11.23External changeover
Using the "External changeover" function, you can use an on-site switch
at
terminals WF123 (pink) to change the operating mode of a heating circuit.
This is where you configure this control unit input.
The menu item "External changeover" will only be displayed if "None"
was
selected under parameter "Remote control".
This parameter will also not be displayed if the "Room controller" heating system
has been selected, since this requires the installation of a remote control unit.
This function is turned off at the factory.
You may select from the following two changeover functions:
Changeover 1 Day/night via terminals WF1 and WF3
Changeover 2 Day/night/aut via terminals WF1, WF2 and WF3
This may only be enabled if terminals WF1 and WF2 are not assigned to
"External fault message pump".
Call up the service level. "Gen. parameters" is shown as the first main menu.
Turn the rotary selector until the main menu "Heating circ. + no." appears
(here:
"Heating circ. 2").
Press "Display" to call up a submenu (here: "Heating system").
The display shows the selected submenu.
Turn the rotary selector until submenu "External Day/night/aut" is displayed.
The display shows the selected submenu.
