Which pumps each one drives
The two controllers are nearly identical. They differ in which pumps they drive: the TV-401/301 Navigator drives both the Turbo-V 401 and the Turbo-V 301, and the TV-301 drives the Turbo-V 301 only.
What usually goes wrong
Behind most faults on both sits one of these circuits:
- The power supply
- The motor driving circuit
- The control and communication circuits
