STARTF Start function: start help for solar thermal systems.
ART After-running time: can be set for the output.
PSC Pump speed control (only for speed version VD)
COP Control output (0-10V / PWM)
As analogue function (0-10 V): output of a voltage between 0 and 10 V.
As fixed value of 5V to supply vortex sensors without data link connection.
As PWM (pulse width modulation): output of a frequency. The duty cycle (ON /
OFF) conforms to the control signal.
Error message (switchover from 0V to 10V or inversely from 10V to 0V)
F CHCK Function check: activates a monitoring function to detect various errors and critical
situations.
HQC Heat quantity counter - activate and make settings
EXT DL External sensor values from the DL bus.
Language DEUT, ENG
Language selection: The entire menu can be switched to the desired user
