Hi guys,
Am going to replace the current Cam Stat Fan limit on my old furnace coleman with a honey well 8 ". Could you specify the diagram for wiring on honeywell.
Thanks for your prompt answers

It depends upon the cam stat. Some are special and you cannot use a Honeywell to replace it with.

Post Exact model of the Cam Stat and post the exact model of the Honeywell.

I will see if I can find the wiring diagrams for the cam stat to see if it will work.

NOTE many furnace manufactures require the cam stat style for the blower and limit control section to work properly. Just a warning.

Hi HVAC 1000Thanks so much for your prompt answer

Here are the model no for Cam Stat FALTS F7C-05T-120.A and on two terminals you can see 24VAC HTR which is going to be replaced with Honeywell L4064B, L,R & W
Would appreciate a wiring diagram pictorial or schematic whatever and thanks again chow

Hvac 1000 thanks again
Then what about the two wires 24vac which terminals do they sit on the honeywell please and thks . Well the other four terminals can be figured out though. My guessestimate is that those two wires 24vac can sit on the two terminals in the middle of honeywell fan limit as heat strip am i right??

The reason I left this up to you was the wiring is VERY critical if you have a mix of 24 volt and 120 volt wiring in use on your furnace. I have no idea what you have but if you do have a low and high voltage mix in use you will have to remove/break the tab as shown in the instructions.

Terminals 5 and 6 on the camstat as Shown on the wiring diagram I provided you are for the low voltage/limit wires. 2 and 4 are for the fan switch on the camstat.

The Honeywell Fan side which is left on the diagram I provided you will use 2 and 4 wires of the cam stat and the limit which is right side of the Honeywell will be used for the 5 and 6 terminals on the that were on the camstat. If low voltage high voltage mix you have to remove/break the tab as shown in the Honeywell diagram.

I hope this helps.
