First I want to thank you for taking the time out of your day for answering my question.
I have a Honeywell wifi thermostat product  number RTH6580WF1001 that I am trying to hook up to a 5 wire rooftop package unit electric heat pump. this thermostat requires a C wire or a common wire with 24 volts to power the unit. Out of the 5 wires only one of the wires has power to it. It is the red wire that is connected to RH on the old thermostat with a jumper wire to RC.  There is also a jumper wire from W to Y on the old thermostat.  Any information on how to hook this thermostat up would be greatly appreciated. I am going to send you the pictures that I have and a few diagrams that I drew up. I hope they help. Let me know if you have any questions. Thxs.  It will only allow me to upload 2 photos so if you email me back then I will reply with the other 5 or 6 photos.

Use my personal email at,    there is no cross reference on the stat end from the new stat?

using my personal email you can send anything you want,   but there is not a cross connection on the Honeywell?

a long link  but it has every Honeywell connection in the world I think   might be something there until I get the rest of your photos,

The above link should be a help
