My name is Billy.
What is the thermostat model number?
on the very far left dont you have a W 4th space from top?
or a w/o/b terminal
ok you have the heat pump version...and I assume you do not have a heat pump?
You want a RTH7500 (without d)
Your current thermostat with L E (electric back up) )/B(heat pump reverse valve)..is set up for a heat pump
There could be work around if you want me to check...but the codes will not match
That is why you didnt see a W....
my personal thought is to get a thermostat that matches your system and letters...
If you are all set just rate service and I will close.
I apologize but until service is rated the system forces a response from me...
Just rate and then I do not have to respond.
For some reason the system is still showing as open...help me close by rating the service at top of page...then I can move off active list.
were you able to get a different thermostat installed?
