10.4.7 Sensors
Cut-off time constant These constants are used for calculating the filtered temperature (see page 42). The
controller calculates filtered values of outdoor and/or room temperatures, depending
on what sensors are connected to the system.

Sensor time constants concern Pt 1000, ESMF and 0–10 V sensors. Pulse and digital
sensors are not affected by the time constants. See page 30 for information on sensor
setup.
