This is a very simple inexpensive unit that works by using a bimetal strip to open and close two contacts to make or break the circuit. This bimetal strip bends in one direction as the temperature around it increase and bends in the opposite direction as the temperature around it decreases. The higher the temperature the more it bends. This bimetal strip has a contact point toward one end that matches a similar contact toward the end of the second strip. As the temperature increases (in the attic around the control) the bimetal strip bends toward the second strip and brings the two contact points closer together until they meet thus completing the circuit and turning on the fan. As the temperature decreases (from the fan moving cooler air past the control) that same bimetal strip bends in the opposite direction moving the two contact points apart thus breaking the circuit and turning off the fan. As you turn the temperature adjustment to the left (lower “FAN OFF TEMPERATURE”) the contacts move closer together. As you turn the adjustment to the right (higher “FAN OFF TEMPERATURE”) the contacts move further apart. The more space between the contacts the higher the temperature must be to close the contacts.
Unfortunately the label on the front of the control is misleading in that it states “FAN OFF TEMPERATURE”. The degree readings are also not very accurate. That being said, keep in mind that this is an inexpensive simple control not made to be supper accurate. These controls are mass produced and may have significant variations from one unit to the next. Since this review is already long I won’t list all 72 test results. I will say that with the control on and set to 120 degrees F, I raised the temperature to 150 degrees F and it still didn’t turn off, so much for the “FAN OFF TEMPERATURE”. The important things to note on the unit I tested are as follows. The temperature variance (delta) between when the fan turns on and when it turns off are between 3 to 6 degrees. If I set this unit at 120 degree F the fan will turn on at 85 to 86 degrees F and turn off at 82 to 83 degrees F. It is also important to note that the control should be place in an area toward the center of the space and in the path of the air flow created by the fan. If not you run the risk of the control turning the fan on but not being able to turn it off because there is not sufficient air flow to lower the temperature of the control enough to turn the fan off.
I will install a wall switch to feed power to the control just in case I need to turn if off manually. Attic temperatures here in central NJ can easily go above 120 degrees F in the summer. I’m not sure if this fan will be able to cool the attic enough (down to 80 degrees F) to turn the fan off. If it doesn’t I can always turn it off at the switch.
If you look close at the uncovered turtle in the foreground I've highlighted the "Control" to the thermostat suspended about 8" down in the attic. A added a lever arm to the adjustment screw and use an old bicycle spoke which I taped in position, I've got this setup on both fans, and start the one in the next turtle to go on when the attic gets to 75 deg, and this one just before 80 deg.
With the two fans in the attic temps are running only a few degrees hotter than the OAT, prior to installing these fans the temps would reach as much as 40 degrees higher than OAT. Incidentally, the white tarps are temp control as well, the tarp surface will read about 130 on a 95 degree day, while the shingle will read 160+.
