Will it work on older units and are there detailled installation directions?

Should work. Installed this on a 20+ year old gas furnace with electric A/C. Lots of detailed instructions.

Mine worked, model should not make a difference. Just get installation information and follow it.

You need to bring the item up online for this model or consult with expert. See manual references. It has worked great on all elementary functions.

I suggest searching google putting model number and manual and you should get results, also sometimes YouTube have instruction videos. You should have got a manual with the unit.

I would email the seller and ask there Rly nice and know what there product supports. I don't think this unit alone will do it there maybe another add on you'll have to buy. If I find my manual I'll replay with what I find

I believe it is compatable, most of the older units seem to use the same kit

Yes it will. If your unit is older then 1993 you can also use their 890max. Its a keychain version. If you need help with the programing please reach out to us. Thanks...Matty

I can't remember if it came with then or if I printed them out online. I know I read that you can find the install instructions online though. Just search for them and you should find it.

The package will list which ones it will work on and provides the instructions for those it can. I found it locally in my hardware store but they were pretty expensive and found a better price on amazon.

For REALLY technical questions, I suggest that you download the user manual online for the particular model you are interested in. Then, call the SERVICE phone, here in the USA. I found that, when my unit was installed, we could call that phone number and get all our questions answered. They were very helpful on the phone. Amateurs (like me) would not give you as good assistance. Also, the user manual may have the specifications listed that you are looking for.

Refer to the manufacturers owners manual online and get the model and serial numbers found on the unit to verify. It worked for me.
