During the winter months the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During summer months when the indoor space is air conditioned, the Heat Recovery Ventilator will help in cooling the incoming fresh air with the stale air that is being exhausted.

All components are UL listed. CONTROLS • Lighted power switch • 3 speed blower control -models 700, 1200 • 5 speed blower control -model 900 • Defrost light indicates when defrost occurs. This is automatic when outside condition drops below 23‘F (-5*C) • Low voltage (24 VAC) strip for external fan speed override to "HIGH" FAN DEFROST The Models 700FD, 900FD and 1200FD are equipped with an electronically controlled fan defrost system to remove frost that collects on the warm air side of the aluminum heat transfer surfaces of the heat exchanger core. When the outside air temperature drops below 23'F (-5°C), a defrost timer is activated which provides for an automatic defrost cycle every 17 minutes. During the automatic defrost cycle the fresh air supply is shut off for approximately 4.5 minutes while the exhaust fan continues to operate. This allows warm inside air to flow over the heat exchanger core melting any frost accumulation. After the defrost period, the fresh air supply fan automatically returns to the normal speed and fresh outside air continues to be drawn into the bu...
