  • The SAS can also be used as a Return Air sensor on the HK2000 Economy Control System and the UZC4 Zone Control system
  • When being used to monitor return air, EWC recommends mounting the RAS in the return plenum, downstream from the bypass damper between the bypass and the air handler
  • This is done to ensure the air being sensed is a proper mix of bypassed air and return air
  • The “SAS” box is constructed of UV stabilized poly carbonate plastic with a seamless aluminum tube & plate assembly
  • The vastly improved thermistor is vacuum potted into a separate stainless steel sleeve, which is then inserted into the tube, creating the temperature probe assembly
  • Vacuum potting prevents moisture from penetrating and affecting the thermistor
  • The unique construction provides a thermal barrier between the temperature probe and the duct work allowing precise air temperature measurements
  • Dimensions: 2 x 2 x 1 in
  • Insertion Length: 5-1/2 in
