a) General Information
The operation of the "FS20 ZPS" circulating pump control is carried out with just three buttons
and the rotary encoder. The "FS20 ZPS" has a simple menu (see next page) with which all
relevant settings items and information can be quickly selected.
The three buttons have the following functions:
"OK/Menü" button
• One menu level down
• Selection of settings
• Confirmation of inputs
"Profil" button (= "profile")
• Direct selection of sub-menu "Select profile" (= "Profil auswählen")
"zurück" button (= "back")
• One menu level up
• Selection of previous input field
• Quitting a menu/function (hold down button)
After the "FS20 ZPS" is switched on, the current temperature at the outflow and return sensors,
the current weekday and the current time are shown on the display, this is known as the basic
display. In addition the name of the currently used profile is shown every 5 seconds.
You can reach the main menu using the "OK/Menü" button.
You use the rotary encoder to select the next sub-menu and press the "OK/Menü" button to
move to the next menu level.
