● The control action can be changed from normally open (NO) and normally
closed (NC) via parameter P39, P41.
● Each input X1 or X2 must be configured with a different function (i.e. 1…5 &
9…11). Exception: X1 or X2 input can be configured with same function (i.e. 6,
7, 8).
● X1 is factory-set to "Window contact" (3), X2 to "Room temperature external
sensor/return air temperature" (1).
If a multifunctional input is configured as analog: "Er3" is displayed when the output
is out of range (0...49 °C), open or shorted.
For detailed information, see Application overview [➙ 21].
● For inputs X1 and X2, one physical switch can be used for up to 20 thermostats
(parallel connection).
Caution! Do not mix X1 and X2.
● For sensors on inputs X1 or X2, the maximum cable length is 80 m.
