installing honeywell rth7000 to rheem system
On my old mercury manual rheem thermostat, wires were connected as such:
white to w2 and e
yellow to y
brown to x
green to g
red to r
blue to b
there is also an orange wire that is not used.
I wanted to upgrade to a digital, programmable thermostat, so I got this honeywell rth7000. The way the old one was connected does not match anything in the installation, and it tells me to call a contractor.
I have a unit outside and one in the attic. My assumtion is that this is very typical.
My options on this new thermostat are:c
g
y
o/b
rc
r
and on the other side
aux
e
l
Any help would be appreciated. I getting very flustered.
