Waveform
Two waveforms are available for motor control. (ex works = WAVEP)
WAVEP Wave packets - only for circulating pumps with standard motor dimensions. Here,
individual half cycles are bled in to the pump motor. The pump runs on pulses and
only produces a smooth flow of the heat transfer medium when the rotor’s
moment of inertia has been overcome.
Benefit: Great dynamics of 01:10, well suited for usual commercial pumps
without internal electronics and a motor length of around 8 cm.
Drawback: Linearity depends on the pressure loss; there is some noise, not
suitable for pumps with evidently deviating motor diameters and / or length from
8 cm.
Wave packet control is not suitable for electronic or high efficiency pumps.
PHASE Phase angle - for pumps and ventilation motors. The pump is switched to the grid
within each half cycle at a certain point (phase).
Benefit:
Suitable for almost all motor types
Drawback:
Low dynamics of 01:03 for pumps. The device has to have a filter
upstream to fulfill the CE standards for interference suppression
NOTICE
The menu allows a choice between wave packet and phase angle however in the
standard version the output of waveform "phase angle" is not possible.
Special versions on request.
