Are you the proud owner of a Clearwater spa, but need to replace the original CL2000 control system? It may be a little more complicated than it appears, but it can be done. Fear not, we have it all explained here!

The CL2000 (part number 54305-0x) is a Balboa system designed specifically for Clearwater Spas. Often paired with the long, thin ML550 keyboard and using a specific software, it can manage one circulation pump and 4 massage pumps, most often in configurations of two two-speed pumps and two single-speed pumps, or two two-speed pumps, one single-speed pump, and one blower.

It is possible to replace the CL2000 with another Balboa system that is compatible with the original keypad, but it requires some compromises. First, you have to avoid the GL2000 trap: it seems as though the CL2000 should be compatible with the similarly-named GL2000, but it is not. The GL2000 can only handle one circulation pump and two massage pumps.

Balboa recommends the GL2001 control system as an alternative, and it is compatible with the ML550 keypad. It can manage, in addition to a circulation pump, up to 4 pumps but only in the following configuration:

  • Pump 1 two-speed,
  • Pump 2 single-speed,
  • Pump 3 single-speed
  • Pump 4 single-speed or blower.

Since the GL2001 cannot handle two two-speed pumps, you will lose the low speed on pump 2.

The GL84P is also a good replacement option, but it is expensive and often hard to find. You won't have to replace the ML550 keypad, although you may find that you want to change the functions of the keys, and activate the hidden button under the overlay ( contact us if necessary).

The BP2100 can replace the CL2000 in an installation with one circulation pump, two two-speed pumps, one single-speed pump and one blower. But replacing a CL2000 with an BP2100 also means replacing the ML550 keypad, as it is not compatible with the BP2100. You will need a TP series keyboard (TP400W, TP400T, TP600, TP800, TP900, spaTouch, etc).

The NEO 2100 from Waterway, paired with an expansion card (DB1 or DB2 depending on your configuration), allows you to manage up to 4 pumps in addition to a circulation pump. You will of course need to swap your ML550 keyboard for a NEO 2100.

To summarise, there are numerous possibilities, and your choice depends mainly on the configuration of the CL2000. Do not hesitate to contact us for more information, we will be happy to answer your questions!
