Description says *includes 1x DC 24V Digital Temperature Controller *. Does it come with a temperture sensor ? If no what should be used ?

Mine came with a 1 meter length RTD (resistive) sensor, and operated on 12 Volt DC. These types of controllers should come with sensors, as it would be relatively expensive to have to buy one that is matched and calibrated to the controller.

No. if you use a separate controller, which I do, then it can be easily adjusted to the temperature you want. I use the Ranco ETC-111000-000 Prewired Digital Temperature Controller (ETC-111000-000W) from ETC Supply.. They can also supply an extra length sensor wire and also install heat shrink tubing for underwater use. As far as a automatic timer for the different temperatures, I don't know about that.

I'm not sure what you mean, thermometer? Ours does not have a digital thermometer and nothing on it is digital, but you can purchase one separately. So far we have had no problems with the temps. and have not used any additional thermometers nor thermostats. Sorry I can't help more.

Yes it does. Digital screen displays the temperature and plus n minus buttons to control it.

The temperature sensor is small about 1 inch or less. No extension cable came with mine. I think that it is under the picture of the controller..

Yes, the DS18B20 uses the one-wire protocol, here's a tutorial on how to interface it with the PI: http://learn.adafruit.com/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing/hardware

It is an AC detection unit. It does not measure DC so polarity of the coil is not important.

I also bought this . It only works on a 24 volt dc system. Mine was not advertised to convert from a 12 volt dc source.

The unit is designed to monitor temperature, power, and water. It is not designed to incorporate other sensors. There is only one water sensor included and one input in the controller for the water sensor. I don't know if you could tie additional ones into the line for the control unit. The unit is designed for use in one building although you could conceivably locate the water sensor in one area (within 100' of the control unit), a basement for instance, and install the control unit in a garage to monitor the temperature simultaneously.

Only needs 12 volts for lightning. Will read temperature without the 12 volts.

Yes, definitely has temperature control. There's an analog turner versus a digital representation of the #'s but you can control the settings.

Frankly I dont know as I never use it, And my manual doesnt really go into great detail?, But there is a line that says : "Plug the Red Terminal into the Output to block the DC when you want to test AC Only!. 'Outerwise its a Nice tester and in my opionion its a real steal at this price as i am very well satisfied with mine but again to each his own!. Hope this helps: BEST WISHES!.....

No, just current temperature. It does give lull, peak and average wind readings, which are reset when it's turned off. I doubt the batteries are meant for 24 hr. monitoring.

No it does not, It comes with a micro-controller that has 2 5v leads that will need to be connected to a digital gauge or heads up tuning software.

No. It is a resister thermal device (rtd). It needs another device to convert the thermal resistance to a temperature.

There is a second part that they sell to go with this. It is a thermostatic temperature control. About $18. They should clarify that most people would need both pieces. It has the two inputs and connects directly to the unit. Then you can set a temperature that you want. This setup works very well.

I didn't have a C wire when I installed my thermostat. From what I can figure, the C wire is used for power, and the batteries will kick in when the power goes out. My previous thermostat was programmable with batteries. The batteries lasted a long time in that thermostat.You can set the temperature range where you want and leave it. For some reason, my Vera 3 set up 3 thermostats. 2 are like ghost thermostats, and 1 is the real one. But, I can access and control that thermostat from anywhere. I also set the poling time lower so that it checks the temperature on the thermostat more often. I think I set it at 1/2 hour. I didn't have a C wire when I installed my thermostat.
