CAUTION!:
With low flow rates, a very hot buffer tank and a high setpoint temperature at
the thermostatic valve, hot water temperatures of > 60°C can occur depending
on the control unit. In objects where scalding protection must be provided, a
thermostatic outlet fitting must be provided at the tapping points.
A non-return valve [4] is installed in the connecting valve of the control valve to prevent
miscirculation in the primary circuit.
It is not possible to manually open the return valve.
The STS02AC flow sensor is installed vertically and clipped
onto the measuring section.
Attention! Before disconnecting, it is essential to
disconnect the system from the power supply.
When replacing the flow sensor, observe the direction of
flow, which runs from top to bottom.

3 = approx. +40 °C WW temperature
4 = approx. +48 °C WW temperature
5 = approx. +56 °C WW temperature
6 = approx. +64 °C WW temperature
Preset and recommended setting is 3.5.
