Defines the maximum decrease in the primary
circuit's cascade set-point. Is based on the
secondary circuit's probe reading.

Defines the time in minutes from the moment
the request is triggered until the activation of the

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).

M3 179 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 ex-
ceeded (if the value is set to zero, the change is
controlled by the PI of Par. 176 and 177 without
restrictions).
