[TRNSYS-users] Record external temperature at each time step

Mon Dec 7 00:47:31 PST 2009

Hello!

You many use TYPE93 "Input Value Recall", save Your 8 values, direct every
of them into an equation and test it all of them are <15°C
(boiler=lt(Temp1,15)*lt(Temp2,15)*...)

With kind regards,
    Matthias Kersken

Betreff: [TRNSYS-users] Record external temperature at each time step

I’d like to know how to make this: if external temperature is under 15°C
during 8 hours, I start the boiler.

So is it possible to record external temperature at each time step and count
if I have 8 times the external temperature under 15°C ?

How can I make that ?

Thanks for help
