Need to find a way to have 1rst stage heat energize existing boiler feeding basebord - so when t-stat calls heat in first stage - it does NOT energize reversing valve, fan, and compressor; but in 2nd stage (aux) it DOES energize RV, fan, and compressor - have it working the opposite now - but would rather have baseboard as 1rst stage - best I can figure is to use 4 seperate switching relays - but with 5 seperate pumps this is somewhat costly and its hard to make the wiring for four relays not look unsightly -
I Didn't Do It!!!

maybe a zone board would work,then just switch wires from board to t-stat..but arent you afraid of frozen pipes when you switch to second stage??
