A timer is actually a good idea. Those humidistats typically connect to the furnace in such a way the humdifier or exhaust fan will only turn on when the furnace fan is powered by your thermostat. In addition many humidifiers also have a function to only activate when warm air is being pumped through the furnace. So my point is those humidistats aren't really designed to work alone, the furnace typically also contributes to the control which prevents them from turning things on and off too rapidly.
So if it were me I'd wire in a timer to control the duty cycle, this wouldn't eliminate the purpose of the humidistat it simply mimics it's designed purpose. You could also just wire it into the furnace so it only turns on when the furnace turns on which would eliminate any negative pressure effects, not that there would be. An alternative would be a different controller, something like this is probably better suited to the application: http://www.canadiantire.ca/AST/brows....jsp?locale=en Last edited by sphelps; 11-03-2011 at 04:01 PM.

the way i see it using a timer would be adding the variance that the humidistat lacks. i wouldn't set the thing to be powered a couple times a day... i'd have the power to it every 30 min or hour.

I would think if the timing of the fan coming on and off is a bother, you could perhaps try for a quieter fan and save yourself all the other troubles your experiencing.

The fan is not noisy I was thinking more about prolonging the life of it. It was only $40 tho... maybe I'll allow it to maintain a constant humidity as is and just replace the guts if she fries. Time will tell I guess.

Yeah good call that's what I'll do. It's doing it's job perfectly as is. Still feels humid in there relative to the rest of the house... as soon as you exit the fishroom and you're in front of the tank you get that awesome calgary dry-air-nosebleed feeling again.

You could look at getting an IAQ digital humidistat. Search on google or Amazon for digital IAQ. I think Honeywell makes a bunch. The digital ones should do what you want I think.
