Well DaveK, your point is well taken so without getting into the same old opiniated middle of the road approach let me simply state here that for those that just add a bunch of fans i totally agree it is a mis conception, however, for a system that is heat sensitive with approx. 20 items that generate heat, and 1400 watts of light in a light hood (enclosed), controlled circulation and controled exhaust are of the most important issue as is noise level. who wants fans timmed to come on if not needed? timmers do not take into account the systems need for cooling but, just to run at certain times. So although i do agree with you in concept as you stated it, this thread was originally started based on a not so middle of the road system design, in a location where noise is of the utmost importance, and in a location that may from time to time require extrodinary air movement but not all the time or at set times, so, a method for fan control and light control for the purpose of controlling temp is needed. now once the basic need is identified and the environment is analysed, then the equipment is located that will do the job with the least mantinence hence the aquacontroller jr. does just that. as you know lights can be set timmed on/off and can be programed to turn off if canopy overheats, a protection that some consider very important. some have thousands of dollars invested into their systems and so extrodinary measures are sometimes taken to protect the investment. well anyway just my two cents worth and just another opinion. thanks DaveK for the feed back on the posted design and thanks for your posted thoughts on this thread they are all appreciated and respected by this hobbist even though I may not totally agree with you. good fishing to all and please post your thoughts.
