During the air conditioning season, the HRV will help cool the incoming fresh air with the cooler stale exhausting air. RNC Electronics RNC electronics offers standard 2-speed operation of low/high. There is also an installer selectable 2-speed operation of medium low/high (refer to "Increasing Low Speed to Medium Low" in this manual). The RNC circuit board also includes an interlock relay which is used to Interlock the HRV to an Air Handler/Furnace. Refer to "Interlocking HRV Operation to an Air Handler/Furnace Blower" in this manual. We recommend using one of the Optional Main Controls (refer to "Remote Control Devices" in this manual) for normal operation.

It is easily removed for cleaning or service. MOTORS AND BLOWERS Each air stream has one centrifugal blower driven by a common PSC motor. 2 speed fan operation. FILTERS Washable air filters in exhaust and supply air streams. MOUNTING THE HRV Four threaded inserts at corners of the cabinet designed to accept PVC reinforced polyester straps that are supplied with the unit. DEFROST Recirculating defrost system. CASE Twenty gauge prepainted galvanized steel (G60) for superior corrosion resistance. Insulated to prevent exterior condensation. Drain connections 2 -1/2" (12 mm) OD. WEIGHT 52 lbs. (23.6 kg) Shipping Weight 56 lbs. (25.4 kg) CONTROLS -HRV System Control HRV defaults to LOW SPEED when plugged in. HIGH SPEED option is accessible by connecting remote controls to designated terminals inside electrical box of HRV. Standard LOW SPEED SETTING can be increased to medium low. Off (Standby)/Low or OFF/HIGH speed operation is also available.
