Hello I have a york furnace 1996 model. control board blew about 2006, replaced with newer version. Old board had heat park and park terminals I dont think it even had cool terminals. This is a heat only furnace as in no cooling so blower motor black wire is connected to heat terminal. This new board has heat/hicool/locool terminals. I have window a/c units so I thought I would use the fan only option on my honeywell programmable thermostat to circulate air. No go. Ended up being since the blower is only hooked up to heat, the blower didnt come on. Switch the black blower motor wire to hi cool and it comes on. question is, can I just tie hi cool and heat terminals together so I will have blower action when I need heat this winter and be able to just have fan only? Ok I just hooked black to hi cool and blue to heat. Hoping thats correct. What is the proper wiring method. numbers on control board are 879598 1162-202 1538 model of furnace pbkm-ld14n100c.
