57T01-843 BLOWER TIME DELAY RELAY 

## 57T01-843 BLOWER TIME DELAY RELAY 

The 57T01-843 Time Delay Relay is for use in air handlers installed in compressor-run air conditioning and heat pump systems to delay the blower shut-off after the compressor has shut off.  Replaces Trane part numbers D155079P01 and RLY 2807. 

## FEATURES 

- Allows 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.
