The Hunter ICC-FPUP2 kit replaces the control electronics in an original ICC controller, upgrading it to ICC2 control. It can be used when repairing a failed ICC facepack, power module or ribbon cable, while retaining the existing cabinet, transformer, compatible station modules and field wiring. It includes the ICC2 facepack, power module, cabinet and pedestal ribbon cables, and quick-start programming guide.
The new facepack provides a large backlit display and local dial-and-button programming. The current retrofit instructions show flow-enabled ICC2 controls with dedicated flow and weather-sensor connections. A compatible HC Flow Meter is required separately to measure flow and use the flow alarms.
ICC2 programming provides 4 independent programs with 8 start times per program and station run times from 1 minute to 12 hours. Scheduling includes days of the week, odd/even dates and intervals up to 31 days. Up to two programs can run at once, plus the P/MV output, where the installation supports the combined load.
The kit does not add station outputs. Capacity depends on the station modules retained or added to the existing installation. With compatible ICM modules, conventional capacity can reach 38 stations in a plastic cabinet or 54 in a metal cabinet. Check the original controller, cabinet and installed module layout before selecting expansion parts.
For two-wire operation after the retrofit, add a compatible EZ-DM (ICC2 / HCC) output module and EZ-1 or EZ-LR field decoders. Both plastic and metal versions can support up to 54 total station numbers. Conventional and decoder outputs share that range in a hybrid layout. Follow the EZ-DM guide for module positions and station assignments.
A separate weather input accepts suitable Clik sensors or an optional Solar Sync for weather-based run-time adjustment. Centralus online management requires an additional compatible communication module. ROAM or ROAM LR remotes can be used through a suitable SmartPort connection.
Installation replaces the facepack, power module and connecting ribbon cable. The cabinet, transformer and suitable station-output modules remain in place. Follow the retrofit instructions and disconnect AC power at its source before changing the control components.
For an original ICC with a failed facepack, power module or ribbon cable, the kit provides replacement control electronics and upgrades the controller to ICC2. The existing cabinet, transformer and station modules must still be serviceable.
5 Year Hunter Warranty.

How two-wire decoder wiring works
The explanation below applies after the compatible controller has been fitted with this retrofit kit and the separate EZ-DM decoder output module. The retrofit kit alone does not provide a two-wire decoder output.
Conventional valve wiring uses a separate station wire from the controller to each watering station, together with a shared common wire. A two-wire decoder system uses a shared pair of field wires to carry power and control signals to decoders near the valves.
The EZ-DM output module fits inside the compatible controller. Each EZ-1 or EZ-LR field decoder connects to the shared cable and a local valve solenoid. It is programmed with a station number. Starting that station operates the valve connected to its decoder.
The cable can branch in different directions to reach separate valve locations. At each split, join each conductor separately using suitable waterproof irrigation connectors inside a valve box. Both branches remain part of the shared two-wire path.
EZ-DM supports up to 54 total stations in both plastic and metal cabinet models. In a hybrid installation, conventional outputs and decoder stations share those 54 station numbers. Assign decoders to numbers not already used by conventional outputs. Follow the EZ-DM guide for the module layout.
Choose cable size for the distance to the furthest decoder and the number of solenoids running at the same time on the shared path. More simultaneous solenoids reduce the permitted distance. Include a master valve if it is operated through a decoder. Use the EZ-1 or EZ-LR wiring tables in the guides above.
