My system has two additional wires for "RAS," Return Air Sensor. What should I do with them when installing the Venstar unit?

You need to contact the Venstar tech support. I had no luck with either them or the company that sold it to me http://www.hvacpw.com/terms.asp for tech support. Look in the user manual for the tech support support email, that's all there is, and they do not follow up. Good luck.

You can mount the 2 sensors with plastic tie straps or the screw type radiator hose clamps.

I received a few extra wires with my purchase. Did you not receive extras with yours? I would contact the seller, directly, and inquire with them about some extra wires.

These sensors should work with units that have 2 wire connections to the main system board. They are quite simple and work very well. You should not have any trouble replacing your old, damaged, non-working sensors.

If you have a 4 wire system you simply install a jumper wire at the furnace. You will lose the ability to run " fan only " from the thermostat. FAQs on venstar website describe wire hookup.

Gary, Have you read the installation instructions? If you did not get any with the unit then go here and down load the 2 documents. The first is the installation documents and the best and the information that your after is on the second page of this document in the top left, the second is how you put it in your system. http://www.winegard.com/sensarpro/ JR Wright

you will need two that will be located before the converter and two that will be located after the converter. all four may be the same part# or the front sensors may have a different part# from the rear sensors. depends on the length of the wire coming from the sensor. that's what i usually see. hope this helps.

You are better off replacing both and this kit will do it. I had the same issue in which I only needed one. But you are hard pressed to find just one sensor that will work. Save yourself the headache and use a kit.

I don't know a specific answer to your question, however when I was installing mine, I had a wire that I didn't know what to do with. I contacted RCS (check their web site) and received prompt and courteous support. My thermostat works great!

Hi Rebecca, you will need a 12mm socket with an extender. Just unbolt the old sensor from the engine block unhook the tie down holding the wire and then unplug it. Fairly easy to do, if you can remove a sparkplug you should easily be able to do this. Karen

You don't. I returned this tstat because when I received it, I found the circuit board didn't have a floor sensor spot. It is often shown with radiant floors, on Amazon, something which I gave Amazon feedback about, but Amazon basically told me that if people buy the two together, even if it is wrong, their system will group it. The way this one checks temp is by an air temp sensor built into the unit, so your floor can get baking hot, before it really does much to the air, which means while it CAN work, it CANNOT work well or efficiently for radiant. Options include ones like Sunstat which makes a digital and a analog version. I have the digital, and it works great. Secondly...when installing a floor sensor (before you set your tiles), install 2 spaced several feet apart. Run both wire leads to the thermostat, label one as backup, and don't connect it, and use the other. If you ever have to replace a tile and accidentally cut the sensor wire, it is useless...and having a backup sensor already run, makes switching the wiring a MUCH cheaper and faster solution, than breaking up a row of tiles in order to lay a new sensor under the tile again. I got a second sensor wire for around 10 bucks, and (knock on wood) have not needed to use it. Also, if your sensor wire comes from the manufacturer with a short or break in it, because of the time you wait for the floor to cure before activating it, you won't find out about a problem until after you have done all the work...then having a problem can be pretty frustrating.

Hi Patrick no, the unit is more for replacement i used my existing wiring and air tube. hope this helps ?

This is a door or window sensor. It is not stand alone it was added to my existing system.

If you still have your air box it won't be a problem, if you don't, take a look at this - http://www.naxja.org/forum/showthread.php?t=1026480

No, just received my pair in a box with the wiring. Had the lame air pillows in the box, but plenty of room to move around. The sensors are just in little plastic bags. I was changing them as a preventive maintenance, because my 5.3 Intake Manifold gaskets failed. Does anyone know if they can be tested before installing them? I'm paying a mechanic to do the work. Really don't want pay for the job twice, because Amazon does not know how to ship fragile items.

It did mine, I got both sensors and had to splice one of them to make it longer so the connector would reach. I don't remember which one. But that was easy and it works great.

I am going to assume you have a heating and cooling system. That being said, you need to have five wires in your thermostat cable from the furnace unit to the thermostat. Refer to page 46 of the VENSTAR manual - the 5 wire, 1 stage cooling/heating diagram. The color coding is as follows: R(red)=24 volt power; W(white)=heat; Y(yellow)=cooling; G(green) =fan; and blue(for me)=common. This is where the trick is - you must have five wires so that the common can be connected between the furnace and the thermostat. The older systems did not need the "common" because they were not a powered devise. If you don't have five conductors in the thermostat cable then you will need to replace the cable.
