Description

The S&P SPTL Percentage Timer Controller is the primary controller for the S&P TR series Energy Recovery Ventilators. It features 10 indicator lights that display the percentage of runtime a connected ERV will operate each hour. 

The run time can be increased or decreased based upon daily, weekly or monthly variations in occupancy levels, indoor odors, cold weather winter humidity, or other indoor air quality concerns as needed. Additionally, the controller can set the ERV for continuous operation or to shut it off completely.

Install this controller in a standard 2 x 4-inch control box and connect it to the ERV’s terminal block 18-22 gauge wire.
