Code:
if  (pump=0) and ( thermistor1 or thermiko1 or ( onboard_an2>(pres_limit + 10))) then 
	module_rel_out.0=0
endif


if (level>stop_level) then
	if pump=0 then
		module_rel_out.0=0
	endif
endif
Compile fine

BUUUUUUT ... I do think you should make your Karnaugh Table ( Table of states ) "a bit" clearer ... might help a lot ( lol )
