switch-off due to temperature control.
Sets the activation temperature when the maximum
flue gas temperature is exceeded. When the flue gas
temperature is higher than a set value, the mod-
Flue
ule switches off and an error message is generated.
M1
6
Temp.
When the flue gas temperature is in the interval
Limit
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.
CH Hys-

which the burner switches off for thermoregulation.
CH Hys-
Sets the value in degrees below the set-point at

Sets the stand-by time before the appliance is
switched on again after it switches off due to ther-

switches on again notwithstanding from the time
Diff.
spent at Par. 9.
Sets the value of the temperature difference (Delta T)
between the module's delivery and return temper-
ature. For a Delta T value ranging between Par. 12
and (Par. 12) +8°C, the module reduces its power in a
Hx diff.
linear fashion until it reaches the minimum power.
M1
12
Minimum
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.
