Mains switch
Switching the ROTEX GSU on and off When the heating system is on, the mains switch is illuminated in green.
Collective fault signal
During normal operation, the collective fault signal is off. If it lights up, this indicates a malfunction.
Pressure gauge
– Black pointer: Indication of the current water pressure in the heating system.
– Green range: Permitted water pressure range.
– Red pointer: Indication of the permitted minimum pressure.
The black pointer must be in the green range. If it is to the left of the red pointer, the water pressure must be raised by topping
up the system.
The ROTEX GasSolarUnit can be operated with the THETA 23R control or only with the ALPHA 23R control.
The electronic digital controls are to be used for controlling 2 heating circuits (direct heating circuit, mixer
circuit) and a storage tank charging circuit.
A more detailed description is given in the documentation of the "ROTEX Control". It is part of the scope of
