I bought a honeywell rth6300b programmable thermostat and it has connections g,w,y,r,rc with a jumper between the r and rc. My old thermostat had a c,r,w2,g,e,o,y wires can I even hook this up or do I need to get a different thermostat. Thanks in advance for any help I read several entry's prior to getting it and it seemed simple I guess I should have looked at the old one first??

You need to get a heatpump thermostat, one stage cooling two stage heating. You have a heat/cool only thermostat it can't be used with a heatpump.

Thanks I'll return it and get what I need. Will all these wies be represented on the heat pump thermostat? And thanks for the help.

I am not suggesting you buy a thermostat from this site

But just look at models available for reference

Heat Pump & Multi-Stage Thermostats

Honeywell Thermostat: Full Programmable honeywell thermostat line

Yes they will just follow the instruction with your new t-stat.

Thanks for all the help Great site probably hear more from me I am always trying to do something I shold pay someone to do but learning as I go.

We all learn from trying. Good luck.

I got a rth7000 honeywell and all wires matched up except I have a w2 and it does not show on the heat pump side but does on the conventional side so I hooked it there. Cooling is working fan is working heat and auto fan are not??

Do you have a jumper from rh to rc? How do you have it wired?
