RenewAire FM Percentage Timer Control with Furnace Interlock

Installation Manual

Operation:
The Percentage Timer Control with indicator lights and furnace interlock (FM) is the primary control for RenewAire Energy Recovery Ventilator (ERV) models EV90, EV90P, EV130, EV200, EV240 and EV300 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 airconditioner 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. 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 and furnace/air-conditioning blower 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. No Operation Press the logo until all lights are off. The control is off. When set to off, your furnace / air-conditioning blower will run based upon your thermostat or other controls.
