this is my variant of a script that will set the flow temperature depending on the exterior temperature and the inside desired temperature:
Code: Select all
-- This script will set the flow temperature of a heating system based on the external temperature and the
-- internal temperature of the room.This is done with the help of the heating curves that are defined based
-- on the desire and the needs of the room u wish.
-- Also the script will set the desire flow temperature based on the type of the heating system u have: underfloor or
-- radiators. In one of this states, the script will automatically keep a minimum and maximum flow temperature depending
-- on the state of your settings (underfloor or radiators). Also a manual state can be set where u set the temperature
-- at any value u want.
-- Define a threshold for exterior temperature change to trigger the script
-- U can set here how many degrees the outside temperature need to change before the flow temperature will be changed to the next value from the coresponding heating curve
local tempChangeThreshold = 2 -- Adjust this value as needed
local decimalNumber = 1 -- this is the noumber of decimal for the temperature sensors
-- Define heating curves based on your requirements
-- The heating curves will be set as follow: temp - is the outside temperature; pardosealaFlow - is the underfloor temperature
-- u want for the coresponding outside temperature; calorifereFlow - is the radiator temperature.

the 'global_data' script contain some global persistent variable that i use in the scripts i made including this one (useful for the future modification of my setup) and also a rounding function that round a number depending on the amount of decimals someone desire (i made this because i didn't know what the correct function is (if exist) in dzvents. the way the rounding is done is like this: if u want to round at 1 decimal, we look at the 2 decimal and if that is under 5, the 1-st decimal will remain unchanged. if the second decimal is >5 then the 1-st decimal is increased by 1. if the second decimal ==5 we look at the 3-rd decimal and if is <5, first decimal remain the same if 3-rd decimal>5 then 1-st decimal is increased by 1 and so on. we can do that for 0, 1, 2, 3, ... n decimals.
if someone know the correct function in dzvents that does this kind of rounding please poste it here !!
