American Standard Trane TAYASCT501A Time Delay Kit

Description:

The American Standard / Trane TAYASCT501A Time Delay Kit is an OEM anti-short cycle timer designed to protect air conditioning and heat pump compressors from rapid cycling. Operating on 24 VAC with a 1 Amp maximum switching capacity, this time delay module introduces a fixed 5-minute delay before allowing the compressor to restart after shutdown, helping prevent compressor damage, reduce electrical stress, and extend equipment life. HVAC service technicians use the TAYASCT501A for replacement, retrofit, and preventive maintenance in compatible Trane and American Standard residential and light commercial HVAC systems.

Applications:

The TAYASCT501A time delay kit is designed to prevent short cycling caused by thermostat fluctuations, brief power interruptions, or rapid demand changes. It is commonly installed in Trane and American Standard split-system air conditioners, heat pumps, and condensing units where compressor protection is essential for reliable system operation. The kit is specified as an optional anti-short cycle timer accessory for numerous Trane and American Standard outdoor units.
