Carrier HF660007 Enthalpy Control 326058-757 The Weil McLain 383-500-619 Ignition

The Weil McLain 383-500-619 Ignition Cable Kit is a critical field-service assembly required to maintain the combustion integrity of Ultra Gas Boilers and Ultra Commercial Boilers

you know that a leaking valve stem can compromise an entire hydronic or steam system's efficiency

providing a seamless fit and electrical integration

providing a seamless cut-out at 130°F and a vertical cut-in at 100°F

It features a high-reliability plug-and-play connection to minimize intermittent resistive imbalance—a common cause of nuisance Lockout-Failure codes

Carrier HF660007 Enthalpy Control 326058-757 The Weil McLain 383-500-619 IgnitionThe Carrier HF660007 Enthalpy Control with integrated sensor is the direct OEM replacement for the obsolete HH57AC077. Engineered for 24 VAC commercial economizer systems, this high precision HVAG enthalpy controller monitors both latent and sensible heat to optimize outside air intake. By calculating the total heat content of the air rather than just dry bulb temperature, the HF660007 ensures the economizer only utilizes outdoor air when it is truly
