SECTION 1 - INTRODUCTION
BACKGROUND
The SMT 400 is a high specification integrated solar heating controller, compact,
robust and easy to use. This controller has evolved as a result of research and
development and years of experience in the solar industry. It forms a valuable
information system for the modern-day user and provides the necessary details,
revealing the performance of the solar system. The large graphics display ensures
that the unit communicates with the user with the greatest of ease and friendliness.
