3 state heating systems

[electrokinisi]

Hello guys, 
I need some help to prepare the code for the following function.
I have 3 heat pumps and 13 thermostats.
I want the first heat pump to start when 1 to 4 thermostats are requested,
 the second pump to start after 5 to 8 thermostats, 
and then the third pump to start when 9 to 13 thermostats are requested.

Thanks in advance .

You can use OR gate from this script: https://forum.logicmachine.net/showthrea...7#pid28367

Thank you for the answer,
but I didn't explain it exactly.
I want to randomly add the commands of the thermostats and depending on the demand to start the pumps in stages.

Attach a common tag to all thermostat on/off objects then attach an event script to this tag. 1/1/1..3 are your heat pump control objects, modify as needed.

Code:

objs = grp.tag('thermostat')
count = 0

for _, obj in ipairs(objs) do
  if obj.value then
    count = count + 1
  end
end

grp.write('1/1/1', count >= 1)
grp.write('1/1/2', count >= 5)
grp.write('1/1/3', count >= 9)
