Dear Trnsys users, I have a simple model of a SDHW-system, with a Type 2 controller. When I run the simulation, I get the message that at several times 'There is no stationary state ...'. I have noticed that this occurs always when (for the controller) deltaT > deltaTH or deltaT < deltaTL and when gamma-i is different from gamma-o, so this is when de pump switches on or off. I am probably doing something simple wrong, but I have no idea what. Thanks very much, Maarten Sourbron ------------------------------------------------------------ Projectingenieur Onderzoeksgroep Milieu & Energie De Nayer Instituut Jan De Nayerlaan 5 B-2860 Sint-Katelijne-Waver Belgie Tel: +32 (015) 31.69.44 Fax: +32 (015) 31.74.53 E-mail: mso@denayer.wenk.be
