Call the company

Wiener dog, that sure wasn't a DIY answer now was it. If you can't answer the question just let it go, someone else can actually help. Here is an old thread from Northernheat that explains the wiring https://www.askmehelpdesk.com/heatin...tml#post268211 Remember to jumper the two reds to each other Rh and Rc, this is done if you have but one 24 volt transformer.
