LF Inexpencive temp controller........
 

Hey Guy's & Gal's,

I am looking for a very inexpensive controller to control 1 heater & 1 cooling fan to keep the temp stable in my 8 footer. I have been thinking of a chiller but can't afford one atm. Let me know what you have or seen.

Ive used an aqua controller JR before for this same reason.
Works very well be it a fan or air-conditioner pointed at tank.
The fan created too much humidity.

Ranco popular, can have a heater and fan plugged in, can also get pre-wired

How do you hook up a heater and a fan to this controller, could not find an info on this.

Maybe try this...? My heater is set at 80 degrees. On my tank I have two fans, one is a 4-fan strip, and the other is a small but powerful Honeywell table top fan. The Honeywell is always on high, and brings fresh air from the living room onto the sump. The fan strip is mounted on the edge of the sump, and is on the same timer as the lights. My tank is considerably smaller than yours, but this setup keeps my tank at 80 at night and 82 during the day. I would like to keep it under 80, but if I set my heater to 78 the temperature will fall to 78 at night, but still go up to 82 during the day, so i keep the swing smaller by setting the heater a tad higher.

The way I see it, using a temperature controller to control a fan is a waste of money. You know the tank will get warm when the lights come on, so why not put the fan on the same timer the lights are on? Also, the fan will not likely cool the tank too much, and if it does your heater will take up little electricity.

sorry the 211000 is the 2 stage

The Ranco ETC-211000 is identical to the Ranco ETC-111000 except that this unit is 2 stage, and has 2 relays to control both heating and cooling at the same time or two heating or cooling stages. (The output relay NC and NO ratings are also different than the single stage control).

This will not work on my tank as the light's are on 4 different timer's and I have not run a heater on this tank AT ALL since it has been up and running. With all the pump's for return, closed loop, 2 skimmers with feed pump's and a pump for my NP pellet's my temp never got below 78 or above 81 until the summer heat and the AC in my house does not affect the room the tank is in as much as the rest of the house.

This is what I am looking for or some thing similar.

Whatever you do, do not get an Aquamedic Biotherm Controller. I dont think they make them anymore but there are probably some used ones kicking around. I bought several a few years ago and they have all caused me problems. Garbage.

For $100 plus shipping I can sell you my 2 month old pinpoint 2 stage temp comtroller.
I upgraded to GHL when my system grew.
