Il parametro abilita la funzione di limitazione della temperatura superficiale di un
pavimento riscaldante. Per la funzione è indispensabile misurare la temperatura
superficiale del pavimento mediante l’abilitazione del sensore di temperatura
corrispondente nella scheda Sensori esterni (dal bus) o nella scheda Ingressi.
Important!
This function does not replace the overtemperature protection usually
installed in hydronic floor systems, realized with a dedicated safety thermostat.
Temperature limit [°C]
Floor temperature limitation = enabled
29
[range 20
… 40]
According to EN 1264 a maximum allowed temperature is prescribed for the surface of
a floor heating system:
•
T(sup)
max ≤ 29°C per le zone di normale occupazione;
•
T(sup)
max ≤ 35°C per le zone periferiche degli ambienti.
National standard may limit those temperatures to lower values. Per zone periferiche si
intendono
fasce situate generalmente lungo i muri dell’ambiente rivolti verso l’esterno
dell’edificio con larghezza massima di 1 m.
Hysteresis [K]
Floor temperature limitation = enabled
0,3 K
[other values in the range
0,2 K … 3 K]
Before quitting from the alarm status, the device waits until the surface temperature
decreases under the threshold set offset pari al valore di isteresi.

Disabled from bus
Auxiliary heating = enabled
no
/ yes
It enables the activation and deactivation of the function through a telegram sent on
the bus by a supervising device.
Offset from setpoint
Auxiliary heating = enabled
0,6 K
[other values in the range
0 …3 K]
Hysteresis
Auxiliary heating = enabled
0,3 K
[other values in the range
0,2 K … 3 K]
Cyclic sending interval
Auxiliary heating = enabled
no sending
[other values in the range 30 s
… 120

Ventilation for auxiliary heating
Heating type = floor radiant panels or
ceiling radiant panels
disabled
/ enabled
This option allows matching a system with high inertia as the floor radiant panels
(hydronic version) to a system with low inertia as the fan-coils.
