possible to wire a fan controller on a timer?

[canadiancracker]

i am not on location and am having nighttime temp problems.. they are dropping to 10-12c. and probly lower once the -30c days come around...

my question is. is it possible to wire a fan speed controller to a timer or tempstat to it turns down the speed of the exaust turbine when the lights go out?

i have 2 can 100's venting 9k of lighting, 1 can and turbine is on a tempstat, over 75deg it turns on, and the other runs 24\7 to avoid the sweet smell of mj from escaping the room..

if it can turn the speed down on the constantly running turbine when the lights go off would be perfect..

anyone who has done this or could explain the wiring possiblity of this please.

THANKS in advance.
happy gardening

NC = Normally Closed (Contacts are closed as default)

I'll try to do a diagram, but i'm a bit slow with drawings and I think i'll have to go and double check how mine is wired, to make sure I get the drawing correct, I did mine this way a couple of days ago, my memory's not good in the short term though

ps. I can also make the addition of another relay, which will then switch from Variac, thermostat or timer, but I still dunno how to just post the image.

Get one of the Cap controller DNC-e (I think, forget the exact model number).

Its $80 at grow stores. You can set daytime and nightime temps, and it is a fanspeed controller. So at night it slows your fans down when the temp drops below your set perameter, and during day speeds them up.

Just got one, and for $80 it will prob save that much in electricity alone by not having all those intake and exhaust fans running so hard half the time.

$80 isn't bad at all for a plug-n-go solution from the store. It's gotta be Triac-based, though, since Variacs are more expensive/much larger.
