I have just installed this digital them. i know i have it hooked up right i have done many in the past and even looked at the directions. There is an override switch like a light switch that i can shut it off with but the heater/ac continues to run no matter what temp i set it at. Any help would be nice thanks

Yes you can add another thermostat in parallel. I can see the logic, if one stops working, ie fails to turn on, the other will drive the system.
I have 2 wireless thermostats, and 4 wired thermostats, driving my system, one is remotely controlled by 'phone, meaning I can set the others to keep the home warm at a lower temperature, and switch the whole system to a higher temperature when starting home, it normally takes 24 to 36 hours to get my home back to the normal 22C/72F. My heating is always on 24/365.
Need to know if you have central air as well. If you don't, then hook up the Red to R, White to W. you @ least have heat. any other wires you hook up will be dependent on what type of system you have ie boiler, forced air, etc.
One wire is "IN" the other is "OUT" A Thermostat works by "Breaking" the "Phase" line. It is just that simple. You usually have a pair of wires that connects, on the "Hot" side, to the always power ON line, & neutral. The Circuit, or Load, on the "Cold" side, has a a pair of contacts that open & close depending on Thermostat, in series with that conductor.

which type of T-Stat is it ? most standard t-stats have it built in that the temperature range is only a half a degree, it may seem like its running alot more, but in actuality it is maintaining better home comfort as it is not running as long as the old bimetal t-stats which would have a range of anywhere from 2-5 degrees which would cause the furnace to run alot longer, use more energy, use more fuel, and you would notice a definate change in the house temperture before it would come on or shut off, your t-stat seems to be working properly, and it will save you money, remeber also to change those filters !!!
What kind of system do you have (furnace with heatcool, heat pum or boiler )? Is there a themostat there now. How many wires does it have. If you have a furnace and you have heat&cooling install red wire to r on thermostat white wire to w and green wire to g. The g wire is usually for the fan. If there is a thermostat there now the old one should have the same letters on the back by where the wires hook up. The color of the might be diffrent than the ones i used for an idea.
On paul 306, I don't have any info on you're system, but the old thermostat that has the smaller wires with the colors you described is a low voltage (24volt) controls. The new one you purchased sounds like it is for a system that is made for line voltage (120 volts or more) connecting this to the unit may have bad results. This also may apply to GUEST. COACOOCHEE, the white and black coming into the box is the line, even though white should not be used for line, the connections for the other side of the thermostat is the load. The new thermostat you have be a single pole break as opposed to the old one may be a double pole. You should have a meter to check the voltage coming into the box, it may be 120 or 220 depending on what you have. Without any more info I cant be sure, but you may be able to connect the black wires to the switch and the white together. But it would be wise to test with a meter to be sure before doing this.
