1. Introduction

A thermal solar installation is thereby more susceptible to errors than conventional heating systems, because

• the system becomes actually more complicated

• new techniques and components often become "tried out" and

• a control by the user is difficult

It is therefore necessary to develop suitable assistance programs which help the user to analyse the disposition of the installation, to identify errors and to eliminate them.
