10.4.7 Sensors

Cut-off time constant
Time constants
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.

Tout circ. 1 Outdoor tem-
Tout circ. 2 perature, cir-
cuit 1 or 2
Troom circ. 1 Room tem-
Troom circ. 2 perature, cir-
cuit 1 or 2
These time constants are used to convert the input signals received from sensors con-
nected to the system.
Note:
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.
