The following details refer to the water flow rate. If glycol mixtures are used, the different viscosities will result in deviations.
Nominal flow rate
Peak flow rate
Cut point ±3 %
Lowest flow rate (horizontal installation)
Lowest flow rate (vertical installation)
Pressure drop at approx. ⅔ of the nominal flow

The solar cell captures the intensity of the sun and communicates
this to the solar control unit. The bypass pump will be switched ON if
the insolation exceeds the set switching threshold.
With connecting cable, 2.3 m long.
On-site extension of the connecting lead:
2-core lead, length max. 35 m with a cross-section of 1.5 mm
per).
With power supply unit plug.

■ With setting scale and reset button in the casing
■ Required if less than 40 l cylinder capacity is available per m
absorber area. This reliably prevents temperatures above 95 °C in
the DHW cylinder.
