The base model of the Hunter HCC or Hunter ICC2 are supplied with 8 stations. The capacity of the controller is increased when new station modules are installed and recognised.
Standard ICM modules are available in 4, 8 and 22 stations sizes.These maybe added at anytime after initial installation.
N.B. The ICM-2200, 22 station module should always be installed in the last two module slots to make it compatible.
