Flue
Temp.
Limit
Sets the activation temperature when the maxi-
mum flue gas temperature is exceeded. When the
flue gas temperature is higher than a set value,
the module switches off and an error message is
generated. When the flue gas temperature is in
the interval between (Par. 6) -5°C and Par. 6, the
module reduces its power in a linear way until it
reaches minimum power when the temperature
measured is equal to Par. 6.

Hx diff.
Mini-
mum
Sets the value of the temperature difference (Delta
T) between the module's delivery and return tem-
perature. For a Delta T value ranging between Par.
12 and (Par. 12) +8°C, the module reduces its power
in a linear fashion until it reaches the minimum
power. The minimum power is maintained until
reaching (Par. 12) +8°C+5°C, after which the module
switches off for a period of time equal to the value
attributed to Par. 13; at the end of this time interval,
the module switches on again.
