The CPP-2 has a cold-water solenoid to allow you to either cool the process down below room temperature, or to quickly lower the temperature of the water bath (i.e. changing from a C-41 process at 38 deg C to a RA-4 process at 35 deg C).
The CPP-2 uses an integrated digital thermometer which allows it to hold the temperature of the process to within +/- 0.1 deg C.
It's much easier to set the temperature on the CPP-2. You program the temperature using three knobs for the tens, ones, and tenths of degrees.
The CPP-2 displays the water bath temperature on a digital LED readout.
