CT3200 and T87F Wiring issue

[atech535]

The CT3200 manual makes a no sense at all......

Old T87F has terminals -
B, R, Y, W, G

5 wires from the wall, all of coresponding colors.

New CT3200 has terminals -

W, Y, G, R, Rc - jumper between R and Rc.

House system is gas heat/central air

Help!!

The 3200 is a very good replacement for a heat/cool unit.First, try the 4 wire set-up with the jumper intact; R = (power).. G= fan relay.. Y= cooling contactor...W= heat relay. IF the unit will not kick in, put "B" on RC (remove jumper).. let us know how you make out. Hube
