The ST82 Fan Manager is for use in air conditioning and heat pump systems to delay the blower shut-off after the compressor has shut off. This delay allows the residual cooled air to be blown into the controlled space, increasing the efficiency of the system in cooling. Depending on electrical hookup in a heat pump system, delay of blower shut-off could also occur in heating. ST82B includes R8222B Relay with spdt switching; ST82D includes R8222D Relay with dpdt switching. ST82 has 80 ( 10) second delay timing. Ambient temperature range is -20 F to 150 F [-29 C to 65 C]. Underwriters Laboratories Inc. listed; Canadian Standards Association certified.
