SP-RNC120D
THERMALLY CONDUCTIVE, PATENTED ALUMINUM CORE
The cross-flow heat recovery core transfers heat between the two airstreams.
It is easily removed for cleaning or service.
MOTORS AND BLOWERS
Each air stream has an independent motorized impeller. 2 speed fan operation.
FILTERS
Washable air filters in exhaust and supply air streams.
MOUNTING THE HRV
Four threaded inserts at corners of case designed to accept four reinforced polyester straps that are supplied
with the unit.
DEFROST
Recirculating damper defrost system.
CASE
Twenty gauge prepainted galvanized steel (G60) for superior corrosion resistance. Insulated to prevent
exterior condensation. Drain connections- 1/2" (12 mm) OD.
DUCT CONNECTIONS
5” duct connections.
WEIGHT 42 lbs. (19 kg.) SHIPPING WEIGHT 45 lbs. (20.5 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.
OPTIONAL MAIN CONTROLS (only one main control can be installed on the system)
99-116 Dehumidistat Ventilation Control - Dehumidistat Dial, ON/OFF Switch and
LOW/HIGH Switch (3 wire) 20 gauge wire (min.) 100' length (max.)
99-2040 20/40 ON/OFF Dehumidistat - Dehumidistat Dial, ON/OFF Switch and 20/40 Switch.
The 20/40 Switch will toggle from continuous low speed ventilation to intermittent low
speed ventilation of 20 minutes fan ON and 40 minutes fan OFF. (4 wire) 20 gauge wire
(min.) 100' length (max.)
99-RECIRC Recirculation Control - Dehumidistat Dial, ON/OFF Switch and Recirculation Switch.
The Recirculation Switch will toggle from continuous low speed ventilation to continuous
low speed recirculation. (4 wire) 20 gauge wire (min.) 100' length (max.)
99-130 Remote Dehumidistat - Dehumidistat Dial only. (2 wire) 20 gauge wire (min.) 100'
length (max.)
OPTIONAL TIMERS
99-132 20 Minute Fan Timer - initiates high speed ventilation for 20 minutes. (3 wire) 20 gauge
wire (min.) 100’ length
99-104 Digital Electronic Timer- initiates high speed ventilation for 20, 40 or 60 minutes, (3
wire) 20 gauge wire (min.) 100' length
99-101 60 Minute Crank Timer - initiates high speed ventilation for up to 60 minutes, (2 wire)
20 gauge wire (min.) 100' length (max.)
