Hello there! I'm Norman but you can call me Norm. Let's see what I can do to get you some answers today. I'm ready to get started whenever you are.
Hope you are doing well today.
Was your old thermostat a RTHL2510/RTHL2410 as well or a different model?
No but was a honeywell
Ok, what color wires went to what terminals on the old thermostat? Do you stil lhav ethat?
G green W white
And you didn't have a C wire before?
B blue I think that is it
I think that's what the problem. Pull the B loose and cap it. Then replace the fuse.
I don't think so
Ok I'll try it
Your old thermostat required a B (common). It's probably an older Trane unit. On this thermostat B is not for the common wire. It's for energizing a reversing valve in heating which you don't have. Therefore when your thermostat calls for heat it's directly shorting the common to the hot on the W terminal and blowing the fuse.
So far it didn't blow the fuse but it takes a few min. for the thurmstat to kick in
I'll be right here to help. Let me know how it's going.
It seems to work and I can smell the heat coils heating up
This is a common mistake when changing thermostats.
I guess that is it thanks
Can't blame you. You see B and think, okay needs to go to B on the new one.
I'll hold tight here for another minute if you'd like?
OK Color codes I think I'm old school on them BK black BRN brown B blue
LOL, it happens.
