Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and did not receive that money. You have to supply a rating in order for us techs to receive credit for our time as we have nothing to do with any payment made to the site.

Can you list the wires you have and what terminals they are on the old control all of them?

1- pv
6- 24v
2- THS
4- Sense
5- Ground.
Expert:  HVAC Guru replied 9 months ago.

OK just put it as follows, first disconnect the black wire from the remote sense discard it

Then Connect as follows to the new unit from your list

1-PV

2- THW

4-FLAME SENSOR

5-24V Ground

Do not connect the 24 volt line #6 to the unit and also make sure the unit is grounded and that should be it.

I would like you to know that I am a tech that works for the site, the payment you made to the site is not automatically credited to me nor do I receive all of the payment you made. The only way I receive any credit at all for my time is by you selecting a STAR using the 5 STAR RATING SYSTEM on your page before you leave. If you are not happy with the service please let me know before leaving a negative rating. This will also allow you to get directly back to me for FREE follow up questions and tips are greatly appreciated! Thanks

Expert:  HVAC Guru replied 9 months ago.

Yes then it all should work, but your GROUND one on the old one needs to go to 24 VOLT GROUND on the new one and the others are equipment grounds to the frame.
