Each project with differential controller needs to base exclusively on customer design
and calculations and needs to be in compliance with valid rules and regulations.
Pictures, diagrams and text in this manual are intended solely as an example and
the manufacturer does not accept any responsibility for them. If you use content
of this manual as a base for your project, then you carry also full responsibility for
it. Responsibility of publisher for unprofessional, wrong and false information and
consecutive damage are explicitly excluded. We retain the right for technical errors,
mistakes, changes and corrections without prior notice.
Installation of controlling devices should be done by an expert with suitable
qualifications or by an authorised organisation. Before you deal with the main wiring,
make sure that the main switch is switched off. You have to follow the rules for
low-voltage installations IEC 60364 and VDE 0100, law prescriptions for prevention
of accidents, law prescriptions for environmental protection and other national
regulations. Before you open the housing make sure all poles of electric supply are
disconnected. Not following the rules this may lead to serious injuries such as burns or
even risk of death.
The controller must be connected to the power supply via a separating switch for all poles. The
distance between poles by open contact must be at least 3 mm.
The relay R2 is designed as semi conductor relays for pump speed control.
All low-voltage cables, such as temperature sensor cables, have to be routed
separately from mains voltage cables. All connections of temperature sensors are
carried out to the left, and main voltage connections to the right side of the controller.
