Wiring up a "fan in a can" to turn on with power venter

I have a fresh air duct from the outside that I would like to add an inline booster fan too that would turn on and off with the power venter (sort of like a cas-3 combustion can. Can I tie the wiring in with the field controls ck43 power venter control? See link below for control and wiring diag:


I was going to tie the booster fan to the power venter leads with pigtails...can this ck43 control handle the extra load on terminals N and M? I cant find anything that says how many amps this control can handle.

I would imagine it would be fine as the ck43 control is used on power venters that are much larger than mine such as a swg14 which is good for boilers up to 3,000,000 btus (thus a bigger fan with a much larger load). I have a swg 4 that is good for 170,000 btus.

I don't see why your idea wouldn't work. I do suggest talking with Field regarding amperage.
