Commissioning
Filling and commissioning may only be carried out by an authorised contrac-
tor. When doing so, the operation and water-tightness of the entire system,
including the factory-fitted parts, must be checked. Opening the ball valves
slowly at the module inlets and outlets will help prevent water hammer when
flushing the system. Continue filling and flushing until you are sure the system
has been entirely purged of air. Audible flow noises during operation indicate
that there is still air in the system, which must be bled out through the pump.
Exceeding the permissible operating pressure may result in leaks and
could destroy the cylinder.
The DHW temperature is controlled using the thermal fixed setpoint controller,
which is delivered preset to 50 °C. The setting range is factory-limited to 3.25.
You can delimit and set this range using the red and blue temperature memory
clips. Turning it clockwise reduces the DHW temperature.
It is recommended that you have the system serviced annually by a qualified
contractor.
Recommended cylinder temperature:
The cylinder temperature should be at least 12 K above the required DHW
temperature.
