20.7 H&L LOCAL TEMPERATURE PROTECTION
This function, available for all units connected to the LAN network (P26.01>0) and that adjust according to the average temperature (P26.02=Y), permits monitoring the
formation of Hot and Cold Spots in a room controlled by various units on the LAN network.
INFORMATION
The function can be viewed only after enabling the LAN network and adjustment according to the average temperature.
The protection is enabled so that the air temperature in the room is not too high or too low, according to the following criteria:
•
Hot Spot protection:
•
Cold Spot protection:
When the function is activated as a result of one of the above limits being reached, it "frees" the protected unit from having to adjust according to the average temperature, so
that it can adjust according to its own local air temperature, and the temperature fault detected in that individual unit can be managed independently.
After the local air temperature has been brought by the independent unit back within the Hot Spot and Cold Spot limit for the time in parameter P26.14, the unit is
reconnected to the LAN and made to adjust according to the average temperature.
INFORMATION
This function is available for units in standby and in ADL mode, which must be configured for adjustment according to average temperature and
humidity.
INFORMATION
The parameters for setting and enabling this function can be viewed only at the Master unit.
