until the 100% light is on. The “Runtime %” light turns on. The TR unit will run continuously.

FOR REGULAR OPERATION: Set the control at the percentage that is right for your home. Press the logo until the light for the percent desired is on. See the "Percent Run Time Table" for guidance. You may wish to adjust this percentage to your specific needs. For example, if you have excess humidity in the winter, increase the ventilation percentage. You may also want to decrease the ventilation percentage when the home will be unoccupied for many days, or increase the ventilation percentage during a party.

FOR NO REGULAR OPERATION: Press the logo until all lights are off. The control is off.

NOTE for TR systems with more than one control: Another control may be causing your ventilator to run. If you wish to keep your ventilator from running, check that none of your controls are calling for unit operation.
