Defines the temperature (detected by the primary sen-

system circulator (with cascade configuration) activate.
Frost If the temperature of the primary sensor falls another 5
M2 155 Protec- degrees below the value set by Par. 155, then a request
tion 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.
