Please give me model on new thermostat and tell me what color wires went where on old. If you have a picture of old would be great
Excellent. While I pull a manual on new thermostat tell me what terminals each of these wires went to (EX Red to R, Green to G, etc)
Can you look in the air handle rand tell me what these wires connect to. Or maybe give me model on old thermostat I might can figure this out. (The biggest issue we have is some older themostats used B as COMMON.
Blue should be going to the O/B terminal if it is connected to blue in outdoor unit.
Here is what is normal:
Red is of course power so goes to R with a jumper to RC
Usually there is a Green to G for the fan
Yellow goes to Y for contactors in outdoor
Brown goes to C or common
Blue goes to O/B for reversing valve
There I usually a white to Aux/E, but if you had orange to W2 that is probably your white.
Ok lets check your setup menu. Tell me what you have function 1 and 2 set to.
Do you have a voltmeter to check between the Red and brown to see if we have 24 volts?
If brown was C on old, this should be correct.
Themostat still dead?
Did you let that brown ire touch anything else? Look in air handler for a little 3 amp purple auto type fuse on board to be blown.
You will have to remove 4 screws holding panel in place (Not where coil is, but top panel)
4 screws (2 if older air handler)
What do you have function 1 and 2 set on?
Leaving office tonight.If you want to continue tomorrow,I will be around
