Electronic Replacement for A.O. Smith Burkay "Thermal Balancer"?

Member Posts: 17,358
Looking for a particular type of delay-on-break relay that will mount in a standard knockout and keep a circulator running to purge heat out of a boiler. The Burkay uses a relay of this type (A.O.S. part# 9005908205, old # 98190, made by Eaton or Invensys under that company's part# 31CLVD) but it appears to be mechanical; does anyone know of a newer type of relay that will do the same thing?
Thanks in advance.

Ranco ETC controller by ETCsupply.com
hey steamhead,
Sounds like you need an Ranco ETC controller- here's what its got.- Wide temperature range (-30F to 220F) and differential adjustment (1F to 30F)
- Accepts 120/208/240 volt input.
- Relay controlled so it can control 0 to 240 volts.
- Output can be isolated from the input voltage that powers the controller (each stage in 2 stage units can be isolated.
- User selectable heating/cooling modes for use in hundreds of applications.
- Replaces most electromechanical and electronic temperature controls.
Its pretty much perfect for setting up a heat purge for any system. . I like it as its based on water temp not a timer like most delays. Just make sure its set to cooling mode so it makes on temp rise. The temp sensing wire straps to the supply and the controller can sit anywhere. Works great. Once the supply temp drops to whatever temp you have set for it shuts off.
