.. I was wondering if anyone could help me figure out a thermasts+hydrostat setup.. I have 2 units I got from a friend there nice Johnston controls units that are not cheap and apparently very accurate. I want to have a system to turn on my exhaust fan/filter when temps go up and to turn off the fan once the temps go down.I am pretty sure this is the way they are currently wired up now. But I want to be able to have the co2 solenoid to come on when the fan is off. I am sure you under stand what I am talking about.
will I need a relay or something to make this work?
the two units are already wired together but I think its just to turn the fan off if either the humidity or temp gets to high, I dont think the current wiring will allow me to ad a co2 solenoid to come on when the fan is off..
is this a very difficult task. I do know some basic electrical home wiring and have a good level of "electrical tinkering ability "
what else will I need to make these two units to do what I want
