Time Delay Relays

We sell several air conditioner, heat pump time delay relays. The American Standard, Trane RLY02807 controls the air handler fan on off cycle. The Bryant, Carrier HN67ZZ001 time delay relay controls the outdoor condensing unit compressor on off cycle. FYI: An air conditioner should be allowed a minimum of 3 to 5 minutes between cycles. The Universal TDOM, Time Delay on Make relay allows you to protect your outdoor air conditioner condensing unit by allowing you to set a time from .03 to 10 minutes before it will allow the compressor to come on. The TDOM protects the compressor from damage if you have a situations where you have storms that cause the power to go off on on, or if you have children or someone who short-cycles the air conditioner or heat pump.
