Why Time Delay Relays Matter
Time delay relays are essential components in HVAC control circuits. By introducing a controlled delay between switching events, they prevent simultaneous energization of multiple loads, reduce inrush current, and protect sensitive components from premature wear. Using a genuine Trane replacement like the RLY3167 ensures your system operates exactly as designed.
