Analog Inputs
The unit is equipped with two analog inputs (for connection to
a room sensor and to a wall module with temperature setpoint
adjustment, respectively).

°C, this is interpreted as a sensor break / short circuit.
Analog Output
The W7754R, W7754T, and W7754V feature an analog
output which can be used to control
a variable speed fan, or
a proportional valve (provided that, via the LNS plug-in,
OUT1 has been configured for “PWM” and the fan has not
been configured for “variable speed fan”), or
a 6-way valve (provided that, via the LNS plug-in, OUT1
has been configured for “Not USED,” OUT2 has been
configured for the “Changeover Mode” of type “Floating
Mid,” and the fan is not using the analog output (no fan or
1…3-speed fan)).
