TESTI NEI LAYOUT

Based on your description do it like that.
Tag objects v1,v2,v4  as you want  but not v4.  In my example it is setpiont, temp and delta but not switch.
Create event based script which will be triggered by your tag.

Code:

temp = grp.getvalue('Thermostat Temperature')
setpoint = grp.getvalue('Thermostat setpoint')
delta = grp.getvalue('Thermostat delta')



if temp >= (setpoint + delta) then

grp.write('Thermostat Switch', true)

else
  grp.write('Thermostat Switch', false)
end

Change group addresses as needed.
