Similarly, the sub menu for valve control.
The „Inverted“ function inverts the switching
function of valves, e.g. if valve installation
does not comply with the standard.
The controller will then exchange energized
and de-energized conditions.
Continue to menu item ›Tube collector‹.
To receive correct measured values from
the tube collector system, the pump
must be switched ON briey.
By activation of the function, the
solar circuit pump can be started
time- and/or temperature-controlled.

...to dene the required control
algorithm as ›dT‹ or ›Fixed T‹.
In case of plants with long piping or slow
response, overtravel times for the solar
circuit, pump and valve can be determined.
Specify minimum and maximum output n-min
/ n-max of the pump.
