FAQ:

Q: How does the 1K relay work on a burner?

A: The 1K relay remains powered through its 1K1 contact, and the burner runs. On flame failure, cad cell resistan ce increases until the triac is energized. The safety switch heats until the bimetal warps enough to break the circuit and stop the burner. The primary control must be reset before the burner can be restarted.

Q: How do Honeywell furnace cad cell controls work?

A: In fact, Honeywell cad cell controls are actually checked out on a working furnace in the factory. Cad cells respond faster to flame than stack relays because the visual detector works almost immediately. Except in the R8991, the cad cell location is determined in the factory, so that one-of-a- kind field installations are not necessary.

Q: What is an r8228 relay used for?

A: For installing R4222, R8222 and R4228, R8228 relays on junction boxes. Provide heavy duty switching for refrigeration and air conditioning equipment, appliances, vending machines and similar applications. Use in compressor-run air conditioning, heat pump systems and heating-cooling systems.

Q: What are the different types of auxiliary controls on a furnace?

A: Other auxiliary controls that ar e available include fan controls, zone valves, air cleaner or humidifier controls, time delay controls, and additional relays. Fig. 9. Oil heating system controls. One more component worth mentioning is the V4046 Oil Valve.
