If i set this to 80 degrees-does this mean my vent fan runs till it get 80 in my garage? The one I have now (which is new) runs when set at 80 and

cuts off as the temperature rises- which seems backwards to me.
Asked by: dissapointed
If you set it to 80 degrees the fan should turn on when it warms to 80 and remain on until it drops below 80. If your unit is doing opposite I would check and see if it is wired correctly. I have 3 of them and have never experienced that issue. Try setting it to 90 and see if that helps. Maybe 80 isn't "extreme" enough for it.

I would like to hook 3 small attic roof vent fans to one of these PT6 thermostats. Each fan's running amps is 1.35 amps

at 120 volts, The motors are capacitor start type.. Is this OK?
Asked by: Carl76
If you wanted to use a single one of these to run multiple fans you would want it to drive a 120v contactor(relay) to operate the fans system.

Would thermostat work on a solar attic fan or does it need 120 VAC?

Asked by: Carlos
Yes, it will work on AC o DC. A thermostat like this is merely a set of contacts that close due to a bi-metalic disc moving with to the amount of heat it gets, based on your setting. The contacts don't care if it has AC or DC connected to them, as long as you don't exceed the amperage rating on those contacts. That is 15amps on this thermostat. LOW voltage DC does often raise the amps significantly over 120vAC, so be sure you don't go over 15amp.

what does prewired mean?

Your add says the thermostat is prewired for easy instalation- does that mean it is or has a female socket you plug into??
Asked by: johnny
Two black wires are provided with soldered connections inside the thermostat unit. You only need to connect one of the black wires to black wire of the power source and connect the other black wire to the black wire powering the fan motor. The white wire from the power source and the white wire from the fan motor need to be connected. There is a ground screw provided for grounding from the power source. There is a wiring diagram printed on the unit itself.

I am using this switch in conjunction with a 6" room to room wall fan to move radiant heat from a furnace room into the colder part of my basement. It is working very well for this purpose. The only thing I was a bit disappointed with is the mechanics of the thermostat. It has a 2-4 degree swing on the setting. Since it is designed for attic use this range is not bad but for my use I would like to see the setting be more accurate.

Rated 1 out of 5 by from thermostat I have installed the thermostat on my attic fan. After many trips to the attic either to adjust the unit to make the fan come on or off I have concluded that the control does not work. Its not the fault of HD.

Simple wire and ground connections for single attic fan install. Thermostat was installed during winter months - so no review can be made with respect to performance.

Rated 3 out of 5 by from Does the job, but has accuracy issues. Thermostat is a basic bimetal, that make/break contacts based on temperature. The instructions may not be great but I found installation self explanatory. There are 2 wires to the thermostat that make/break the connection to the load. The motor's neutral goes straight to the power neutral, both wires are white in most cases. Ground goes to the green grounding screw. The thermostat wires hook up like an ordinary light switch. The thermostat works but I found mine to be 10-15 degrees off. With a 110 setting the thermostat kicks the fan on @ 120-125. Measure actual attic temperature and set thermostat accordingly. Temperature "spread" doesn't seem to be quite enough as the fan cycles on/off after the sun goes down. I'd rather see the thermostat have a larger "spread" between on and off, perhaps 10 to 20 degrees.

Rated 4 out of 5 by from Adequate Bought this to go with replacement motor. Seems cheap but it was exactly like the original. Came set on 105* and that seems to be close. I tried to test the thermostat in use with a thermometer but soon tired of that. After installing I walked up to attic and the motor was running. The thermometer read 113*. Later returned to attic and ventilator was still running, temperature was 90*. As I turned to leave ventilator stopped running. Generally, the ventilator kicks on in the morning around 10-11 o'clock and off about the time the roof is shaded, 7 o'clock or so. Physically feels about right, the attic is cooler.

Rated 4 out of 5 by from Had to have it. Home Depot sells attic fans in the store. But for some reason not the regulator thermostat. So it was purchased on line. Welcome to big-box logic. Made a simple project turn into something for two weekends waiting on parts.
