M2 151
PID Slew
Rate Dn
Defines the speed (in °C/100 ms) with which the set-
point of individual modules is decreased in the event
the primary circuit's set-point is exceeded (if the value is
set to zero, the change is controlled by the PI of Par. 86
and 87 without restrictions).

Power
Defines the power value (in percentage terms) against
which the average power of all on modules in cascade
operation mode must be compared (Par. 148 = 2).

Defines the extra power value (in percentage terms)
compared to the average power of all on modules in
cascade operation mode (Par. 148 = 2).

Defines overrun time in seconds at the end of the cas-
cade heat demand.

M2 155
Frost
Protec-
tion
Defines the temperature (detected by the primary sen-
sor) below which the thermal module circulator and the
system circulator (with cascade configuration) activate.
If the temperature of the primary sensor falls another 5
degrees below the value set by Par. 155, then a request
to activate the cascade is generated. When the temper-
ature of the primary sensor reaches the value defined
by Par. 155 increased by 5 degrees, then the request
ceases and the cascade returns to stand-by mode.

increases or decreases provided for by Par.169 e 170.

M3 176 PID P
Defines the proportional term to change the set-point
of the cascade module based on the secondary circuit's
temperature.

Defines the integral term to change the set-point of
the cascade module based on the secondary circuit's
temperature.

M3 178
PID Slew
Rate Up
Defines the speed (in °C/100 ms) with which the set-
point of individual modules is increased in the event the
secondary circuit's set-point not reached (if the value is
set to zero, the change is controlled by the PI of Par. 176
and 177 without restrictions).

set to zero, the change is controlled by the PI of Par. 176
