FM - PERCENTAGE TIMER FURNACE INTERLOCK - SL, EV, EV PREMIUM AND AERI MT

140470 - FM - PERCENTAGE TIMER WITH FURNACE INTERLOCK - SL, EV, EV PREMIUM AND AERI MT

The Percentage Timer Control with indicator lights and furnace interlock (FM) is the primary control for RenewAire Energy Recovery Ventilator (ERV) models Aeri™, EV, EV PREMIUM, SL, and HE series when Furnace Interlock is needed and no Push Button Lighted (PBL) 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 FM control is telling your ERV and furnace/air-conditioning blower to operate. Additionally, the FM can be set to turn your ERV off or to operate constantly.   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.
