Hello, here is a script, you can make it resident.

Code:

summer = grp.getvalue('6/1/1') -- boolean if '0' is winter, if '1' is summer
winter = not summer
 
current = grp.getvalue('5/1/14')
setpoint = grp.getvalue('5/2/14')
running = grp.getvalue('6/1/0') ~= 0

hysteresis = 0.5

value = nil

if (running and summer) then
  if current < (setpoint - hysteresis) then
    value = 0 -- off
  end
elseif (summer and current > (setpoint + hysteresis) ) then
  value = 9 -- cooling
end

if(running and winter) then
  if current > (setpoint + hysteresis) then
    value = 0 -- off
  end
elseif (winter and current < (setpoint - hysteresis) ) then
  value = 3 -- heating
end

if value then
  grp.write('6/1/0', value)
end
