Temp.
Limit
Sets the activation temperature when the maximum
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.

Mini-
mum
Sets the value of the temperature difference (Delta T)
between the module's delivery and return temperature.
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.
