Thermostat issue, need help

OK, here is the issue I have. I have two zones for my heat/ac. I have an oil boiler, an a/c unit outside and what i believe to be hydro heat as well (there are copper pipes that run through the forced air portion of the blower).

One zone (main floor) has a nice programmable LUX thermostat. The upstairs zone has an old school dial thermostat that is obviously not programmable, causing over-usage or heat and/or A/C.

I opened up the thermostat upstairs and it has two main wires coming out of the wall. Attached to the thermostat were 3 wires, R, Y, W. The W and Y come from 1 larger wire and the R comes from the 2nd larger wire with two open wires taped off.

I am not sure how to connect the new LUX programmable thermostat. The 3 wires that were being utilized previously are labeled. The other 2 are not labeled. They are white and black in color. The R was red in color.

SO, I would like some assistance if anyone can help in trying to install this 2nd thermostat. I would like it if the upstairs zone was a completely separate zone. Right now i believe when you turn off the thermostat downstairs, it turns off the ability to use the "dial" thermostat upstairs.

If you want to find out if there are wires from the downstairs thermostat, to the upstairs, you are going to have to do a continuity test, or get a fox & hound set.
