Need your help - Thermostat


Need your help - Thermostat
I have an old dial honeywell thermostat. I bought a LUX TX9000TS .

In the old thermostat their are 4 wires:

Green wire goes to G
White wire goes to W
Red Wire goes to R
Blue wire goes to Y


The new thermostat (LUX) here are the wiring diagrams

W Y G B O RC RH C


2 Questions:
1.Where would the Blue wire go? I'm told mixed answers..some say I don't need the Blue wire because the new thermostat works with battery,
others have said copy what what was done before. ...meaning Blue wire in Y of the new thermostat

2Also the old thermostat just said RED wire into R
Where would the Red wire go in the new one RC or RH?



I have a furnace and air condition.

you will need a short u shaped wire you can cut a small paper clip this will be your jumper wire this will conect the red wire to rc and rh the blue wire will need to go back to y hook the rest of the wires up the same way they were on your old tstat if you need a common wire you will have to open up your furnace and see if theres a extra wire but if you have a battery type t stat you shold be fine with out the common wire

Most t/stats come with a jumper wire for the connection between RH & RC, some use jumper tabs like a computer board does. Check the instructions. IMO I wouldn't use a piece of a paper clip if it's not insulated...you never know, you might short something out...probably not, but you never know.

If you open up a honeywell pro 6000 t-stat you will find a u shaped wire from r to rc that imo looks like a section of paper clip this is factory installed and not insulated

Just some additional info. Blue wire will probably turn on your condenser unit outside attach that to Y. R in your case has to go to both Rc and Rh since you will be requesting both heat and cool...cut a small piece off the red wire, strip the ends and use it as a jumper.
