Hello, I got a notice that you want a phone call, we can work in this dialog box for the amount of your deposit, or I can call, but thats a $25 extra.
OK, it is unusual that any thermostat shows W1- O/B under the same screw terminal... those are generally different terminals. Can you verify that is actually the case on your old thermostat?
when checking basic function on a thermostat set to extremes, for instance when checking cooling, set it to 60F
See page 24, heat pump wiring, is that the terminal strip on your new thermostat?
This is a battery operated thermostat, you do not need the C wire, cut the bare copper tip of the wire off, double the blue wire over, and tape it to itself and poke the taped end back into the hole in the wall.
The other connections are
Red wire to R
White to W1
Orange to O?B
Green to G
Yellow to Y
White to W2
If the system cools when you set it to head we have to go into the programming and reverse the function of O/B
If the system cools when you set it to heaT we have to go into the programming and reverse the function of O/B
my mistake, put white in W2
Tell me if the system was working when you had the old thermostat in place OR if the system was not working and you assumed that the thermostat was bad and are replacing it?
Did you turn off power to the furnace before changing the thermostat? if not, they you probably blew the 3 amp fuse that most air handlers have fit into their printed circuit card.. its an automotive type dual spade terminal type
Locate the thermostat wires where they attach to the printed circuit card, and measure the voltage between the R and C terminals... it should read 24v, if not look for a fuse in that circuit
Sometimes an electrician marks the breakers AC that serve the outside unit ONLY, but not the air handler which is where the 24volts comes from that operates the controls
Do the voltage check between R and C in the air handler at the thermostat wiring terminal strip
Use a multi meter, $30 type will work.
The cheaper ones can be dangerous
Hardware store or big box store electrical dept,
I will hold the question open for you until you get back with a multi meter,
if you need instructions go to youtube and search box 'multimeter' for a few dozen tutorials
I am in all day tomorrow as well, starting at 7 am
Good idea, I will see you monday as needed.
I will be in all day 7am to 9pm mostly
buy 3 extra fuses in case you need them
Its time to locate the 'Finish and Rate' link and click on it, the company only pays me for my time expenses if you rate...I will appreciate that very much. thanks!
