The Warren Technology CRR8-9 is an AC to DC rectifier with a built-in 9-second time delay for HVAC electric heat and relay control applications. It is designed to convert AC control voltage to DC while adding a short delay before relay operation, helping support proper sequencing in compatible electric heat systems.
This rectifier is commonly used with Warren electric heat relay setups and is intended for use with T92P7D22-28 relays. It is also referenced for WON electric heat module applications, including compatible Unico M-Series, V-Series, iSeries, and U-Series systems.
