[TRNSYS-users] Heating limit temperature

[Jeff Thornton]

<No! I would like to turn off my heating in case the average daily
temperature is HIGHER than 12°C !! The main idea behind this is to
represent the amount of heating days (depending on the climate zone,
mostly 222days)> 

Do you want to look at the last 24 hours when making
your decision or the current day? If you want to look at the last 24
hours then use the moving average calculator. If you want to look at the
current day (which would in reality require a forecast) then you should
pre-process the weather file and create another data file which contains
the "on" or "off" signal for the day. But to be honest, if you've got
the model correct, a standard thermostat will turn on and off the
heating equipment when it's needed and you can adjust the building
parameters and occupant behavior to tune the model to get to your
magical 222 days (not sure how you got that number).

use the moving average or the integrator??

because my first ambition was just to calculate Qheat. But if my
simulation won´t end at calculating, but using the net Qheat it´s a very
uncomfortable solution.
