When using an external switch for changeover, the operating action is configured
via P150, P153 or P155 = 2.
P151 (X1), P154 (X2) or P156 (U1) = 0
(default, normally open)
P151 (X1), P154 (X2) or P156 (U1) = 1
(Normally close)

● Manual heating/cooling changeover means selection via changeover button on
the thermostat by repeatedly pushing the button until the required mode is
displayed.
● If manual heating/cooling changeover is commissioned (P001 = 3),
heating/cooling mode cannot be changed via bus/changeover sensor/switch; it
remains in the last mode selected locally via button.
The thermostat acquires the room temperature via built-in sensor, external room
temperature sensor (QAA32), or external return air temperature sensor (NTC 3k or
LG-Ni1000) connected to multifunctional input X1, X2 or U1.
Inputs X1, X2 or U1 must be commissioned accordingly. See Multifunctional input,
digital input [➙ 92].
