astroboy May 10, 2009 May 10, 2009 I've asked around about this but haven't been able to locate such a thing. I'm looking for a gizmo that has one inlet (110V) and two 110V outlets. One outlet would be connected to my heater, and one to the fans that cool my tank. What I would like is that when the heater is running, the fans turn off. When the heater turns off, the fans turn on...... Does anyone know if such a thing exists, or if a DIY exists to built it yourself? Thanks in advance.....
jason the filter freak May 10, 2009 May 10, 2009 i think you're looking for a dual stage ranco controller
Coral Hind May 10, 2009 May 10, 2009 There are a few ways to do it. One would be to DIY it with an NC relay on the neutral of the heater so when the heater turns itself on, the relay would open the hot wire to the fans. IMHO - I would just go with the dual stage Ranco like Jason mentioned. It will be more then the DIY project but it will have a lot more uses later on. I have been using my Ranco for 10 years now. I did have to replace the temp sensor last year which cost about $3.
