Code:
;================================================
heat:
if tempr <= wa then heater = 1
if tempr >= wa then heater = 0
pause 30
;return
;================================================
fa1:
if tempr <= fan11 then fana1 = 0
if tempr >= fan11 then fana1 = 1
pause 30
;return
;================================================
fa2:
if tempr <= fan22 then fana2 = 0
if tempr >= fan22 then fana2 = 1
pause 30
;return
;================================================
fa3:
if tempr <= fan33 then fana3 = 0
if tempr >= fan33 then fana3 = 1
pause 30
return
;================================================
end
If all is working like you want with the exception of the fans and the heater is working...
wa is word size and fan11/22/33 are byte size.

Could be some thing else but off the top that is what jumps out.
