OPERATION
The Push Button Boost Timer (PBT) point-of-use control with indicator light is compatible with RenewAire Energy Recovery Ventilator (ERV) models EV Premium and SL70. The PBT will operate your ERV for either 20, 40, or 60 minutes based upon how many times the logo button has been pushed. The indicator light on the front of the PBT control is on whenever the ERV is operating, unless operating due to an additional control wired directly to your ERV. 20-40-60 MINUTE VENTILATION CONTROL: Press the logo and your ventilator will run for 20 minutes. Press again and the unit will run 40 minutes. A third press provides for 60 minutes of operation. You can cancel a cycle at anytime. Just press the logo for a fourth time. You can start another cycle by pressing the logo.
