10.4 Pressure differential for heating medium side
The diagram below shows the total pressure differential for CTC EcoZenith i350 and the heat pump
specified by the curve to the right of the diagram. Curves from the pump diagram on the previous
page are added for reference.
Example for calculating speed of pump with required flow of 0.25 l/s
approx. 15 kPa pressure differential for CTC EcoZenith i350 + CTC EcoAir 510M at 0.25 l/s
approx. 50 kPa pressure differential for piping system in the house at 0.25 l/s
The total pressure differential through the heating circuit is approx. 65 kPa at 0.25 l/s
Compare to reference curves from pump curve included in the diagram.
Approx. 70% for PWM signal to charge pump may be a suitable setting.
