RenewAire PTL Percentage Timer Control

Installation Manual

Operation

The Percentage Timer Control with indicator lights (PTL) is the primary control for RenewAire Energy Recovery Ventilator (ERV) models EV90/P, EV130, EV200, EV240 and EV300. This proportional runtime control will operate your ERV an adjustable amount of time each hour. When the “Runtime %” light is on, the PTL control is telling your ERV to operate. Additionally, the PTL 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 RenewAire directly. CONSTANT OPERATION: Press the RenewAire logo until the light next to “100” is lit. OPERATION EACH HOUR: Run time of your ERV can be adjusted from 10%, or 6 minutes each hour, up to 100% operation in 10% increments. Simply press the RenewAire 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. FOR NO REGULAR OPERATION: Press the logo until all lights are off. The control is off. NOTE for ERV 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.
