When the operating mode is changed from Comfort to Economy or Protection, the
relay contact remains energized until the end of the minimum on time set via P212.
4.6.4 Monitoring and limiting functions
The floor temperature should be limited for two reasons: Comfort and protection of
the floor.
The floor temperature sensor, connected to multifunctional input X1, X2 or U1,
acquires the floor temperature. If the temperature exceeds the parameterized limit
(P252), the heating valve is fully closed until the floor temperature drops to a level
2 K below the parameterized limit. The factory setting of P252 is 28 ℃.
Input X1, X2 or U1 must be commissioned accordingly (P150, P153, P155 = 11)
and the type of sensor need to be selected (P151, P154, P156 = 2 (NTC 3K) or 3
(LG-Ni1000)).
See Multifunctional input, digital input [➙ 112].
● Living rooms:
Up to 26 °C for extended presence, up to 28 °C for short presence.
● Bathrooms:
Up to 28 °C for extended presence, up to 30 °C for short presence.
The "Floor temperature limitation" function influences the outputs listed in the table
below:
*) If P027 = ON, electric heater in cooling mode.
Either floor temperature sensor or external room temperature sensor can be used.
This function increases the comfort in the room by keeping the supply air
temperature of the fan coil unit between the selected minimum and maximum
temperature limits.
If the supply air temperature exceeds a limit, the thermostat reduces the
corresponding valve position until the supply air temperature is back in the limits.
In case the air flow is too low (especially with DC 0...10 V fans), this prevents cold
air from dumping into the room/warm air from bubbling straight up instead of
circulating.
