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.
To enable this function, the multifunctional input, to which the supply air sensor is
connected, needs to be set to "Supply air sensor" (e.g. P38=9). Then the
parameters for the limits are visible (P63: minimum supply air temperature,
P64: maximum supply air temperature).
This function is only active in Comfort mode and can only be used with DC 0...10 V
actuators.
For applications with electric heater, this function is not available.
