Hello,


I have just purchased an electronic programmable thermostat. The old
one that I had was the old dial type. Anyway, here is the problem... I
installed it and for some reason every once in a while both the heater
and the air conditioner will come on. This is a dangerous situation
since I think that it will cause carbon monoxide. I'm a newbe with
electronics and I'm not sure what to do. I have installed two separate
electronic models thinking that it was the thermostat.


Here is my setup:


Gas Heater / electric air conditioner / unknown models.


5 wires coming from the wall. I think that they are white, yellow,
blue, red, and BROWN????


The previous model has been thrown away, but I do remember a small
like jumper type wire connecting two of the pins inside of the
thermostat.I don't know what the brown wire is though.



Any help would be greatly appreciated.
