PID-thermostat: help

[Amelie]

You need to restart the script when heating/cooling mode changes because PID instance (p variable) is only created once the script starts.

Attach an event script to 1/6/4:

Code:

name = 'pid' -- resident script name script.disable(name) script.enable(name)

Resident script can be simplified:

Code:

-- init pid algorithm if not p then   inverted = not grp.getvalue('1/6/4')   p = PID:init({     current = '5/2/8', -- actual temperature     setpoint = '1/4/11', -- desired temperature     output = '1/4/4',  -- valve     inverted = inverted,   }) end -- run algorithm p:run()

Thank you very  much! I was looking for a solution in that direction, but your proposal is much nicer than mine (and compacter).

Another question: the programmer/installer has made a resident script for each badroom. So, I have 4 scripts like that. Can I combine them into 1 resident script and working with a p1 for room 1, p2 for room2, p3 for room 3 and p4 for room4. Would it be less taxing for the LM?
