BOOSTER CONDIZIONATO

Like this:

Code:

event_value = event.getvalue()
summer = grp.getvalue('7/0/0') -- summer / winter

if event_value then
  out_value = grp.getvalue('3/3/1')
else
  out_value = 0
end

if summer then
  out_addr = '6/0/91'
else
  out_addr = '6/0/101'
end

grp.write('2/0/91', event_value)
grp.write(out_addr, out_value)

Your current script will fail with an error because you have single "-" instead of double dash for a comment.
This line will be evaluated an arithmetic expression "X = A - B / C"

Code:

value_3 = grp.getvalue ('7/0/0') - summer / winter
