The factory settings are underlined and in bold print in the table above (ON
)
(1) The operating mode can be changed with the
button on the controller,
by means of a window contact, occupancy detector or otherwise (terminals
DU1-GND). Input DU1-GND has a higher priority than the
button.
(2) In case the controller is in the reduced operating mode, any operation carried out
on the front of the controller changes the mode immediately to the normal operat-
ing mode. Note that the set-point offset is not active in the reduced operating
mode.
