Heat sequensers

[heatseeker]

My weak point for sure are heat sequencers. It seems that its very hard to match them up on old models. It it possible that there is a universal heat sequencer that can take the place of the multiple ones in units or am I just not aware of the right * Any feedback would be helpful.

honeywell used to have one that was about 4 inches square with 3 contacts plus an aux contact to daisy chain another one if you needed it. i don't know if they still make that or not. otherwise, i think most shelf sequencers will work on most applications.

Yea it was a fan thermo disk. fan stack relay of some sort, when the unit gets hot it opens the 24v line and shuts the fan off. I don't know why but they drive me crazy and are hard to figure out.
